Mate this video is a master class on uv lighting. I bought some of your 310 uv lights and man they make a difference. A commercial strawberry grower I know told me some time ago that uv supplementation was his secret formula to his super tasty berries🍓
Thank you migrow. You make it a lot easier to understand the so often very confusing world of lights and how they work. I too was sceptical about uvb increases, now I'm a little more clued up thanks!👍
I would go through and re-test the animal bulbs but using the Reptisun 5.0 t8, Reptisun 10.0 t8, Arcadia 12% t8 and Arcadia 14% t8 bulbs. They generally run cheaper than the ones you mentioned here and in my personal experience are much more efficient, even over larger areas.
Pretty sure quartz glass passes all or most of the UVB and UVC. Source I use to keep fish and all the UVC bactericidal lights all had quartz glass sleeves between the bulb and the water, you needed to order specialist quartz sleeves as normal glass tubes resulted in bacti/algal blooms in the tanks (high load systems).
Hey bud Old vid but based on it, I purchased the Agromax pure UV.. and 2- 54 watt single fixtures After 6 months, I believe it helps. And definitely worth it.. Thanks man
Thanks again Shane. I tried one reptile bulb as proof of concept recently and am looking to add a 2' fixture to each of my areas and wanted to get it right, from the get go.
I owned and operated a chain of tanning salons with powerful tanning beds putting out both UVA and UVB. Yes you should wear eye protection, but these light don't have enough output to burn you nearly as much as a 20 minute tanning bed with 24-36 6ft GLASS bulbs, although the jury seems to be out on how much improvement they offer to a grow.
I was told 15 minutes at a time, for a total of up to 2 hours. Using this during the last 2 to 3 weeks of flower this next grow. Will see and report back results.
UVA also has a place in the signal you send your plants, not just for quantum purposes but also for the sake of proper phase coherence of your signals' wavefront profile. I'm speaking about light as if it's a form of radio because it is.
I bought some Agromax pure UVA 25% - UVB 75% 45 watts t5, and the Agromax plus UVA 45watt t5, and the 10,000k finisher bulbs there the best, I immediately noticed the difference like night and day, I've been growing the same Runtz strain for over a year now and when I added the UV spectrum they noticeably got more potent more trich's, I run them for an hour a day( right at the halfway mark of my lighting schedule simulating High Noon 12:00), then constantly/12hours with my LED's at the end of flower ( I even hit my plants in flowering with UVC to kill all mold spores, it really works, I run 40-60% humidity in flower the resin damn-near be running down the stems from the buds) I run the UVC 3mins a day twice a day sun up and sun down (in flower 3 times a day one extra time mid day/high noon/in the middle of the light schedule) ...... ✌❤
@@ronevergrow8319 Yep I use UVC and Ozone to keep WPM under control. Bought a cheap UVC bulb and hand wand the plants, works great to kill mildew. just getting started with UVB though this week though. Looking forward to monitoring results
Hi Mark. Great info + well presented as always. A small point I want to raise: I was lead to believe (via the adjust-a-wings website) that it is actually bare aluminium that absorbs UV photons and that a special white-coated aluminium is best for reflecting UV. This is why they (AAW) supply white “wings” with their CMH fixtures. Thoughts? Cheers mate!
Would love to see an Ushio G15T8E 14.7W Midrange UV Fluorescent Lamp tested. Its designed to output at 306NM, and no UVA. Its pricey at $30, but we'd eliminate the UVA.
@@MIGROLIGHT hello, is my first grow with uvb and with white reflectors (metal white paint), 1rst week 15min on 45 min off (6 times on ) , 2nd week and running, 30 min on 30 min off (7 times on)... with hlg led lights, a couple of plants are 30 cm from de bulb and they seem good, but a couple of small week plants show light burn
i think you should add a little red or blue led on the top to show the light is on as like you said you cant really tell its on i got my uvb set to come on 5.hrs after light comes on for 1hr-2hr
Please test the Arcadia 14% UVB T5 HO bulbs. Btw thanks for that tid bit about what reflects UVB. I think the refelctors I have are plastic coated, time to break out the foil 😂.
I second this! Also, there's some discussion that the Agromax PureUV seem to burn plants. Is there UVc radiation being put out? Some seem to claim that there could be wavelengths down around 270nm being given off. Anyway to test for UVc?
I wonder if the uvb causing resin production simply causes cannabalization like during flushing or actually is bleaching the flower... either way both can be fixed but the cannabalizism is good in my eyes cause I only add uvb during flush after using the eye hortilux blue mh->ceramic hps both 600w (Ive been tinkering with a sativa blend indoor so I need blue during veg to help with height after trying other wise hps them all the way through for massive ladies..). I wonder if they just needa move it back some or simply remove its reflector/lower its efficiency (remove some reflective/coat some surface..)
@@prestontingley8914 UVB or any UV to my knowledge doesn't cause cannibalization directly ime. And if you're getting bleached tops or burnt leaves its simply too much light, UV, even too much heat. My UV lamps stay on with my reg lights bout 24" to 18" from canopy and all my leaves point up right at my UV lights. I turn them on when I flip the lights to 12/12, some people like to use it in veg too but I haven't seen much benefit doing so. I use T5 ho 14% UVB Acadia bulbs as said in my original comment. Change them every 6 months of useage for best results, the UV output drops as bulbs get used. Back to your question one could assume the increase in THC from UVB exposure might make the plant need/use more nutes. Although one wouldn't think it would be much of a metabolic increase considering the THC increase is only around 25% by ratio. But this could lead said plants to cannibalizing but not bleaching given the rare situation but I'd doubt it as much of a factor tbh. That's my best theory for you friend, a majority of growing knowledge isn't proven its anecdotal for the most part. So take it with a grain of salt but I pride my myself on correctness so I'm not the guy spreading total bs bro science hurting the community instead of helping it. I'd recommend you learn to build some LED lights with HLG boards. It's easy man and super worth while. It'll help alot with heat overall which is probably your issue from what it sounds like. But if you're dead set on HIDs the 315 CMH\LECs with bulbs in 3100k are perfect for full cycle vs the ceramic HPS which has a poor spectrum in comparison. Also you can use them for full cycle no need to change lights or bulb from veg to flower. Also the 315w versions have the most options and its not a total death ray in the center of the light footprint like with more powerful lights which I think is most likely your issue. The 630w CMHs with 2 315w bulbs are the best of the HIDs even over the DE versions they bring more to the table. But if I was you I'd finish my crop if I had one going then sell that light and learn to build a LED light. Specifically HLG best price, high efficiency/low heat output, best tech, best spectrum. Happy growing man.
What great information! I have 2 Agromax pure uv bulbs in my 4'x4' tent & currently run them for 15 minutes X 4 times a day, last two weeks of flower, 24" above canopy! Is that too much? Thanks
A B I’m of the opinion the FS + UV bulb by hortilux is wonderful for filling out the spectrum that you are losing from the glass blocking spectrum from air cooled hoods, and for getting w/e is lacking from your led spectrum. If you want actual UV supplementation, the AgroMax bulb is better. I would like to hear Migro’s opinion on this as well.
APPARENTLY SHANE SEEMS VERY AGAINST THIS! IT LOOKS TO HAVE A GOOD AMOUNT OF UVB, AS WELL AS UVA, AND SHANE'S GOT THE METERS, AND I'VE GRAPPLED WITH THIS QUESTION SEVERAL TIMES HERE. NO RESPONSE. THEN SHANE STARTED SELLING "CMH" KITS, AND I BEGGED FOR A REVIEW THEN, ESPECIALLY! MAYBE THEY'RE PERFECT FOR UVB? MUCH MORE WATTAGE! MAYBE NOT? WHEN PERTINENT INFORMATION IS MISSING, THERE'S SOMETHING "THEY" DON'T WANT YOU TO KNOW! HOWEVER, SHANE IS ALWAYS STRAIGHT UP HONEST! AND PRESENTS THESE LIGHT FIXTURES MORE ACCURATELY, AND HONESTLY THEN ANYONE I'VE HEARD! WHAT SHANE SAYS, I KNOW IS ACCURATE! WITH THE GREAT EQUIPMENT HE HAS, ESPECIALLY HIS MIND, HE'S MORE THAN PROVEN THIS! STILL VERY STRANGE THOUGH? HE DID SAY HE TESTED HID LIGHTING, BUT I BELIEVE THAT WAS ONLY HPS/MH, NO CMH, DEFINITELY NOT THE 10,000K! I'LL SEND HIM A NEW ONE TO TEST, IF HE'S INTERESTED. I HAVE 3-4 NEW ONE'S! PLENTY OF UVA, THEN THE GRAPH STOPS AT UVB, GETTING LOWER, BUT STILL AROUND A .4-.5 IN INTENSITY WHEN THE GRAPH STOPS. MAYBE LOWER AMOUNTS OF UVB, BUT 315W, NOT 30W? IF ANYONE KNOWS ANYONE WHO HAS TESTED THESE, AND SHOWS THE UVB RANGE, PLEASE, LET ME KNOW BOUGHT A FEW 315W 10,000K LAMPS ON SALE. ONE CRACKED IN SHIPMENT, AND THEY SENT 2 MORE. SO I HAVE A FEW NEW ONE's, IF NEEDED TO TEST?👍💜🙏
Thank you for the comparison, it's good to see more testing being done on UVA and UVB. I want to know the interaction between them but that would mean actually grows with the different bulbs. I'd like to see the California SolarSystems UVB added to the comparison. Also the Flower Power should be run with higher wattage, say least an F32T8 ballast all the way up to their max (70w I believe?). And you can't forget to throw your new UV light in the mix. 😊
I'm growing some chilli and tomato plants indoors to pot them out when the weather warms up (which should be happening from this week in London). We supposed to start hardening off the plants before planting out. When I've done this, the plants are suffering from sun scolding/burning as maybe the plants are not used to the UV rays? Would using UV indoors at intivals help bulk up the leaves to make them stronger and withstand the suns rays and hopefully lessen the time of hardening off the plants (as long as temps are right)? Would this be something useful to trial out?
Could you have put the 4ft in your home made reflector or a 4ft reflector to get the 3X or is the coating they used blocking it from coming out back of bulb ? Why make it frosted anyways cheapest I'm sure
Thank you so much for doing to video on UV light. This came at the perfect time for me because I was seriously thinking about purchasing a quantum board with UV LED lights. The problem I’m having right now Is my basil is not turning green even after several weeks under my full spectrum 3500k lm301b (with 660 far red) bar lights. I was thinking I possibly need some UV supplementation for basil as other Microgreens so quite well with my lights. I’m now thinking is supplementing with the Agromax!
Hey Shane, Seti/Seoul-Viosys has developed a 280-290nm UVB LED exactly for this purposes and they claim to produce around 10mW at 6v/150mA. You can get them from digikey and their part.-no. is TUD8MF1B, description: CUD8GF1B on starboard. They cost around 20€ each. 10mW does not sound like much but according to the data sheet it's quite enough. The only thing missing is some UVA but that's not a problem with LED's. A few 365nm diodes should provide enough UVA to make it a "healthy UVA/B combination".
Hi, our 20W UVB Fluorescent delivers 110µw/cm2 UVB over a 1.5m x 1.5m space (2.25m2). This is a total UVB of 110 x 2.25 x 10,000 (1m2 in cm2) = 2,475,000 µw or 2,475 mw of UVB. You would need 245 x 10mw LEDs to do the same job. They are nowhere near as effective as Fluorescent I'm afraid. Link to MIGRO UVB here: www.migrolight.com/product/migro-uvb-310/
@@MIGROLIGHT Thanks, bro. I know about the output difference but using 285nm exactly is 10x more efficient triggering the UVR8 receptor and so you need 10x less. All other UVB wavelength (290+nm) could be wasted energy when using 285nm. Please search for "the next evolution in horticulture lighting" by Dr. P. Barber SETi
hey could you use your sprectralradiometer to check out if grow room glasses are blocking harmful light. I just got method 7 agent 939 and I feel I still see alot of heavy blue light.
too bad agromax are only available through HTG and if you aint in USA they dont ship outside of the US so your light is the best UVB available to the world market and just take my money. If we could just get a little lower prices on that shipping that would be great but I aint complaining! Thank you for all your research and pushing technology and availability forward using scientific methods, bravo you have my full support and will be grabbing some 310s AU bound
i easily buy agromax (i from eastern EU) We have service for the purchase anything from the usa. They buy what you need in the US - brought to their own warehouse and send it to you.
It would help if you knew more about your subject. Let's start with that the photoreceptor for UVB is UVR8. UVR8's peak sensitivity is at 285-288 nm. High frequency UVB (< 300 nm) has, per Zhang and Bjorn, TEN TIMES the photoactivity that low frequency UVB (> 300 nm). So just stating that a particular lamp emits four times as many UVB "photons" without being specific as to the wavelengths being emitted, is not a sufficient comparison to base a lighting purchase on.
Wow this opens a lot of questions. I was given a 1000 w old quartz light that I had repaired. I am now wondering if that light will produce the desired uvb. In a test run that light did give me sun burn in my ne ck on a winters night in my greenhouse section.
So if I just have UVA then I would need to extend the time period the light is on? I think I heardUVB is 10/100 more potent than UVA so if it’s 10 times I could just leave it on for a day then off for a day? But if it’s 100 times I would need to increase the intensity along with the amount of time per light cycle. Note: I have multiple UVA lamps so intensity wouldn’t be an issue.
Newer lights such as Lec Cmh and Smd Leds have more uv than the older lights you really dont need to add any if your using these lights they have enough to harm you without protection . Uv also keeps the bugs from biting your tomatoes .
Tony Lemon it also helps to prevent mildew, and reduce the time needed for hardening off of tomatoes and pepper plants when you take full size plants outside in April. Isn’t it fun to have full size plants when your neighbors are just buying seedlings?
It is important to note, which it was not in this video, that the receptor for UVB, which is called UVR8, has its peak sensitivity at 285 -288 nanometers (nm) of wavelength. Bioactive of the type we're trying to promote is TEN TIMES greater at 285 than it is at 300 nm. So just saying something has 4 times as much UVB, without mentioning the specific frequencies, and the difference in bioactivity reflects either incomplete research into the subject or deliberate deception. I prefer to believe it's the former.
@@engell3707 the black lights block out all of the spectrum except the UV and regular fluorescent bulbs dont have the much UV in them to begin with then it is safe to assume they are not great at producing UV, because they are just allowing what UV that IS present in the spectrum through and blocking everything else - is pretty much what he was saying
Is the Philips broadband bulb the only other choice? Is there another comparable bulb to the Agromax pure uv? Here in the in the US they are completely sold out. (I would suspect you had something to do with that, lol) The only Agromax pure uv bulbs I can find are from Africa at 3 X the cost. Thanks in advance for any info you can give me.
If i remember correct you mentioned a 6h cycle during the flower stage in another video. And in this video you said a couple of hours on and off. Would you mind explaining why a few hours on/off is enough?
D4rk BliZz4rd UV is strongest when sun is closest to earth. As the earth rotates the UV strength increases and decreases in direct proportion, sun typically is closest to earth at noon. See Perihelion and Aphelion, those calendar dates when sun is closest and furthest from earth. At more acute angles the UV is scattered by the atmosphere.
Also he mentions that the bulb puts out much more UV than natural sunlight. I believe that he meant to run the uv no more than an hour, and to do that no more than twice a light cycle.
What about this, im growing plants indoor for my outdoor garden like peppers tomato etc if i use (also) uv light to grow my plants (when it is to cold outside). Wil it be better for the plants when i put the plants outdoors in sunlight?
And everyone with you. There is a study but it's from the 80s. Even back then the effect was shown to be of different strength between different strains. Now whe have many plants that have evolved under hps with no uv-b so many new strains may have been selected to have near max potency without uv-b. As long as you only get normal reptile flourescents you can just try it out quite cheaply - only need 6h per day only for later flowering (?last 14 days?)
Deff more info please. Maybe we can get a pack of purple sharpies of different purples an just cover the led chip emitter with it?Use those 2 dollar alliexpress 50w chips an get 500 dollar 50 watt UVA UVB range led chips for like cents ? I'm trying to find how to make UV an UVB stuff or lights at home and there is no info on it.
Does uvb kill microbial life on plant surfaces? If not is a uvc bulb from agromax to powerful for our medicinal plant? With the 2' agromax uvb bulb, will any 2' florescent light fixture work with this bulb?
I have 2 of the agro Max uvb Flouresen t5 23 inch. How long are people leaving these on? I didn't do full cycle.. Just doing 5 or 10 min of use. What time schedule so these need to be on?
Thank you. Can you recommend a supplier for the Agromax PURE UV (12% UVB output) bulb? as they seem to be unavailable whenever I look. Also could you test the Arcadia T5 Dragon Lamp 14% UVB - 24w as they seem to be readily available.
@@MIGROLIGHT Thanks for your reply. Unfortunately when I try UBUY it doesn't include UVB bulbs, I've tried lots of different search terms but no luck.

It may be better to use Arcadia D3+ Reptile Lamp T5 12% UVB which I can get delivered for £47.07 and can be set at the same height as your MIGRO lights and should cover a 2' X 2' square nicely at that height without damaging the plants.

I have been using 10k metal halides aka H.I.D for supplemental uva and uvb spectra for over 10 years. I tried the uv t5 ho crap and it doesn't work the amount of uvb emitted is too low. In a 10k 1000w metal halide about 30% of the spectral energy is within the UV spectra. But remember not every 10k metal halide is made equal some will emit very low amounts of uvb and high amounts of uva while others will emit more uvb and maybe even some UVC.
NEED HELP, been trying to find the agromax pure uv light and it is not available anywhere at all anyone know where might have them in case i over looked something 2 or 4 foot is fine\
The question with the Agromax is does it produce the desired 1w per m² over the 3m² area? Or is it more like 3w per m² so over providing for a small area?
@@dreamweaverskennel2952 it's what I have gone with and am very happy with results. If your UK base Progrow.co.uk in Exeter do a set of 2 1 meter ones for about £155 and a set of two 1.2 meter bulbs for about £175 if your interested. 1 meter for 1.2x1.2m 1.2 bulbs for 1.5mx1.5m Would be interested in a side by side but unfortunately Shane can't do that so will have to look to others for those kind of side by sides.
Would it be advisable to hang these T5 agro bulbs vertically around the plants to give exposure to the bottom of the plant as well? Or best to let the light land on the leaves from above? If hung vertically around the plant it would side-light the vertical buds and kind of skip past the horizontal leaves, right? I assume you want the UV on the resin-producing buds and not so much the leaves?
He tells you in the first couple mins of the video. 1 led that is 0.2watts was 50€ and dosent do anything. That UV board would cost $100,000.00 to do anything.
great video but you are wrong when you say H.I.D does not emit any real uvb, i use 10k metal halide vertical bare bulbs designed with low iron glass from solis-tek for uvb / uvc output, i spoke with the manufacturer these bulbs emit 30% of they're total spectral energy within the UV spectra and they emit uva, uvb and uvc. also they're bulbs are made with low iron glass so that the UV spectra can pass through the glass.

Can you please do a vid on California Light Works UV product vs PureUV? @migro
I know it's been a while but California light works recommends the Agromax pure UV as a replacement bulb so I have read.
You do realize that the shorter the wavelength the greater the energy. UVB at 285 nm is about 10 times more energetic than 315nm.
Shhhhh. People dont like facts. They'd rather waste money on the newest trend. Lol
Great comment. The tighter the wavelength, the further it carries without falling apart.
It's a Bell curve. Joules go up exponentially as the frequency increases. 1 photon @ 285nm has more energy than 1000 photos at 315nm.
In laments terms please gentlemen. 😊
Would you please clarify- On/off for an hour.. “on” for every other hour for the entire day light cycle?
What i understood ..is .. 2-3 hours totally ( 1 hour each time ) ..during daylight cycle... 🥴
I was told 15 minutes at a time, for a total of up to 2 hours. Using this during the last 2 to 3 weeks of flower this next grow. Will see and report back results.
Hows your results till today? Just curious.

UVA also has a place in the signal you send your plants, not just for quantum purposes but also for the sake of proper phase coherence of your signals' wavefront profile. I'm speaking about light as if it's a form of radio because it is.

The SolarSystem UVB by California Lightworks is a 24w T5 with reflector. A little expensive, but very nice. With 5-year warranty.
Hi Mark. Great info + well presented as always.
A small point I want to raise: I was lead to believe (via the adjust-a-wings website) that it is actually bare aluminium that absorbs UV photons and that a special white-coated aluminium is best for reflecting UV. This is why they (AAW) supply white “wings” with their CMH fixtures.
Thoughts?

@@MIGROLIGHT hello, is my first grow with uvb and with white reflectors (metal white paint), 1rst week 15min on 45 min off (6 times on ) , 2nd week and running, 30 min on 30 min off (7 times on)... with hlg led lights, a couple of plants are 30 cm from de bulb and they seem good, but a couple of small week plants show light burn
I use em too.
Just brilliant as always. Sincere thanks.👍
i think you should add a little red or blue led on the top to show the light is on as like you said you cant really tell its on i got my uvb set to come on 5.hrs after light comes on for 1hr-2hr
This man is the Bill Gates of growing plants, may the 420 be strong with you my friend 👌🏼
Please test the Arcadia 14% UVB T5 HO bulbs. Btw thanks for that tid bit about what reflects UVB. I think the refelctors I have are plastic coated, time to break out the foil 😂.
I second this! Also, there's some discussion that the Agromax PureUV seem to burn plants. Is there UVc radiation being put out? Some seem to claim that there could be wavelengths down around 270nm being given off. Anyway to test for UVc?
I wonder if the uvb causing resin production simply causes cannabalization like during flushing or actually is bleaching the flower... either way both can be fixed but the cannabalizism is good in my eyes cause I only add uvb during flush after using the eye hortilux blue mh->ceramic hps both 600w (Ive been tinkering with a sativa blend indoor so I need blue during veg to help with height after trying other wise hps them all the way through for massive ladies..). I wonder if they just needa move it back some or simply remove its reflector/lower its efficiency (remove some reflective/coat some surface..)
@@prestontingley8914 UVB or any UV to my knowledge doesn't cause cannibalization directly ime. And if you're getting bleached tops or burnt leaves its simply too much light, UV, even too much heat. My UV lamps stay on with my reg lights bout 24" to 18" from canopy and all my leaves point up right at my UV lights. I turn them on when I flip the lights to 12/12, some people like to use it in veg too but I haven't seen much benefit doing so. I use T5 ho 14% UVB Acadia bulbs as said in my original comment. Change them every 6 months of useage for best results, the UV output drops as bulbs get used. Back to your question one could assume the increase in THC from UVB exposure might make the plant need/use more nutes. Although one wouldn't think it would be much of a metabolic increase considering the THC increase is only around 25% by ratio. But this could lead said plants to cannibalizing but not bleaching given the rare situation but I'd doubt it as much of a factor tbh. That's my best theory for you friend, a majority of growing knowledge isn't proven its anecdotal for the most part. So take it with a grain of salt but I pride my myself on correctness so I'm not the guy spreading total bs bro science hurting the community instead of helping it. I'd recommend you learn to build some LED lights with HLG boards. It's easy man and super worth while. It'll help alot with heat overall which is probably your issue from what it sounds like. But if you're dead set on HIDs the 315 CMH\LECs with bulbs in 3100k are perfect for full cycle vs the ceramic HPS which has a poor spectrum in comparison. Also you can use them for full cycle no need to change lights or bulb from veg to flower. Also the 315w versions have the most options and its not a total death ray in the center of the light footprint like with more powerful lights which I think is most likely your issue. The 630w CMHs with 2 315w bulbs are the best of the HIDs even over the DE versions they bring more to the table. But if I was you I'd finish my crop if I had one going then sell that light and learn to build a LED light. Specifically HLG best price, high efficiency/low heat output, best tech, best spectrum. Happy growing man.
Love this channel!! Thank you, Shane for this possible To is consumers :)
Will you be taking a look at HLGs new UVA bar? It isn’t officially for sale for another 2 weeks but it’s on their site.
Shane, can you tell us what wattage you were running the SolaCure Flower Power lamp at?
Pardon me if this question sounds a bit silly but will two four-foot agromax bulbs the overkill for a 5 x 5 tent?
What great information! I have 2 Agromax pure uv bulbs in my 4'x4' tent & currently run them for 15 minutes X 4 times a day, last two weeks of flower, 24" above canopy! Is that too much?
Thanks
In a California lightworks video, the guy says you could runb it for 6 hours straight
Have you tried the hortilux power veg t5 its supposed to be a uv bulb
A B I’m of the opinion the FS + UV bulb by hortilux is wonderful for filling out the spectrum that you are losing from the glass blocking spectrum from air cooled hoods, and for getting w/e is lacking from your led spectrum. If you want actual UV supplementation, the AgroMax bulb is better. I would like to hear Migro’s opinion on this as well.
Have you done any tests, UVA vs UVB ?
I wanna see a test from the 10'000k CMH bulb 😉
600w 10k Phillips MH could be informative
Or the eye hortilux 600w ceramic hps...😈⛽️
APPARENTLY SHANE SEEMS VERY AGAINST THIS! IT LOOKS TO HAVE A GOOD AMOUNT OF UVB, AS WELL AS UVA, AND SHANE'S GOT THE METERS, AND I'VE GRAPPLED WITH THIS QUESTION SEVERAL TIMES HERE.
NO RESPONSE. THEN SHANE STARTED SELLING "CMH" KITS, AND I BEGGED FOR A REVIEW THEN, ESPECIALLY!
MAYBE THEY'RE PERFECT FOR UVB? MUCH MORE WATTAGE!
MAYBE NOT?
WHEN PERTINENT INFORMATION IS MISSING, THERE'S SOMETHING "THEY" DON'T WANT YOU TO KNOW!
HOWEVER, SHANE IS ALWAYS STRAIGHT UP HONEST! AND PRESENTS THESE LIGHT FIXTURES MORE ACCURATELY, AND HONESTLY THEN ANYONE I'VE HEARD!
WHAT SHANE SAYS, I KNOW IS ACCURATE! WITH THE GREAT EQUIPMENT HE HAS, ESPECIALLY HIS MIND, HE'S MORE THAN PROVEN THIS!
STILL VERY STRANGE THOUGH? HE DID SAY HE TESTED HID LIGHTING, BUT I BELIEVE THAT WAS ONLY HPS/MH, NO CMH, DEFINITELY NOT THE 10,000K!
I'LL SEND HIM A NEW ONE TO TEST, IF HE'S INTERESTED. I HAVE 3-4 NEW ONE'S!
PLENTY OF UVA, THEN THE GRAPH STOPS AT UVB, GETTING LOWER, BUT STILL AROUND A .4-.5 IN INTENSITY WHEN THE GRAPH STOPS. MAYBE LOWER AMOUNTS OF UVB, BUT 315W, NOT 30W? IF ANYONE KNOWS ANYONE WHO HAS TESTED THESE, AND SHOWS THE UVB RANGE, PLEASE, LET ME KNOW
BOUGHT A FEW 315W 10,000K LAMPS ON SALE. ONE CRACKED IN SHIPMENT, AND THEY SENT 2 MORE. SO I HAVE A FEW NEW ONE's, IF NEEDED TO TEST?👍💜🙏
very good as usual. still educating folks
Thank you for the comparison, it's good to see more testing being done on UVA and UVB. I want to know the interaction between them but that would mean actually grows with the different bulbs.
I'd like to see the California SolarSystems UVB added to the comparison. Also the Flower Power should be run with higher wattage, say least an F32T8 ballast all the way up to their max (70w I believe?).
And you can't forget to throw your new UV light in the mix. 😊
What about using mirror for a reflector
hello thanks for the content! Does the agromax lamp need a ballast?
The beep dosent measure resistance it checks continuity
I'm growing some chilli and tomato plants indoors to pot them out when the weather warms up (which should be happening from this week in London).
We supposed to start hardening off the plants before planting out. When I've done this, the plants are suffering from sun scolding/burning as maybe the plants are not used to the UV rays?
Would using UV indoors at intivals help bulk up the leaves to make them stronger and withstand the suns rays and hopefully lessen the time of hardening off the plants (as long as temps are right)?
Would this be something useful to trial out?
Could you have put the 4ft in your home made reflector or a 4ft reflector to get the 3X or is the coating they used blocking it from coming out back of bulb ? Why make it frosted anyways cheapest I'm sure
What is the distance from the canopy you use to get these results?
My Hydroponic Grow Towers are made of FDA-compliant ABS plastic, Will 385-395nm UV-A Damage this plastic? Severely?
Thank you so much for doing to video on UV light. This came at the perfect time for me because I was seriously thinking about purchasing a quantum board with UV LED lights. The problem I’m having right now
Is my basil is not turning green even after several weeks under my full spectrum 3500k lm301b (with 660 far red) bar lights. I was thinking I possibly need some UV supplementation for basil as other Microgreens so quite well with my lights. I’m now thinking is supplementing with the Agromax!
@Andrew Brent She probably means it is too light green- as in not enough nitrogen in the pots(?)
So a black light florescent tube would give the best results?
Hey Shane, Seti/Seoul-Viosys has developed a 280-290nm UVB LED exactly for this purposes and they claim to produce around 10mW at 6v/150mA. You can get them from digikey and their part.-no. is TUD8MF1B, description: CUD8GF1B on starboard. They cost around 20€ each. 10mW does not sound like much but according to the data sheet it's quite enough. The only thing missing is some UVA but that's not a problem with LED's. A few 365nm diodes should provide enough UVA to make it a "healthy UVA/B combination".
Hi, our 20W UVB Fluorescent delivers 110µw/cm2 UVB over a 1.5m x 1.5m space (2.25m2). This is a total UVB of 110 x 2.25 x 10,000 (1m2 in cm2) = 2,475,000 µw or 2,475 mw of UVB. You would need 245 x 10mw LEDs to do the same job. They are nowhere near as effective as Fluorescent I'm afraid. Link to MIGRO UVB here: www.migrolight.com/product/migro-uvb-310/
@@MIGROLIGHT Thanks, bro. I know about the output difference but using 285nm exactly is 10x more efficient triggering the UVR8 receptor and so you need 10x less. All other UVB wavelength (290+nm) could be wasted energy when using 285nm. Please search for "the next evolution in horticulture lighting" by Dr. P. Barber SETi
hey could you use your sprectralradiometer to check out if grow room glasses are blocking harmful light. I just got method 7 agent 939 and I feel I still see alot of heavy blue light.
too bad agromax are only available through HTG and if you aint in USA they dont ship outside of the US so your light is the best UVB available to the world market and just take my money. If we could just get a little lower prices on that shipping that would be great but I aint complaining! Thank you for all your research and pushing technology and availability forward using scientific methods, bravo you have my full support and will be grabbing some 310s AU bound
i easily buy agromax (i from eastern EU)
We have service for the purchase anything from the usa. They buy what you need in the US - brought to their own warehouse and send it to you.
It would help if you knew more about your subject. Let's start with that the photoreceptor for UVB is UVR8. UVR8's peak sensitivity is at 285-288 nm. High frequency UVB (< 300 nm) has, per Zhang and Bjorn, TEN TIMES the photoactivity that low frequency UVB (> 300 nm). So just stating that a particular lamp emits four times as many UVB "photons" without being specific as to the wavelengths being emitted, is not a sufficient comparison to base a lighting purchase on.
Curious why you didn't test the hortilux uv t5 lights?
Wow surprised by the internal reflector on the solacure, will look at making external reflector.
Wow this opens a lot of questions. I was given a 1000 w old quartz light that I had repaired. I am now wondering if that light will produce the desired uvb. In a test run that light did give me sun burn in my ne ck on a winters night in my greenhouse section.
So if I just have UVA then I would need to extend the time period the light is on? I think I heardUVB is 10/100 more potent than UVA so if it’s 10 times I could just leave it on for a day then off for a day? But if it’s 100 times I would need to increase the intensity along with the amount of time per light cycle. Note: I have multiple UVA lamps so intensity wouldn’t be an issue.
Newer lights such as Lec Cmh and Smd Leds have more uv than the older lights you really dont need to add any if your using these lights they have enough to harm you without protection . Uv also keeps the bugs from biting your tomatoes .
Tony Lemon it also helps to prevent mildew, and reduce the time needed for hardening off of tomatoes and pepper plants when you take full size plants outside in April. Isn’t it fun to have full size plants when your neighbors are just buying seedlings?
It is important to note, which it was not in this video, that the receptor for UVB, which is called UVR8, has its peak sensitivity at 285 -288 nanometers (nm) of wavelength. Bioactive of the type we're trying to promote is TEN TIMES greater at 285 than it is at 300 nm. So just saying something has 4 times as much UVB, without mentioning the specific frequencies, and the difference in bioactivity reflects either incomplete research into the subject or deliberate deception. I prefer to believe it's the former.
Are you saying black lights are equivalent....or not as efficient? Hard to understand what you said there.
Also interested in the response.
@@engell3707 the black lights block out all of the spectrum except the UV and regular fluorescent bulbs dont have the much UV in them to begin with then it is safe to assume they are not great at producing UV, because they are just allowing what UV that IS present in the spectrum through and blocking everything else - is pretty much what he was saying
No Phillips 10k Metal Halide Finishing Bulb marketed specifically for this in the salespoint literature?
Sir a CFL 40 Watt consumption would get the job done?
Is the Philips broadband bulb the only other choice? Is there another comparable bulb to the Agromax pure uv? Here in the in the US they are completely sold out. (I would suspect you had something to do with that, lol) The only Agromax pure uv bulbs I can find are from Africa at 3 X the cost. Thanks in advance for any info you can give me.

If i remember correct you mentioned a 6h cycle during the flower stage in another video. And in this video you said a couple of hours on and off. Would you mind explaining why a few hours on/off is enough?
D4rk BliZz4rd UV is strongest when sun is closest to earth. As the earth rotates the UV strength increases and decreases in direct proportion, sun typically is closest to earth at noon. See Perihelion and Aphelion, those calendar dates when sun is closest and furthest from earth. At more acute angles the UV is scattered by the atmosphere.
Also he mentions that the bulb puts out much more UV than natural sunlight. I believe that he meant to run the uv no more than an hour, and to do that no more than twice a light cycle.
Great viddy!!! Good factual info. Thanks 👍
What about this, im growing plants indoor for my outdoor garden like peppers tomato etc if i use (also) uv light to grow my plants (when it is to cold outside). Wil it be better for the plants when i put the plants outdoors in sunlight?
I ask myself how much increase in resin production this adds and if worth the hassle.
And everyone with you. There is a study but it's from the 80s. Even back then the effect was shown to be of different strength between different strains.
Now whe have many plants that have evolved under hps with no uv-b so many new strains may have been selected to have near max potency without uv-b.
As long as you only get normal reptile flourescents you can just try it out quite cheaply - only need 6h per day only for later flowering (?last 14 days?)
He just said for 25$ the agromax one is good for a 9x9. Come w lil fixture too just gotta make a reflector
I think you may have tested potency, before making the vid? Great info, thanks :)
How does one test the potency of their grow. Is the only way is too send it to a reliable lab source?
any links to where we can get hold of these?
Gavin Robson I’ve been looking at the Agromax for awhile now. You can find them at htgsupply.com.
Deff more info please. Maybe we can get a pack of purple sharpies of different purples an just cover the led chip emitter with it?Use those 2 dollar alliexpress 50w chips an get 500 dollar 50 watt UVA UVB range led chips for like cents ? I'm trying to find how to make UV an UVB stuff or lights at home and there is no info on it.
Does uvb kill microbial life on plant surfaces? If not is a uvc bulb from agromax to powerful for our medicinal plant?
With the 2' agromax uvb bulb, will any 2' florescent light fixture work with this bulb?
Rock on Shane.
What would you recommend for 1m²
I have 2 of the agro Max uvb Flouresen t5 23 inch. How long are people leaving these on? I didn't do full cycle.. Just doing 5 or 10 min of use. What time schedule so these need to be on?
Are UV Tubes dimmable?
Power veg t5 s would be a good test
Does weed need to be stronger?
Thank you. Can you recommend a supplier for the Agromax PURE UV (12% UVB output) bulb? as they seem to be unavailable whenever I look. Also could you test the Arcadia T5 Dragon Lamp 14% UVB - 24w as they seem to be readily available.
I bought through a distributor called UBUY. I had to pay a lot of extras but the total was about $90 for two.
If your local garden center carries generic t5 bulbs they can order the AgroMax brand to sell
@@MIGROLIGHT Thanks for your reply. Unfortunately when I try UBUY it doesn't include UVB bulbs, I've tried lots of different search terms but no luck.
I can get 2 X Arcadia T5 Dragon Lamp 14% UVB - 24w delivered for £49.27.
It may be better to use Arcadia D3+ Reptile Lamp T5 12% UVB which I can get delivered for £47.07 and can be set at the same height as your MIGRO lights and should cover a 2' X 2' square nicely at that height without damaging the plants. The 14% UVB may need to be set higher than the MIGRO lights

Could you please test agromax fluorescent UVA- Plus bulb. They are very popular here in Michigan. I seen Growers running this one with people in the room. I just wonder how safe is it. Any information that you can offer on this particular Bulb( the agromax UVA Plus fluorescent T5 4 foot.) Your information could save lives.
Hello my Irish friend, Father O'Malley here. I got a free Panasol II medical light it's 6 foot tall with 4 Philips bulbs and was wondering if this will work. It only let's me set a built in timer for 10 minutes at a time. What do you think. Thanks, Peace
Great info. Thanks again!
What about Gavita Plasma fittings?
Good source of information
I have been using 10k metal halides aka H.I.D for supplemental uva and uvb spectra for over 10 years. I tried the uv t5 ho crap and it doesn't work the amount of uvb emitted is too low. In a 10k 1000w metal halide about 30% of the spectral energy is within the UV spectra. But remember not every 10k metal halide is made equal some will emit very low amounts of uvb and high amounts of uva while others will emit more uvb and maybe even some UVC.
NEED HELP, been trying to find the agromax pure uv light and it is not available anywhere at all anyone know where might have them in case i over looked something 2 or 4 foot is fine\
Here you go friend
HTGSUPPLY.COM
It's where I get mine in Michigan.
Thanks I looked there a few weeks back and they were out of stock
The question with the Agromax is does it produce the desired 1w per m² over the 3m² area? Or is it more like 3w per m² so over providing for a small area?
Was on the same page as you only so in my opinion the solacure would be best???
@@dreamweaverskennel2952 it's what I have gone with and am very happy with results. If your UK base Progrow.co.uk in Exeter do a set of 2 1 meter ones for about £155 and a set of two 1.2 meter bulbs for about £175 if your interested. 1 meter for 1.2x1.2m 1.2 bulbs for 1.5mx1.5m
Would be interested in a side by side but unfortunately Shane can't do that so will have to look to others for those kind of side by sides.
@@cjhification are you still happy with the 4ft solacure? It seems like that or the Agromax are the best options.
@@spider69420 there is a huge response that occurs within days of turning them on when used in flower.
What about hlg uva led bar?
what can you use for a small 70x70 cm tent? And has anything changed with UVB leds, are they better now or still almost useless?
Hi,
Fluorescent is still best, the UVB LED diodes are not efficient and are expensive.
Thanks.
Written on one box was for medical use only..fisrt thing I think of is medical marijuana
Hi would you be able to tell my lights to get for a 8 x 4 tent I want to not spend to much and I'd like to purchase from your company
Would it be advisable to hang these T5 agro bulbs vertically around the plants to give exposure to the bottom of the plant as well? Or best to let the light land on the leaves from above? If hung vertically around the plant it would side-light the vertical buds and kind of skip past the horizontal leaves, right? I assume you want the UV on the resin-producing buds and not so much the leaves?
how come u didnt make uv leds broads ?
He tells you in the first couple mins of the video. 1 led that is 0.2watts was 50€ and dosent do anything. That UV board would cost $100,000.00 to do anything.
.02 watts sorry decimal was in the wrong spot
great video but you are wrong when you say H.I.D does not emit any real uvb, i use 10k metal halide vertical bare bulbs designed with low iron glass from solis-tek for uvb / uvc output, i spoke with the manufacturer these bulbs emit 30% of they're total spectral energy within the UV spectra and they emit uva, uvb and uvc. also they're bulbs are made with low iron glass so that the UV spectra can pass through the glass.
Great safety advice
EPIC INFO GOOD SIR, many thanks
