farmers cultivate weed in mountainous regions for a reason. different height levels from sea level produces different qualities of plant like high medium and low grade. the best stuff always comes nearest the top fields where uv levels are higher. the grade of soil plays a factor in this also. in short yes uv light will induce a sexually frustrated female plant into producing more resin for two reasons 1 in the hope of capturing a little bit of pollen so she can reproduce and 2 the extra resin acts as a sun screen to protect the plant from higher radiation levels in turn raising the thc levels even more. honestly uv light works
Yeah i got the mars hydro ts3000 quantum board with 1000 leds and two meanwell drivers of which both drivers have adjustable screws to control the uv and white leds independently ( you could crank the leds down and the uv up).....I'm thinking maybe for THIS very reason.....
Yeah yeah IR is what i meant.....SAME thing as uv in late bloom......at least that's what I've read.....I'm brand new to the indoor gardening game so having one of the BEST quantum boards on the market was probably overkill.....but i ALSO have the healthiest looking starters after just 29 days....so thick you can't even see the dirt in the buckets anymore.....barely ANY stretch and I'll have to trim them just to water em........BUT I'll guarantee you it works very WELL for the 450$ it cost
The reason why adding UV light increases the thc percentage is very simple. UV is actually a harmfull wavelength for plants, plants feels it's presence and as a response the start making more resin for protection. The resin protects the plant structure.
You nailed it.. Cannabis developed their unique trichome structure and chemical compounds to help filter out UV light from hitting the seed pods which could potentially damage the seed and it would seem THC plays a big part in that protection. Not to mention the oftentimes bitter taste, extreme stickiness and disorienting effects of that chemical concoction in which is unpalatable and undesirable to most animals (aside from us of course). It makes you wonder if enacting other common threats that they would naturally encounter might increase other compounds as well.
My understanding is CBD binds with receptors in the body more easily than THC therefore consuming buds with high THC & CBD is counter intuitive. Higher CBD reduces THC uptake in the body. My medicinal preference is for high THC (up to 20%) low CBD flowers. Lower CBD to THC ratio means I need to consume less for the desired medicinal effect. The less I consume the healthier (and cheaper) it is for me. That's my opinion based on my own knowledge and consumption.
I hear what you're saying. But the entourage effect and a lot of research would say that CBD actually increases the effects of THC at the right ratios. My personal experience mixing and vaping thc and cbd flower together has made me think that it's probably right. It really does work that way to an extent, give it a shot though, ymmv. We all experience cannabinoids differently
If marijuana could cure schizophrenia the amount of money spent would never go in to r&d to devolve such strong weed to save us money and make it better for us. If you think about it thc is literally the psychoactive part so by eliminating the cbd which helps regulate it can’t be all that good for us. Don’t get me wrong I love strong frosty nugs but mother nature developed it for us over millions of years. If anything we should research how to grow normal marijuana/food quicker not stronger
Here's a couple links on UV Testing & Benefits - ua-cam.com/video/QRAU0ziyDpo/v-deo.html *Dutchman's Medical Marijuana* *Question/Statement* ; ..."U.V. light can increase resin, or oil production. Some resins contain more C.B.D. and very little T.H.C. So adding U.V. raises the oil production.Not always T.H.C., but U.V. does increase the potency through raised oil production. The oils shield the plant not the T.H.C. alone.".... *Response* ; ...."that is correct I have tested many strains and the majority of them only increase THC potency in fact I noticed the other cannabinoids dropped however we recently tested a Holy Grail in our room and it tested at 5% CBN 30% THC so the CBN went up 3% and a THC went up 5% so both can be affected however the majority of the energy from the plant seems to be directed towards THC and I believe that is because the plant is using the THC as sunscreen it's protecting itself so that it can live another day and not be Overexposed to the UV the killing the plants chance of survival because it needs to drop seeds at the end of its life cycle to carry on is lineage and it seems that THC is what is being used as the blocker like sunscreen Nature's sunscreen".... *AND* *John Berfelo* who actually owns a Mass Spectrometer, which allows him to accurately test for potency. ua-cam.com/video/0-VM_FJ_XpA/v-deo.html
I started growing with uvb a little under 1 year now. (2 harvests.) I’ve noticed a lot of changes and all for the better. Not only did my plant’s gain in potency, the taste, yields, and just the absolute look was much more than I expected. I wish I could post pictures on here. I can show you the difference. It’s like night and day.
@SEEK ONE UV should cause more resin, THC, CBD production. LED has 0 UV and 0 IR. HPS and CMH already have a littel UV since the're more natural broadband sources, so you'll see less improvement there.
Different strains act differently in my experience. Uv in early flower causes purpling. I believe Uv in LED lights is good in the last 20-25 days of flower to heavily increase your trichcomes
I've really been enjoying your channel from across the pond here in the US...please do keep it up. I've been recently considering some UV and IR supplementation strips but there is so little quantifiable data, just gut impressions and feelings. I feel that UV and IR are missing from many LEDs and the resulting bud I get from my Pacific Light Concepts grow is slightly less "dank" than from CMH, even if in other metrics it is superior like yield per watt, etc. However, saying something is missing and then finding an appropriate way to supplement it is more than just a simple question....if a human is missing a micronutrient you can't just throw some boron at them and expect them to thrive, it will be a slow process of supplementation through nutrition. How to dose UV and IR reliably and to the right degree, rather than just throwing some shit against the wall to see what sticks will be a really key implementation. Cheers!
Same here I have a MarsHydro TS 3000 and im getting good results with it but its lacking in the UV and IR spectrum, and im thinking of buying an extra Optic Led 2, just for the sake of adding the IV and UV-A mixture that goes in heavy with the Optic led, but im not even sure if this will benefit or hurt my plants
Hey Migro! Thank you for all your informative and helpful videos. You taught me alot. May you please do a head to head/review of reptile UVB t5 lights against reptile UVB screw in bulbs? It would be so cool to see the comparisons of UVB penetration, UVB mapping and overall efficiency. Again, thank you so much for everything you taught me.
Theres NEVER been weed even at 20% thc lol......ALL the little "test" kits that simply work by picking a nice frosty section of bud to throw into a container( usually baggie) and add chemicals to achieve the desired color range on the provided "chart" is 100% bullshit......% Numbers are pretty much the ONLY way to promote seed sales and boost business.....bullshit corporations like "high times" put on little displays like "cannabis cup" to confirm that the 27% claimed by the seed company is REAL and why it actually WON the "cup" ( good for a few years boosted sales)..... And let's face it 10-15$ per SEED is WAY TOO much $$$ ( for ANYTHING that grows upon this earth) but without the % SCAM they'd only be worth about 19-15$ for 100 or more lol ( just like everything else)..... STILL don't believe it?....then just go to ANY seed shop online ( OR in person) and see WHAT is selling the MOST .... Will it be lower or unlisted thc% strains?....or WILL the MOST popular BEST sellers ALWAYS be the highest ranked thc% strains?......i can guarantee you it makes little difference at THAT point because pretty much ALL the top strains are the same and none are consistently above 25% and MOST of the time below 20%...... Grow enough and you'll see first hand....
Brother you are the light king , is there any way that you could perform the UV test yourself for viewers to see ? That way no one has to rely on a thirty year old finding . Love your channel and videos , and have learned an astronomical amount of knowledge from you. Just thought I’d ask .
That would be cool! Do an actual side by side test in a legal state surely they aleady have i mean.. I see finishing globe being used by all the major medical facilities owned by various coal mining juggernauts.. they wouldn't drop a single cent on it without the results in hand.
Good topic....there is a UA-camr that has did a comparative test with gavita 1000 HPS vs black dog led vs kind k5 xl 1000.... the kind has a substantial amount of uv light.... the lab test showed more thc and terpenoids with the kind light, black dog was second and gavita last. However the gavita yielded a few ounces more than the kind led....
Great video as always Shane! Very interesting, although like you say that's a 30 year old experiment, would be nice to see it repeated with the new technology now available to us. Hope all is well with yourself and the rest of the Migro team!
Around my peers growing the general rule for our practices are using 10 % UVB2 of you primary strength.. ie 300w for 30% uvb2 and seems to be more effective on indicas Afghany Skunks kush etc Stativa seems more fickle and don't tend to like it much even seemingly to be damaged by it probably because of rainforest filtered light environments for alot of stativa strains .... no proof to show other then some beautiful results ... know your strain..... and if it comes from a dry high altitude regions. Like Himalayas etc it will most likely love that smash of UVB2... to me it's the phenotype vs genotype DNA vs environmental impact...... just saying
Definitely makes a diff... the two rooms that I have that have the UV are completely Crystal over the other two rooms are Frosty but definitely nowhere near as much
Good conversation although old I see. But has anyone ever tried,whenever you can… simply opening the tent doors to let natural sunlight pour in for a few hours a day or more if possible. I been doing this for a little while now and firmly believe they absolutely love that. I see it as no different than what green house growers do for supplemental/side lighting…
The problem has been the hostile attitude to almost all research efforts to show cannabis as anything but negative for at least 60 years, and as a consequence, very little research about changing yeilds of different cannabinoids or detailed research about different production methods. With legalisation sweeping over USA and Canada I'm sure that more work will be done but may not be made public given the huge sums of money involved. I'm happy with solacure flower power 1m 32w, along with Migro 200 with Gen 4 cobs (but not plus version). Was very tasty produce, but have nothing to compare too. I'd read about UVB8 receptor, and seemed to align with source material so just went for it. The germicidal/fungicidal/insecticidal properties of UVB are well known and for less than £100 and 32w for 3 hours a day that alone was worth it. If it also happens to up beneficials at the same time bonus! Something to consider. Bulb is about £50 to replace and lasts for 3 flowering sessions (then can be retired to veg area and used till it fails to fire, much longer time, maybe 4000h).
@@MIGROLIGHT 3 hours on in middle of 'day' started at 2 then upped it a bit, may have just been a coincidence but after a week, a very different looking plant, went from green to a very whitish looking frosty green.
How much UV watts did you add? Did you use the Migro UV light? Lastly, how much THC increase did you notice, was it too high THC/too little CBD, that it gave you paranoia every time you smoked? Thanks 🙏
right! these lights the best ive ever seen or used in twenty years of experience in this industry . hands down no arguments. got the first migro +600 it is a serious piece of kit ! thankyou shane the differences in potency would be fractional and can tell you this the proper enviroment and medium is way more beneficial
UV light a b c causes damage on the plant. old fashioned tanning lamps transmit a to c. utilized in a small amount, like 10 minutes twice a day at a good distance like 1 to 2 meters force the plant to develop defenses against damage and also utilize some of the light in photo synthesis. Resulting in stronger leaves, less fungus and more photo synthesis and more protection (thc etc).
all i know is that i burned the shite(notice the irish.... hehehe) outta some plants w/3days of 2 agromax uv/grow t5 bulbs.... about to try again w/my new LED rig, gonna use a timer and dose them all day..... lessee
I could see a difference in the color of my plants by adding UV lights. The plants had nice purple and pink color to them. I have no clue if they had more THC, but they looked nicer. I used a large reptile T5 light and a 30W UV COB light.
I’m using a Old Radiant8 CMH and my girls are loving its Light 💡 Output right now, their out in the Sun ☀️ in California 8 hours a day and then I give them a few hours a week under a 30 Watt LED for UV coloring 👍😉 Thanks Shane You Rock buddy!❤Your Channel
HE'S VERY SKEPTICAL.. YET HE IS SELLING HIS UVB LIGHTS TODAY. I like listening to the man while he's talking tech, but his agenda is capitalism. Also I think, all resins are increased, not just THC. I'm just trying to emulate the sun across the board. If anyone has accomplished this.. please respond. Thanks..Joe
In my 2 or 3 years of searching for all konds of info about growing weed, it seems to be the case that outdoor grown ( wih UV) is more penetrating and lasts longer, when smoked, than indoor with negligible UV. It doesn't necessarily increase THC %. There are other variables like soil quality, nutrients etc . I think I will have to do a comparison video with 2 plants of the same strain. They would be grown in the same conditions except UV A and B added for 1 and not the other Send them out for testing and do a subjective smoke report .
I use red blue spectrum all the time crystals in three weeks but I did a review with a red spectrum led only light and I didn’t see it like fweeks six but like you said it’s what you want out of the spectrum THC cbd or tempane so like this song say all of the lights hid cfl and led different wave of light different lights move different
I don't understand... the article is about UVA/UVB lights, all below 400nm length, but the spectrophotocolorimeter shows no light in the needed shorter wavelengths. Please help me understand what I'm missing.
I thought their were no studies done on Marijuana especially 30yrs ago.. and there was Marijuana with THC percentage of 25%-32% over 30yrs ago.. I think there needs to be a new study done.
I cured my multiple myeloma with high thc cannabis, never cared how cbd made me feel!. besides I would rather be awake for the rest of my days, when I use cbd all I do is sleep!.
Much of what is discussed is generally true, but it goes to both red and blue, hence the NASA studies. I personally from first hand experience found that what really changes is the trichome size itself. hps produces dense material, which has traditionally been desired. I myself used MH in the past throughout. I noticed immediate differences. Although my material was a bit more airy, the trichomes where incredibly large in contrast to hps material. I've now moved to full spectrum COBs(generally sold full spectrum 300w cobs) based on data and will pick up a BLUE heavy set(they are selling full spectrum with higher mixes of blue) to add as the size of the trichomes is a huge difference on the total resin produced; larger trichomes, more desired material. Until I do it first hand, I trust nothing. I see a huge push on QB lights. COBS and QBS are a growers war atm. i think it needs time in discussion. First hand, cross my heart, Blue UV makes trichomes larger.
When I was growing in my 3' by 3' tent I first used a 315 SunSystem CMH. It is known to put out UV. It also put out some infra-red. I stopped using it because of the infra red heat generated (during the summer), and it wasn't as efficient as my cob lights . I only now use it in the winter to keep it warm. Other wise you would have to use a space heater. I then started using the Migro 400. Way less heat problems. The only problem is that in the winter I'm forced to use the old CMH to keep the temperatures up. I DON'T NOTICE ANY DIFFERENCE IN POTENCY. THE ONLY DIFFERENCE IS THE CANNABIS SMELLS SWEETER WHEN GROWN WITH THE MIGRO 400.
So.your saying a pissy littoe 315 cmh light puts out considerably more heat then a 400w COB light? Wow I cant even stand under the cob lights in my bathroom their horrendously hot. I found cmh little crap ones like 315w to put out basically zero heat. Unless there was like 8 of them together. Even then it was cooler then 4 600w hps lights.
Owning a chain of indoor tanning salons for many many years I made it a point to learn everything I could about UVA, UVB, and UVC, along with skin care, and everything involved with the tanning process, etc. First of all, the florescent bulbs used in tanning beds, like all florescent bulbs, are glass. So if glass blocked or filtered out UV as you say, no one would ever get any tan and I'd have quickly been out of business. You go on to talk about someone adding 40 watt florescent bulbs to a grow and adding filters to filter out the UVA. Florescent bulbs are made of glass, so if as you say, glass filters out UV, why would they need to add filters to filter out anything? So I have to call obvious bull on that one. In another video you suggest wearing any kind of glasses with glass lens to protect your eyes from UV. This is absurd! Tanning goggles are akin to eye protection worn in welding. Glass provides ZERO protection from UV unless it's polarized like the windows in your car, and even then it only offers a slight filtering effect. If you rely on glass to protect your eyes from UV, you might want to invest in a white cane. Overexposure to UVA, UVB, or UVC WILL damage your eyes. Why do you think you need to wear eye protection in a tanning bed? Secondly, in indoor tanning you don't receive any UVC because, even though it is the deepest penetrating of the 3 types of UV, providing the deepest, darkest, and longest lasting tan, it is considered the most dangerous UV and can contribute to melanoma, a form of skin cancer that can be deadly. And yes, even though it isn't visible, the sun DOES deliver UVC. It's a fact! Besides, the jury is still out on the effects or any potential benefits of UV on grows. So sir, the information you are giving people is not accurate and even dangerous in some cases. I find it hard to believe you represent a LED manufacturing company (that just happens to sell UVB lights) with so many inaccurate statements. I can't believing what I'm hearing. You may want to check with your attorneys before opening your company up to potential libel suits. So unless you're trying to reduce the cannabis growing population, please get your facts straight.
UV light is divided into three bands-UVA, UVB, and UVC. UVB is critical to the development of THC. The potency of cannabis is dependent on the amount of UVB light it receives.
I used a horilux uva ,uvb 20 watt bulb at 4 20 min exposures at 2 ft for the last month of flowering. Every time my leaves get toasted. Not going to used it again. I might have seen a different for the first week only.
Ask urself this ... why does a plant produce trichomes?? One answer would be as a defence mechanism the brighter the direct sunt light (the more uv light) the plant recieves the more of a sunblock the plant will produce .. ie .. trichomes ... so to answer the question is a no brainer will uv increase the trichome production... i would think so my man.. happy growing everyone
WE look at uv A differently ---- to my way of thinking uv A in your lights just helps your seedlings get accustomed to "sun light" and it's not a shock for the plants to go outside in the sun (hardening off). To me I believe it's easier to go from a little(light) uv A to a lot(sun) uv A than from no uv A to a lot of uv A.
I killed 2 plats with UV-C. Left the light on for 3 hours. All the leaves that were exposed to the UV light died and all-new growth grew skewed and deformed for a couple days and then the plant was a write off as it was soo messed up
Yeah I realized this the next day. All the leaves became brittle within a couple of days and crumbled off just from a couple of hours of exposer to UV C. UV C is scary stuff!
How much UV should we be using? I have the California lightworks uvb light but not sure if i should run it all day, intermittently throughout the day or just s few hours?
Spent many years up in malana in the himalaya Making charas the plants around 3200m above sea level,always thought th insane resin production is a combination of the higher uv in the crystal clear air and the cold air at night
I appreciate you speaking on what actual research has shown. It's so troublesome because cannabis has such a lack of research but from first hand experience it appears with cannabis the trichomes and oils are presented as a protection against UV light and having uv present does atleast visually appear to promote for trichome production. Any plans on doing a side by side grow with the same phenotype with one getting UV supplementation?
@@TheMusicHeals.kjhjhhg 0 references are great. I haven't seen a side by side but I have seen an IR only grow that was dumb, slow and pathetic but it did grow so its at least capable of some contribution and if they want to put a couple in, go for it.
WORK UNTIL I DIE Remodeling and repair we've a black light in our room give me a month I'll let you know how she does ! Supposed to increase thc volume?
Thank you SO much for cutting through all the BS surrounding all the "bro science" in this pursuit. Your contribution has me looking for an excuse to buy your lights to subsidize more research. It'll be money well spent.
a constant supply of UV like the CMH provides is not necessarily what you want for potency but it can help increase the total count of trichs but this won't increase potency because THC absorbs the UV light like sunscreen and degrades itself in the process.......that being said it has come to be known that what you want to do is expose them to the critical wavelengths during the 3 hour peak of the daylight period and use a much more intense UV light source than what the CMH or even the Reptile lights provide..they are not enough power......you need the kind of uv power that will destroy them in 2 hours of 100% duty cycle exposure ...something like 75%UVB 25%UVA ..so that is about all the lamp produces ...and then run that with a cycle timer at 15 on 15 off and tweek it until you get it dialed down so it doesn't hurt the plant at all.....but it still gets exposed to a high level of it for the peak 3-5 hours ....simulating the effects of high altitude environment in nature such as the KUSH mountains ......or equatorial regions also have this effect because of the earth's atmosphere's ability to filter UV .....all that being said keep in mind some genetics are not capable of responding as well as others and some strands are already responding as well as they can without stimulation and then some strains will respond well to exposure and reach a genetic potential of producing more thc than it could have without the extra push........a lot of this may also have to do with the nutrients as well as the wet dry cycle.....things like chitin/chitinase or even having enough sulfur to produce the oils can all play a large role in plant secretions. ........ just remember little indian dudes been growing kush at high altitude for at least 6k years and thats why indica can kick some ass.....its not the closet growers of the past 50 years basically ....you wanna hit em with a powerful ass UV lamp but only for a second so the plant is left to freak the total f&^) out about it but it didn't actually hurt the plant .....its all about the hormonal hormonal response without the harmful effects of constant bombardment of such powerful photons ......counter intuitive lessons for days in this one folks.......more power with the bulbs and more of them to eliminate shadowing but shorten exposure time down to eliminate damaging DNA i pulled this from amazon here in USA ....Agromax is the latest craze for the UV market here....much love and enjoy!!! ((((AgroMax Pure UV is the industry's most advanced supplemental ultraviolet grow lamp, with 15x more power than other types of UV lamps. Supplemental UV-B light can have desirable effects in the phenolic compounds, flavonoid pigments, resins, oils, etc. of many plants. Using advanced phosphors and highly-specialized UV transmitting glass, Pure UV lamps emit a 3:1 ratio of UV-B to UV-A with a slight amount of visible light to produce such sought after effects through a plants own natural processes and without the use of chemicals. Please note: reaction to supplemental UV can vary among plant strains. Applied UV levels will be affected by; 1) number of lamps, 2) distance, and 3) efficiency of the fixture power supply & reflector. WARNING: Overexposure to UV light can be harmful to humans and plants. Proper protective eye-wear and long-sleeve clothing is necessary when working with Pure UV lamps. When supplementing gardens with Pure UV lamps, it is best to begin with the lamp placed further away from the plants and to run it for shorter periods)))))
I prefer it in my grow room for two reasons, to sterilize the grow area of mold spores and such, and to help rid the area of pests. I swear the first time I noticed the benefits of uv in a grow area was when I purchased an Osram Zelion HL fixture... The UV in that light is extremely powerful and the fungus gnat problem that I was encountering at the time was absent in the tent with the Osram Zelion. The gnats hated that intense uv spectrum almost as much as my eyes did. I must add that I had four tents full of plants growing at the time...
Ditch the UV. Use colloidal silver in the nutrient solution to control mold. Light output should peak at around 435 to 450nm in the blue spectrum and 600 to 660nm in the red spectrum
@@melvin4681 Why add stuff into the nutrient solution when you can easily do it with UV? Not only it works against pests, but also increases the THC, flavors and aroma. It's in the natural sunlight. Using UV is a win-win-win situation.

You will not lose CBD. CBG turns into THCa or CBDa and primarily genetics will be deciding how much cannabinoid percentage results in a particular strain although some outside influences can better or worse the condition. CBD is also formed much earlier than THC they have found in studies of CBD is present even in vegetative growth. So UV light should not have the effect of diminishing CBD for the increase of THC. UV light should result in a increase in both cannabinoids. If any at all. Also they used same plants.. So was it a cut or by seed if by seed then no control. We know a lot more about cannabis now then in 1988 I'm also finding the THC percentage hard to believe way back then when we barely have 32 percenters now.
sorry if i don't get anything information at this video, because my English is bad So i have some questions : - Do plants need uv lamps, and how much is enough (for CFL bulbs, I have a black light uv a 40w) - Should use in what period? - Can be used from beginning to end of a tree's life cycle? Please help !!!
@@MIGROLIGHT Surely the Electric Sky 300 will be up there on the charts ? Would be great to compare to Migro 200 as I think they both do a 2x4 ? Shane, I think you should do a Migro 200 Veg, which would be a bit cheaper than buying two Migro 100 veg. ;)
Some good info..and thanks for being brave enuff to do this... one thing tho you cant sacrifice cbd for thc...thats already predetermined by the genetics..you can only max out the plant to wat ever its genetics allowe be that its maximum thc and cbd..but you cant lower cbd if you up thc..you can alter the outcome of the ratios but ther will always be a maximum amount preprogramed already in the plant...but if I had perfectly replicated the environment to get near enuff the best I could out of a plant and for example I got a ratio of 15% thc and 5% cbd by me further bettering that environment to its peak and upping the uv light content, yes I might be able to max out my thc to the predetermined genetic peak , which in this example was say 20%..so we would get a plant that was now producing 20%thc but the cbd would not lower and would still remain at its predetermined max wich in our example was 5% and it would stay at 5%. I hope you was able to understand wat im saying..I just wanted you to be able to give the best info..as you aways do...thanks
I use 2 ts 1000 along with a wish square blue red light in between in my 4x4. I've noticed benefits from adding the blurple like for 15 at startup of light cycle and 45 at the end. while in flowering, in 12 n 12. I'm running ethos photos, but I wondering the same lighting for autos how they would do.
One would assume that with cannabis being legalized in growing numbers of states that more concrete evidence and research would come out in regards to what does and does not work. Instead it has just increased hype and rumor, and recited marketing claims (look at all the nutrients out there!!) I grow more than cannabis, and I love seeing well documented tests as it can be applied to all plants. Can't wait to see what you come up with.
I want to know if UV effects the Bud to Leaf Ratio. My indoor does Not have UV and its a Nice cola with few leaf. Outside the same Pheno has ton of leaf. I think its from the UV, Anybody know about this?
Hey I’d like to see you do a test on Metal Halide 6000 k bulb like a supernova bulb ! You never see people use metal halides because of the myth that they don’t do well ! I have better luck with metal halide super nova bulbs and you could test a metal halide 3000 k bulb I use with the super nova and I’ll put against anything or any light bulb on market! The brand of bulb in 3000 k is called Agro Sun! Because I don’t like using anything else but super nova bulbs! That would be a test worth doing!
I had the same experience with 10.0 reptile bulbs (added like 60w Mer m2 at 1.5 feet) growing og#18 under blurple leds. I had already grown og18 under hps and under blurple leds without uvb supplement. I push the og18 to 84 days flower for best smell and complex effect. Basically with the uvb supplement a bong hit of 0.12g would affect me intensely for 6 hours, VS standard bong hits of 0.2g of other strains would affect me intensely for 10-90 minutes... Also 1 friend got a psychosis from a bong hit and most friends (daily stoner!) thought they needed to go to hospital. I measured a consistent increase in my bpm from approx 60 to 110 for 5-20 minutes after a bong hit. I know it's very subjective but in my experience the difference in complexity/depth of taste and effect was incredible. 0.5g would last me a day, compared to anything else where I would make 5g disappear in a day... Also: with uvb the og18 effect seemed to have no ceiling (I had some fun and wierd experiences trying to find that ceiling - an I'm the type that takes a fat dab before/for breakfast). After spending 10 years trying to find bud with a comparable taste/effect I gave up as nothing comes close... So I started a garden again and just got the migro310 this week! Will report back in 2-3 months if it made my current day 35f Bubba kush 'express itself'/'release its poison' :) BTW my og18 grown under uvb I could smell 1g from 100meters no joke. My current non-uvb flowers I need to stick my nose in the bag to get some smell LOL (yes I harvest late and dry slow and cure to 62% etc)
So basically my last uvb supplemented grow literally sent my best bro to psychiatric prison for nearly a year (he was very stable and healthy and a very sober smart student doing plenty of sport aswell before that psychosis inducing bong hit), it made me experience 'hearing my thoughts echo through my head like it was someone else speaking'... WTF??? An I used to grow shrooms so I'm not someone to exaggerate effects: usually store bought weed to me is very mild and just calms/slows me down a bit and strains lack personality. Try uvb supplement and stay safe...
Noticed difference with light had uvb that plants under ha d ore trichs and lots of trichs on the sugar leaves and a light without uv but with far red high efficiency light that the trichs production was lower

farmers cultivate weed in mountainous regions for a reason. different height levels from sea level produces different qualities of plant like high medium and low grade. the best stuff always comes nearest the top fields where uv levels are higher. the grade of soil plays a factor in this also.
in short yes uv light will induce a sexually frustrated female plant into producing more resin for two reasons 1 in the hope of capturing a little bit of pollen so she can reproduce and 2 the extra resin acts as a sun screen to protect the plant from higher radiation levels in turn raising the thc levels even more. honestly uv light works
Colin Scott what do you use for lighting for the uv?
Yeah i got the mars hydro ts3000 quantum board with 1000 leds and two meanwell drivers of which both drivers have adjustable screws to control the uv and white leds independently ( you could crank the leds down and the uv up).....I'm thinking maybe for THIS very reason.....
@@frankmoser6251 wow, when did they add this feature? Must be a ts3000 thing
@@frankmoser6251 the ts3000 has IR, as it's being sold right now
Yeah yeah IR is what i meant.....SAME thing as uv in late bloom......at least that's what I've read.....I'm brand new to the indoor gardening game so having one of the BEST quantum boards on the market was probably overkill.....but i ALSO have the healthiest looking starters after just 29 days....so thick you can't even see the dirt in the buckets anymore.....barely ANY stretch and I'll have to trim them just to water em........BUT I'll guarantee you it works very WELL for the 450$ it cost
The reason why adding UV light increases the thc percentage is very simple. UV is actually a harmfull wavelength for plants, plants feels it's presence and as a response the start making more resin for protection. The resin protects the plant structure.
You nailed it.. Cannabis developed their unique trichome structure and chemical compounds to help filter out UV light from hitting the seed pods which could potentially damage the seed and it would seem THC plays a big part in that protection.
Not to mention the oftentimes bitter taste, extreme stickiness and disorienting effects of that chemical concoction in which is unpalatable and undesirable to most animals (aside from us of course).
It makes you wonder if enacting other common threats that they would naturally encounter might increase other compounds as well.
@@EnhancedCognition other common threats....interesting thought actually...hmmm.....
Oh I know one! Try having a cow eat it!
@@EnhancedCognition The biggest threat is when the cow eats all of it! So we should try that first;)
I randomly threaten to cut them down with a machete works every time scares the THC right to the surface
I play endless horror movie sound tracks in the grow room.. scares the fuck out of the plants ;)
My understanding is CBD binds with receptors in the body more easily than THC therefore consuming buds with high THC & CBD is counter intuitive. Higher CBD reduces THC uptake in the body. My medicinal preference is for high THC (up to 20%) low CBD flowers. Lower CBD to THC ratio means I need to consume less for the desired medicinal effect. The less I consume the healthier (and cheaper) it is for me. That's my opinion based on my own knowledge and consumption.
I hear what you're saying. But the entourage effect and a lot of research would say that CBD actually increases the effects of THC at the right ratios. My personal experience mixing and vaping thc and cbd flower together has made me think that it's probably right. It really does work that way to an extent, give it a shot though, ymmv. We all experience cannabinoids differently
If marijuana could cure schizophrenia the amount of money spent would never go in to r&d to devolve such strong weed to save us money and make it better for us. If you think about it thc is literally the psychoactive part so by eliminating the cbd which helps regulate it can’t be all that good for us. Don’t get me wrong I love strong frosty nugs but mother nature developed it for us over millions of years. If anything we should research how to grow normal marijuana/food quicker not stronger

*Dutchman's Medical Marijuana*
*Question/Statement* ; ..."U.V. light can increase resin, or oil production. Some resins contain more C.B.D. and very little T.H.C. So adding U.V. raises the oil production.Not always T.H.C., but U.V. does increase the potency through raised oil production. The oils shield the plant not the T.H.C. alone."....
*Response* ; ...."that is correct I have tested many strains and the majority of them only increase THC potency in fact I noticed the other cannabinoids dropped however we recently tested a Holy Grail in our room and it tested at 5% CBN 30% THC so the CBN went up 3% and a THC went up 5% so both can be affected however the majority of the energy from the plant seems to be directed towards THC and I believe that is because the plant is using the THC as sunscreen it's protecting itself so that it can live another day and not be Overexposed to the UV the killing the plants chance of survival because it needs to drop seeds at the end of its life cycle to carry on is lineage and it seems that THC is what is being used as the blocker like sunscreen Nature's sunscreen"....

I started growing with uvb a little under 1 year now. (2 harvests.) I’ve noticed a lot of changes and all for the better. Not only did my plant’s gain in potency, the taste, yields, and just the absolute look was much more than I expected. I wish I could post pictures on here. I can show you the difference. It’s like night and day.
Bo Timms got an instagram where you post the differences?
@@botimms3681 What kind light were u augmenting?
I think it's possible UV causes the biggest change in LED setups.
@SEEK ONE UV should cause more resin, THC, CBD production. LED has 0 UV and 0 IR. HPS and CMH already have a littel UV since the're more natural broadband sources, so you'll see less improvement there.
Different strains act differently in my experience. Uv in early flower causes purpling. I believe Uv in LED lights is good in the last 20-25 days of flower to heavily increase your trichcomes
What makes you say that time period ?? What percentage would you think ?
University research has shown no beneficial effects of uv on cannabinoid synthesis
I've really been enjoying your channel from across the pond here in the US...please do keep it up. I've been recently considering some UV and IR supplementation strips but there is so little quantifiable data, just gut impressions and feelings.
I feel that UV and IR are missing from many LEDs and the resulting bud I get from my Pacific Light Concepts grow is slightly less "dank" than from CMH, even if in other metrics it is superior like yield per watt, etc.
However, saying something is missing and then finding an appropriate way to supplement it is more than just a simple question....if a human is missing a micronutrient you can't just throw some boron at them and expect them to thrive, it will be a slow process of supplementation through nutrition. How to dose UV and IR reliably and to the right degree, rather than just throwing some shit against the wall to see what sticks will be a really key implementation.
Cheers!
Which PLC light are you rocking? I think the ultimate light setup would be a mixture of CMH and COB IMO
Same here I have a MarsHydro TS 3000 and im getting good results with it but its lacking in the UV and IR spectrum, and im thinking of buying an extra Optic Led 2, just for the sake of adding the IV and UV-A mixture that goes in heavy with the Optic led, but im not even sure if this will benefit or hurt my plants
@@DiazShitAndStuff HLG and rapidled have better deals for just IR and uva btw
Hey Migro! Thank you for all your informative and helpful videos. You taught me alot. May you please do a head to head/review of reptile UVB t5 lights against reptile UVB screw in bulbs? It would be so cool to see the comparisons of UVB penetration, UVB mapping and overall efficiency. Again, thank you so much for everything you taught me.
yeah right thats all u bro....LOL
i used too much UV the first time i experimented. I had a huge increase of THC. the plants we're pretty bleached out but they finished well.
You made a small mistake regarding the concentration of thc. It is mg/g. So 2.5 to 3.2%. Not 25 to 32.
6:50
Thanks👍
dont think there was weed with over 30 % back in 1980 ^^
@@dschungo yeah as far as I know 30% THC is quite a recent advancement in cannabis breeding. Even 20% probably wasn't available in the 80s.
@Joseph No need to be triggered, it was a mistake.
Theres NEVER been weed even at 20% thc lol......ALL the little "test" kits that simply work by picking a nice frosty section of bud to throw into a container( usually baggie) and add chemicals to achieve the desired color range on the provided "chart" is 100% bullshit......% Numbers are pretty much the ONLY way to promote seed sales and boost business.....bullshit corporations like "high times" put on little displays like "cannabis cup" to confirm that the 27% claimed by the seed company is REAL and why it actually WON the "cup" ( good for a few years boosted sales)..... And let's face it 10-15$ per SEED is WAY TOO much $$$ ( for ANYTHING that grows upon this earth) but without the % SCAM they'd only be worth about 19-15$ for 100 or more lol ( just like everything else)..... STILL don't believe it?....then just go to ANY seed shop online ( OR in person) and see WHAT is selling the MOST .... Will it be lower or unlisted thc% strains?....or WILL the MOST popular BEST sellers ALWAYS be the highest ranked thc% strains?......i can guarantee you it makes little difference at THAT point because pretty much ALL the top strains are the same and none are consistently above 25% and MOST of the time below 20%...... Grow enough and you'll see first hand....
Brother you are the light king , is there any way that you could perform the UV test yourself for viewers to see ? That way no one has to rely on a thirty year old finding . Love your channel and videos , and have learned an astronomical amount of knowledge from you. Just thought I’d ask .
That would be cool! Do an actual side by side test in a legal state surely they aleady have i mean.. I see finishing globe being used by all the major medical facilities owned by various coal mining juggernauts.. they wouldn't drop a single cent on it without the results in hand.
Good topic....there is a UA-camr that has did a comparative test with gavita 1000 HPS vs black dog led vs kind k5 xl 1000.... the kind has a substantial amount of uv light.... the lab test showed more thc and terpenoids with the kind light, black dog was second and gavita last. However the gavita yielded a few ounces more than the kind led....

Great video as always Shane! Very interesting, although like you say that's a 30 year old experiment, would be nice to see it repeated with the new technology now available to us. Hope all is well with yourself and the rest of the Migro team!
Bugbee vids cover this
Around my peers growing the general rule for our practices are using 10 % UVB2 of you primary strength.. ie 300w for 30% uvb2 and seems to be more effective on indicas Afghany Skunks kush etc Stativa seems more fickle and don't tend to like it much even seemingly to be damaged by it probably because of rainforest filtered light environments for alot of stativa strains .... no proof to show other then some beautiful results ... know your strain..... and if it comes from a dry high altitude regions. Like Himalayas etc it will most likely love that smash of UVB2... to me it's the phenotype vs genotype DNA vs environmental impact...... just saying
As always you have the best topics with a wealth of information when it comes to lighting. Thank you for sharing, hope you continue with this topic.
Definitely makes a diff... the two rooms that I have that have the UV are completely Crystal over the other two rooms are Frosty but definitely nowhere near as much
What bulbs for UVB do you use 5.0 10.0 15.0 or 20.0 ? Also, when do you start using them in your cycle? How many hours a day?
Good conversation although old I see. But has anyone ever tried,whenever you can… simply opening the tent doors to let natural sunlight pour in for a few hours a day or more if possible. I been doing this for a little while now and firmly believe they absolutely love that. I see it as no different than what green house growers do for supplemental/side lighting…
Works very nice Thank you!
The problem has been the hostile attitude to almost all research efforts to show cannabis as anything but negative for at least 60 years, and as a consequence, very little research about changing yeilds of different cannabinoids or detailed research about different production methods. With legalisation sweeping over USA and Canada I'm sure that more work will be done but may not be made public given the huge sums of money involved.
I'm happy with solacure flower power 1m 32w, along with Migro 200 with Gen 4 cobs (but not plus version). Was very tasty produce, but have nothing to compare too. I'd read about UVB8 receptor, and seemed to align with source material so just went for it.
The germicidal/fungicidal/insecticidal properties of UVB are well known and for less than £100 and 32w for 3 hours a day that alone was worth it. If it also happens to up beneficials at the same time bonus!
Something to consider. Bulb is about £50 to replace and lasts for 3 flowering sessions (then can be retired to veg area and used till it fails to fire, much longer time, maybe 4000h).
Thanks for the information. what lighting schedule do you use with the Solacure?
@@MIGROLIGHT 3 hours on in middle of 'day' started at 2 then upped it a bit, may have just been a coincidence but after a week, a very different looking plant, went from green to a very whitish looking frosty green.
🥴 Yeah it was my goal and it does work big time, 🥴👍
How much UV watts did you add? Did you use the Migro UV light?
Lastly, how much THC increase did you notice, was it too high THC/too little CBD, that it gave you paranoia every time you smoked?
Thanks 🙏
right! these lights the best ive ever seen or used in twenty years of experience in this industry . hands down no arguments. got the first migro +600 it is a serious piece of kit ! thankyou shane
the differences in potency would be fractional and can tell you this the proper enviroment and medium is way more beneficial
stress, not optimal environments, create the best flower
how long and often should i keep plants under uv to stay safe
This reminds me of when I was a teenager and I attempted to grow a plant with a blacklight & window sill
How did it turn out?
what should be the percentage of UV A and UV B in grow lights ?
Dude... You are the light guy! You do and film the experiment on it. Fuck yeah
UV light a b c causes damage on the plant. old fashioned tanning lamps transmit a to c.
utilized in a small amount, like 10 minutes twice a day at a good distance like 1 to 2 meters force the plant to develop defenses against damage and also utilize some of the light in photo synthesis. Resulting in stronger leaves, less fungus and more photo synthesis and more protection (thc etc).
I use a "10k finishing bulb" to achieve 6-7% more resin production.
Which ones? I got 4 from agromax and I'm seeing major results in one day
@@Rabbit.760 SunPulse 600w 10K $50 on ebay I run it at 300w in a 4x4 during ripening. For flowering I use around 750w of vanderlife leds.
all i know is that i burned the shite(notice the irish.... hehehe) outta some plants w/3days of 2 agromax uv/grow t5 bulbs.... about to try again w/my new LED rig, gonna use a timer and dose them all day..... lessee
hows the agromax working for you ?
Great vid. I add two reptile uvb cfl 25w in the fruiting stage for bout 15years they work great
I would love if you did another video on the other side of the spectrum, far red/infrared.
Id love to see a comparison led grow , one side high temps, other side lower temps + infra red; but same leaf temp on both sides.
Look up Emerson effect. Pretty interesting info on far red
UVC light can also be used to kill germs mold fungus bugs but it's really bad for you so when you use it you should not be within its range
Not for plants either
Thank you for data! Seriously helpful in a market with so many products.
I could see a difference in the color of my plants by adding UV lights. The plants had nice purple and pink color to them. I have no clue if they had more THC, but they looked nicer. I used a large reptile T5 light and a 30W UV COB light.
Could you please tell me the hanging height? And what exact light did you use, how many watts. UVA/UVB percentage etc.?
I’m using a Old Radiant8 CMH and my girls are loving its Light 💡 Output right now, their out in the Sun ☀️ in California 8 hours a day and then I give them a few hours a week under a 30 Watt LED for UV coloring 👍😉 Thanks Shane You Rock buddy!❤Your Channel

What about uva? You talked a lot about uvb
HE'S VERY SKEPTICAL.. YET HE IS SELLING HIS UVB LIGHTS TODAY. I like listening to the man while he's talking tech, but his agenda is capitalism. Also I think, all resins are increased, not just THC. I'm just trying to emulate the sun across the board. If anyone has accomplished this.. please respond. Thanks..Joe
In my 2 or 3 years of searching for all konds of info about growing weed, it seems to be the case that outdoor grown ( wih UV) is more penetrating and lasts longer, when smoked, than indoor with negligible UV. It doesn't necessarily increase THC %. There are other variables like soil quality, nutrients etc . I think I will have to do a comparison video with 2 plants of the same strain. They would be grown in the same conditions except UV A and B added for 1 and not the other Send them out for testing and do a subjective smoke report .
Right on Brother Shane !!! You are just the man for this mission .. good luck to you .. will follow all the way ..... Dennis
I use red blue spectrum all the time crystals in three weeks but I did a review with a red spectrum led only light and I didn’t see it like fweeks six but like you said it’s what you want out of the spectrum THC cbd or tempane so like this song say all of the lights hid cfl and led different wave of light different lights move different
Can't wait to see the results of the MIGRO 100+ vs MIGRO Veg
Thank you for another incredibly informative video
yes well done,the actual showing of the grafts & paperwork,very helpful,good job
I don't understand... the article is about UVA/UVB lights, all below 400nm length, but the spectrophotocolorimeter shows no light in the needed shorter wavelengths. Please help me understand what I'm missing.
john lydon? like.. from the sex pistols and P.I.L? no way.
I thought their were no studies done on Marijuana especially 30yrs ago.. and there was Marijuana with THC percentage of 25%-32% over 30yrs ago.. I think there needs to be a new study done.
There is plenty of ‘evidence’ from growers that UV is effective. It would be nice to see more published data (controlled study) though.
I cured my multiple myeloma with high thc cannabis, never cared how cbd made me feel!. besides I would rather be awake for the rest of my days, when I use cbd all I do is sleep!.
My wife also used cannabis and cured myeloma. Do you have any strains to recommend or any advice on what worked for you?
Much of what is discussed is generally true, but it goes to both red and blue, hence the NASA studies. I personally from first hand experience found that what really changes is the trichome size itself. hps produces dense material, which has traditionally been desired. I myself used MH in the past throughout. I noticed immediate differences. Although my material was a bit more airy, the trichomes where incredibly large in contrast to hps material. I've now moved to full spectrum COBs(generally sold full spectrum 300w cobs) based on data and will pick up a BLUE heavy set(they are selling full spectrum with higher mixes of blue) to add as the size of the trichomes is a huge difference on the total resin produced; larger trichomes, more desired material. Until I do it first hand, I trust nothing. I see a huge push on QB lights. COBS and QBS are a growers war atm. i think it needs time in discussion. First hand, cross my heart, Blue UV makes trichomes larger.
When I was growing in my 3' by 3' tent I first used a 315 SunSystem CMH. It is known to put out UV. It also put out some infra-red. I stopped using it because of the infra red heat generated (during the summer), and it wasn't as efficient as my cob lights . I only now use it in the winter to keep it warm. Other wise you would have to use a space heater.
I then started using the Migro 400. Way less heat problems. The only problem is that in the winter I'm forced to use the old CMH to keep the temperatures up. I DON'T NOTICE ANY DIFFERENCE IN POTENCY. THE ONLY DIFFERENCE IS THE CANNABIS SMELLS SWEETER WHEN GROWN WITH THE MIGRO 400.
So.your saying a pissy littoe 315 cmh light puts out considerably more heat then a 400w COB light? Wow I cant even stand under the cob lights in my bathroom their horrendously hot. I found cmh little crap ones like 315w to put out basically zero heat. Unless there was like 8 of them together. Even then it was cooler then 4 600w hps lights.
Owning a chain of indoor tanning salons for many many years I made it a point to learn everything I could about UVA, UVB, and UVC, along with skin care, and everything involved with the tanning process, etc. First of all, the florescent bulbs used in tanning beds, like all florescent bulbs, are glass. So if glass blocked or filtered out UV as you say, no one would ever get any tan and I'd have quickly been out of business. You go on to talk about someone adding 40 watt florescent bulbs to a grow and adding filters to filter out the UVA. Florescent bulbs are made of glass, so if as you say, glass filters out UV, why would they need to add filters to filter out anything? So I have to call obvious bull on that one. In another video you suggest wearing any kind of glasses with glass lens to protect your eyes from UV. This is absurd! Tanning goggles are akin to eye protection worn in welding. Glass provides ZERO protection from UV unless it's polarized like the windows in your car, and even then it only offers a slight filtering effect. If you rely on glass to protect your eyes from UV, you might want to invest in a white cane. Overexposure to UVA, UVB, or UVC WILL damage your eyes. Why do you think you need to wear eye protection in a tanning bed? Secondly, in indoor tanning you don't receive any UVC because, even though it is the deepest penetrating of the 3 types of UV, providing the deepest, darkest, and longest lasting tan, it is considered the most dangerous UV and can contribute to melanoma, a form of skin cancer that can be deadly. And yes, even though it isn't visible, the sun DOES deliver UVC. It's a fact! Besides, the jury is still out on the effects or any potential benefits of UV on grows. So sir, the information you are giving people is not accurate and even dangerous in some cases. I find it hard to believe you represent a LED manufacturing company (that just happens to sell UVB lights) with so many inaccurate statements. I can't believing what I'm hearing. You may want to check with your attorneys before opening your company up to potential libel suits. So unless you're trying to reduce the cannabis growing population, please get your facts straight.
UV light is divided into three bands-UVA, UVB, and UVC. UVB is
critical to the development of THC. The potency of cannabis is dependent on the
amount of UVB light it receives.

I used a horilux uva ,uvb 20 watt bulb at 4 20 min exposures at 2 ft for the last month of flowering. Every time my leaves get toasted. Not going to used it again. I might have seen a different for the first week only.
Ask urself this ... why does a plant produce trichomes?? One answer would be as a defence mechanism the brighter the direct sunt light (the more uv light) the plant recieves the more of a sunblock the plant will produce .. ie .. trichomes ... so to answer the question is a no brainer will uv increase the trichome production... i would think so my man.. happy growing everyone
Its also to deture bugs and herbivores. It might explain results from defoliation. Plant is trying to prevent getting eaten.
The hell is thc?
WE look at uv A differently ---- to my way of thinking uv A in your lights just helps your seedlings get accustomed to "sun light" and it's not a shock for the plants to go outside in the sun (hardening off). To me I believe it's easier to go from a little(light) uv A to a lot(sun) uv A than from no uv A to a lot of uv A.
I killed 2 plats with UV-C. Left the light on for 3 hours.
All the leaves that were exposed to the UV light died and all-new growth grew skewed and deformed for a couple days and then the plant was a write off as it was soo messed up
It's uvb that is to be used not uvc.
Yeah I realized this the next day. All the leaves became brittle within a couple of days and crumbled off just from a couple of hours of exposer to UV C.
UV C is scary stuff!
Ditto. A little 14 watt bulb.

How much UV should we be using? I have the California lightworks uvb light but not sure if i should run it all day, intermittently throughout the day or just s few hours?
no more then 2 hours a day and during mid light cycle
Spent many years up in malana in the himalaya
Making charas the plants around 3200m above sea level,always thought th insane resin production is a combination of the higher uv in the crystal clear air and the cold air at night
Any chance u can test a biowave?
I know it’s not a light. Looks like something out of a old sci-fi movie but they’re making big claims
Is that ur attempt at being smart?
3:50 where did you hear that BS?
There's plenty of UV that comes from both LED and fluorescent why do you think you fake tan with them
I appreciate you speaking on what actual research has shown. It's so troublesome because cannabis has such a lack of research but from first hand experience it appears with cannabis the trichomes and oils are presented as a protection against UV light and having uv present does atleast visually appear to promote for trichome production. Any plans on doing a side by side grow with the same phenotype with one getting UV supplementation?
@@TheMusicHeals.kjhjhhg 0 references are great. I haven't seen a side by side but I have seen an IR only grow that was dumb, slow and pathetic but it did grow so its at least capable of some contribution and if they want to put a couple in, go for it.
Please run your own test and prove this true or false then I can’t wait

Why do my wheatgrass start to become yellow after two inches of growth? Any answers anyone?
THC in non-UVB= 25%
TCH in supplimental UVB= 32%
That equals a 28% increase in THC? My studies have shown a 7% increase. Anyways, good video though.
a constant supply of UV like the CMH provides is not necessarily what you want for potency but it can help increase the total count of trichs but this won't increase potency because THC absorbs the UV light like sunscreen and degrades itself in the process.......that being said it has come to be known that what you want to do is expose them to the critical wavelengths during the 3 hour peak of the daylight period and use a much more intense UV light source than what the CMH or even the Reptile lights provide..they are not enough power......you need the kind of uv power that will destroy them in 2 hours of 100% duty cycle exposure ...something like 75%UVB 25%UVA ..so that is about all the lamp produces ...and then run that with a cycle timer at 15 on 15 off and tweek it until you get it dialed down so it doesn't hurt the plant at all.....but it still gets exposed to a high level of it for the peak 3-5 hours ....simulating the effects of high altitude environment in nature such as the KUSH mountains ......or equatorial regions also have this effect because of the earth's atmosphere's ability to filter UV .....all that being said keep in mind some genetics are not capable of responding as well as others and some strands are already responding as well as they can without stimulation and then some strains will respond well to exposure and reach a genetic potential of producing more thc than it could have without the extra push........a lot of this may also have to do with the nutrients as well as the wet dry cycle.....things like chitin/chitinase or even having enough sulfur to produce the oils can all play a large role in plant secretions. ........
just remember little indian dudes been growing kush at high altitude for at least 6k years and thats why indica can kick some ass.....its not the closet growers of the past 50 years
basically ....you wanna hit em with a powerful ass UV lamp but only for a second so the plant is left to freak the total f&^) out about it but it didn't actually hurt the plant .....its all about the hormonal hormonal response without the harmful effects of constant bombardment of such powerful photons ......counter intuitive lessons for days in this one folks.......more power with the bulbs and more of them to eliminate shadowing but shorten exposure time down to eliminate damaging DNA
i pulled this from amazon here in USA ....Agromax is the latest craze for the UV market here....much love and enjoy!!!
((((AgroMax Pure UV is the industry's most advanced supplemental ultraviolet grow lamp, with 15x more power than other types of UV lamps. Supplemental UV-B light can have desirable effects in the phenolic compounds, flavonoid pigments, resins, oils, etc. of many plants. Using advanced phosphors and highly-specialized UV transmitting glass, Pure UV lamps emit a 3:1 ratio of UV-B to UV-A with a slight amount of visible light to produce such sought after effects through a plants own natural processes and without the use of chemicals.
Please note: reaction to supplemental UV can vary among plant strains. Applied UV levels will be affected by; 1) number of lamps, 2) distance, and 3) efficiency of the fixture power supply & reflector.
WARNING: Overexposure to UV light can be harmful to humans and plants. Proper protective eye-wear and long-sleeve clothing is necessary when working with Pure UV lamps. When supplementing gardens with Pure UV lamps, it is best to begin with the lamp placed further away from the plants and to run it for shorter periods)))))
I prefer it in my grow room for two reasons, to sterilize the grow area of mold spores and such, and to help rid the area of pests.
I swear the first time I noticed the benefits of uv in a grow area was when I purchased an Osram Zelion HL fixture... The UV in that light is extremely powerful and the fungus gnat problem that I was encountering at the time was absent in the tent with the Osram Zelion. The gnats hated that intense uv spectrum almost as much as my eyes did. I must add that I had four tents full of plants growing at the time...
Ditch the UV. Use colloidal silver in the nutrient solution to control mold. Light output should peak at around 435 to 450nm in the blue spectrum and 600 to 660nm in the red spectrum
@@melvin4681 Why add stuff into the nutrient solution when you can easily do it with UV? Not only it works against pests, but also increases the THC, flavors and aroma. It's in the natural sunlight. Using UV is a win-win-win situation.

Bruh, why is most of indoor gardening focused on drugs... I want tips on how to grow vulnerable veggies plants, not fricking FBI on my tail. *smh*
Hey,
You will like what we have coming up soon so, stay tuned.
Thanks.
mammoth has this uv bar that i saw at my local garden store; wish i could find a reveiw on it!
I was lookin at the gavita uvr bar site is 2021 updated and same thing no reviews.. there 2 new.
Really only need during flowering and even then probably the last 2 weeks anyway
You will not lose CBD. CBG turns into THCa or CBDa and primarily genetics will be deciding how much cannabinoid percentage results in a particular strain although some outside influences can better or worse the condition. CBD is also formed much earlier than THC they have found in studies of CBD is present even in vegetative growth. So UV light should not have the effect of diminishing CBD for the increase of THC. UV light should result in a increase in both cannabinoids. If any at all. Also they used same plants.. So was it a cut or by seed if by seed then no control. We know a lot more about cannabis now then in 1988 I'm also finding the THC percentage hard to believe way back then when we barely have 32 percenters now.
sorry if i don't get anything information at this video, because my English is bad
So i have some questions :
- Do plants need uv lamps, and how much is enough (for CFL bulbs, I have a black light uv a 40w)
- Should use in what period?
- Can be used from beginning to end of a tree's life cycle?
Please help !!!
Addedeighy foot flurs years🥳ago light rails next to 600hps to bcreased trikes more potent too BadMF
Right lol not a hypothesis it works but have eye protection! BadMF
im trying to fing the source where it states that thc with less cbd is unhealthy. So would that make THC isolates super toxic?
Any chance you will be reviewing a Green Sunshine Company light ?
Contact them and tell them to send a light to Shane. If they won't send one, wonder why....
I'm waiting for them to send me the new model. Coming soon I'm told
@@MIGROLIGHT Surely the Electric Sky 300 will be up there on the charts ? Would be great to compare to Migro 200 as I think they both do a 2x4 ?
Shane, I think you should do a Migro 200 Veg, which would be a bit cheaper than buying two Migro 100 veg. ;)
I just bought the Marsh hydro UV and IR bars I can't wait to see if there is a difference in my plants ✌
Are you saying that the sun does not output UVC?
Some good info..and thanks for being brave enuff to do this... one thing tho you cant sacrifice cbd for thc...thats already predetermined by the genetics..you can only max out the plant to wat ever its genetics allowe be that its maximum thc and cbd..but you cant lower cbd if you up thc..you can alter the outcome of the ratios but ther will always be a maximum amount preprogramed already in the plant...but if I had perfectly replicated the environment to get near enuff the best I could out of a plant and for example I got a ratio of 15% thc and 5% cbd by me further bettering that environment to its peak and upping the uv light content, yes I might be able to max out my thc to the predetermined genetic peak , which in this example was say 20%..so we would get a plant that was now producing 20%thc but the cbd would not lower and would still remain at its predetermined max wich in our example was 5% and it would stay at 5%. I hope you was able to understand wat im saying..I just wanted you to be able to give the best info..as you aways do...thanks
I use 2 ts 1000 along with a wish square blue red light in between in my 4x4. I've noticed benefits from adding the blurple like for 15 at startup of light cycle and 45 at the end. while in flowering, in 12 n 12. I'm running ethos photos, but I wondering the same lighting for autos how they would do.
Check his videos out think u will like
GREAT CONTENT !! THANKS!!!
One would assume that with cannabis being legalized in growing numbers of states that more concrete evidence and research would come out in regards to what does and does not work. Instead it has just increased hype and rumor, and recited marketing claims (look at all the nutrients out there!!) I grow more than cannabis, and I love seeing well documented tests as it can be applied to all plants. Can't wait to see what you come up with.
1.5x video speed 😣
I want to know if UV effects the Bud to Leaf Ratio. My indoor does Not have UV and its a Nice cola with few leaf. Outside the same Pheno has ton of leaf. I think its from the UV, Anybody know about this?
In combo with Advanced Nutrients bud factor x it would give bigger difference cause of the uvb
Hey I’d like to see you do a test on Metal Halide 6000 k bulb like a supernova bulb ! You never see people use metal halides because of the myth that they don’t do well ! I have better luck with metal halide super nova bulbs and you could test a metal halide 3000 k bulb I use with the super nova and I’ll put against anything or any light bulb on market! The brand of bulb in 3000 k is called Agro Sun! Because I don’t like using anything else but super nova bulbs! That would be a test worth doing!
Never thought you would talk about cannabis lol thought ur more conservative.
Another amazing video, thank you!
thinking of ordering one of ur uvb light but where is it being shipped from because i worry about it getting broke in shipping ????
Only weed needs UV or all vegitables like salats, microgreens etc...?
Yes or no?
Nice review
Non uvb 25%thc uvb plant 32%thc u say increase of 28% where? 👍math make no sense?🤣
If you start at 25% and increase by 28% that does not mean 25 + 28. That means 25% + (.25*.28).
His math is correct 🤓
I did it once, LED's with UV. The results almost sent people to the hospital... No joke.
How’s that?
What do yoh mean?
I had the same experience with 10.0 reptile bulbs (added like 60w Mer m2 at 1.5 feet) growing og#18 under blurple leds. I had already grown og18 under hps and under blurple leds without uvb supplement. I push the og18 to 84 days flower for best smell and complex effect. Basically with the uvb supplement a bong hit of 0.12g would affect me intensely for 6 hours, VS standard bong hits of 0.2g of other strains would affect me intensely for 10-90 minutes... Also 1 friend got a psychosis from a bong hit and most friends (daily stoner!) thought they needed to go to hospital. I measured a consistent increase in my bpm from approx 60 to 110 for 5-20 minutes after a bong hit. I know it's very subjective but in my experience the difference in complexity/depth of taste and effect was incredible. 0.5g would last me a day, compared to anything else where I would make 5g disappear in a day... Also: with uvb the og18 effect seemed to have no ceiling (I had some fun and wierd experiences trying to find that ceiling - an I'm the type that takes a fat dab before/for breakfast). After spending 10 years trying to find bud with a comparable taste/effect I gave up as nothing comes close... So I started a garden again and just got the migro310 this week! Will report back in 2-3 months if it made my current day 35f Bubba kush 'express itself'/'release its poison' :) BTW my og18 grown under uvb I could smell 1g from 100meters no joke. My current non-uvb flowers I need to stick my nose in the bag to get some smell LOL (yes I harvest late and dry slow and cure to 62% etc)
So basically my last uvb supplemented grow literally sent my best bro to psychiatric prison for nearly a year (he was very stable and healthy and a very sober smart student doing plenty of sport aswell before that psychosis inducing bong hit), it made me experience 'hearing my thoughts echo through my head like it was someone else speaking'... WTF??? An I used to grow shrooms so I'm not someone to exaggerate effects: usually store bought weed to me is very mild and just calms/slows me down a bit and strains lack personality. Try uvb supplement and stay safe...
@@airsoftsniper9191 🤥🤥🤥🤥🤥🤥
Noticed difference with light had uvb that plants under ha d ore trichs and lots of trichs on the sugar leaves and a light without uv but with far red high efficiency light that the trichs production was lower
What would I benefit more from a strip light or bulb if so how many light bulbs we looking for a 4X4 TENT
