Hi i'm Shane the founder of MIGRO and today we are going to explore how high i can get before my eyes completely close lol great video :)
😂😂😂
I knew it.HA HA HA.
Hahaha all I could think too! Need to get my hands on some Migro lights by the look of things! 😂🤣😂
😂😂😂💀💀💀
I need some of that eye shutting stuff.
Shane, you are AWESOME! I find your videos unbelievably helpful as a new grower. Thanks for all your work!
There's something very cool with the blend of colors in the background from the three generations of grow lights behind Shane that makes for a great visual and a truly classic video!
Awesome video Shane! Very informative, keep up the great work!
Hell yeah, my dude is so toasted, and yet provides good info, thank you.
He's hardcore balls out 😂
LOL
Adjust-a-Wings also make Super Spreaders to go with
with their high quality adjustable reflectors which
dissipate both light and heat more evenly preventing “hot spots”. Thus allowing for closer proximity to the canopy.
Thanks Shane, great bit of info!
Its amazing video, very much informative. Thankxx
Excellent. You've confirmed my current process. The foot tall seedlings are all doing well. I have my light at the top of my grow tent and I'll now come down a foot for a week and check again.
Yeah man we are all here for "medicinal plants in flowering stage" 🍃🌺😂
You're not growing medicinal flowers? ...Or you expected him to say "sick dank buds bro" ?
i don’t get what’s funny, thats literally what it’s called
SIERRA ERA people that don’t smoke think it’s super funny to say anything about weed, even if it’s literally not a joke. I think of it like how middle schoolers giggle over regular words
Bailey Gilbert couldn’t of said it better myself my friend, that’s fax😭
I wish to one day be as clever as you. You tube guidelines nahh your too cool to know about that.
A lot of good information👍
I usually adjust the lights according to stretch or heat stress, if the plant is showing signs of stretch I'll lower the light and leave it for 24 hours.
If it's showing signs of heat stress I'll higher the light and leave it for 24 hours, and a good isolatating fan blowing between the lights and the top of the canopy lets me get the light that little bit closer.
Had to review this one always great info Shane thanks a bunch
This is a very nice video, i totally recomend it. I've seen it various times throught the years, and still good information!
Just wanted to Thank You for your time for your videos
can't say it wasn;t informative......just thought life is more important than watching that all the way to the end. i hope it helped someone who suffered thru it
You speak soo calmly you make me believe every single word you say 🤔👏🏼👏🏼
So glad I found your channel. I have just brought a Mars hydro tsw2000. And wasn't sure.im used to HPS.thank you.
Aside from the so high/stoned jokes, thanks for the information! really appreciate it
Love the channel man thanks
Please do a video on the effects of migro cobs into a water column(aquarium w/plants). Would want to see spectral loss or gain, intensity loss or gain, ppfd at various heights... Thanks brother, for all of your helpful info!
Very informative! Loving how ur product is working effectively for the size! Amazing!
Little did we know 4 years later there would be a flooded market if LED, you should make a new video with this…..happy growing 🤙🏻
Great tip with the infared light
Lovely to see an Irish man on UA-cam who know it to a science . Excellent video Shane keep up the good work !!
Could you please do a video specifically targeting how high to set l.e.d. lights as we tend to have to mount led lights higher than hid lights as the led's tend to bleach out the top's of plants due to the light intensity I would suspect. Please elaborate on this topic.
With it being two years did you figure it out or is is the circumstances the same for any kind of light doing the diagnosis as shown in the video?
Thank you for the great info!
Hi, I m using the new citizen horticulture series lpw and lprb ...I can't seem to find a sweet spot. I have 7 50w COBs in 90cm...probably too much. I start at 70cm and finished at 40cm...amazing flowers but the plants seem to suffer a lot too. Do you have any info on these new cobs? Thanks a lot.
Really useful info! Thanks!
YES! My plants fried under the too-close lights last time just as you described. Tried fiddling with LUX phone apps but keeping Leaf Surface Temps just under ambient room temp may save me this time. I have an IR surface temp gun / baby thermometer that I can use! Thank you!!!
Any estimates on that lux use of the phone apps ?! Seedling/beging veg-end veg/flower?
Thanks Shane, this is fast becoming my favourite UA-cam channel, De Bacco University on UA-cam is very good too.
I just picked up a thousand watt HPS from my 450-watt LED the ballast for the HpS has air cool my LED was about 12 in but I'm not too sure how far I should put my thousand watt
Very informative!!
Hi Shane the 1200 par you mentioned is that a good guideline for all stages of growth of a medical grow in other words from seed to harvest I have the cheaper meter you mentioned and I’m about to start using it on my next grow for the first time with your Migro 600
Question please, I have a vipar specter 400. Is there a formula or a calculator online where I can figure out how low I can hang the light and dim it to save electricity when the plants are still small? Thank you
Another great informative and useful video thanks for your time and service's
wow, this video is very well made man...
very helpful and clear , thanks
Such quality info here.
I don't know the par or ppfd of the 10watt 806lumen household bulbs with the domes removed but they are good at 5.5 inches above chilli plants
Very informative. Good information which newer growers will certainly appreciate.
Thanks. Everyone check out ISMOKE. Great web magazine and UA-cam channel.
All good info, i like it! thnx
Migro, I have a 1000 watt tolys led full spec light. What distance should it be hung from the top of the canopy please sir?
Very interesting video but I really think room environment, genetics and plants different stages plays a big part in how low or high you should go with your lights
Awesome information thank you
Wow great information
wow what a great video and channel! thanx. all the answers about grow lights in one place
What size grow tent would you need for a 48inch shop light using florescent bulbs
If I was using a lux meter on my phone what numbers should I be showing for best results in a 4x8 grow room using K4000 AGLEX IN hanging them to the right height 🤔
Thanks for the great info ! Can you please make a video comparing a 600w hps adjust a wings vs air cooled hood so we can know how high the air cooled reflector can be to optimize light spread ?
i have family in dundalk i love this guy. love from the uk
hii there.
do you think it is possible to grow in an space with a max height of 120 cm and if so wich led light you recommend
thanks in advance
Hi explain all nice but very enginering way. What you will prefer for cfl ligt 200w how far the light should be? Thx for help . Stay safe🙏
Can I use an HLG Scorpion Diablo for seedlings? It's hanging at 7ft from the floor.
Hi Shane a quick question I have 5 lights 3 are 600w and I have one 1500w and a 1000w, because they are different I don't know what distance I should hang them, my gut instinct is telling me to hang the highest wattage higher up and the 600w lower, any info would be much appreciated please.
This guys wrecked
I Love it 😂
He's so stoned, very good video you got to love the Irish people.
Aren't we all "so stoned". It is the way of my walk daily.
Even Conor McGregor? IV heard two woman at least have been compelled.
No shade on the Irish or Shane, I just couldn't miss this opportunity to educate/insinuate against the MSM silence and UFC Disney lawyers power. He needs disowned and his bits fed to the pigs.
SpliffHound 420 what the actual fuck are you even going on about?
🤘🏻
Damn good video. Think my seedlings are getting just a bit too much light... just a spot of color on a couple of their leaves. In going to adjust accordingly. Thanks 😊
But light intensity in LED could also burn the leaves without necessarily an increase of temperature, so the method of messuring temperature would be better with HPS?
how close should a 630w double ended cmh light be? thanks in advance. love your videos
he shows you a couple options to measure it yourself.
Maybe measuring out and tattching a dangling a streamer or bob-wait line on a string from the light so its a reference to the top of the plant or canopy.
I'm growing a BLUEBERRY CHEESE OG and I need to know have I got to feed her both bloom and boost together or boost only as it's my first auto grow.
I love how high you are in this
I have a Rockpals 600W LED grow light with vegetative and flowering settings. I currently have 1 week old seedlings. Can you advise what is the optimum distance and power setting I should keep them on in the seedling stage? Thx
They have their own advice online, best to follow that.
What do I do if my plant is larger than 10cm (just the stem)?
Ive got the kingbo 2000w led. I had it 24 inches about the top of canopy but noticed the tips of my leaves were burning and some leaves were feeling dry and papery. Would you recommend hanging about 40 inches ?
I would be putting the light at the top especially if you haven't got a dimer.
Absolutely blazed 💖
Could be bright af in that room and no glasses lol
Are lux or FC measurements of any use with grow lights? With LEDs they don't give off much heat so surely that's not a reliable way to suss the height?
Lux measurements ar not accurate for photosynthetic light, they do not measure red and blue light properly. As LED's don't give off too much heat they can be closer to the plants. Your skin is a good guide to physical heat detection and when it is too hot for life.
Super toasted,luv it
how high approximate if use a cob 110 led
i have a lumatek 200w for which phase is which % 25,50,75,100?
that sure is a nice video things are looking up for SSG real glad for you Rusty keep it pumping out them Beauties like that yes sir Rusty Shackleford the monster grower hehehe later my friend
Can you link the tools you use in this video please.
There are two par/ppfd apps for Android that work seemingly well. Any have a real par/ppfd meter that can download the app and text it's acuracy?
thank you i had my light to close and my leaves burn thank you for this information cheers from the bay area california
Good infornation
I've noticed that you never use parabolic reflectors! I use a parabolic reflector with a 1000w HPS and find that I can put the light as close as two feet above my plants depending on the strain, sativas seem to do the best with the lights less than three feet away. also I noticed you don't use defusers with the adjustawing any particular reason? they really cool down the hotspot and allow the light to be closer to the canopy!
I believe that LED's have their place but if you want to be productive nothing replaces metal halide and HPS for growing hemp.
2.9 umols the new bar leds are now.
I have a 1000w led and a 150w hps grow light but how should I use them? Should my plants be under the led mainly or hps cause I feel like the hps is working better and the led is making me question the buy
I have a 1000 w and I’m growing 2 so far ..LMK IF YOU HAVE ANY LUCK
So what his the Gold rule for Different Wattage`s #or is it up to the Pearson growing it ! Cheers mate
Have you ever done 4t5 4X2 vs Mars hydro ts600 as far as for veg and par
Nice break down.
Hello Mike, I’m going to grow mini orchids in a terrarium. How high should I hang my grow lights?
Mate are the PPFD meters on mobile phone any good are they accurate enough please mate 🤜🤛🇬🇧💨
I have a 4 x 2 x 6 grow tent with a 1000 watt LED I have two clones in the leaves are turning yellow.. I believe they're getting too much lightif so what size LED light should I get to this size tent
First thing you need to do is check is how far above those clones you have the light. That is a lot of light for a 2x4 tent and if your LED is closer than 36", I would expect it to burn up pretty quick. I have 600 watts LED in a front closet that is not quite 48" wide where I grow lettuce, basil, jalapenos, cilantro and if I go less than 36", I can expect all of the seedlings and greens to just dry up. The lights are 19" above the top of the jalapeno plant and it is going crazy. With flowering cannabis I have gone down to 12". I have used 3 different brands of LED and its pretty much the same.
Happen to know how far for the 315 growers choice? 315 mode as well as “super lumen” new to the light and tips or links to a video would be much appreciated!
I just got one for test. Comparison CMH video out soon.
Thank lots brother...
Very nice
My name is shane also lol great work bro keep it up please
Finally a good test of HP's
If you get a light track you I can lower your light also will cover more area
With leds it’s the Watts marshydro 300w =130w you can get really close from 1set leafs to kick start her then rise light as the nodes grow for more coverage . mars hydro pro 2 80 400w =200w I do 20” as it stretches rise the light up 2” Many people give up and moan on sites once you master the distance you be happy bunny
How do u find the mars lights? I heard a lot of bad shit about em?
Hey Shane , can you please test different kind horticulture lights from led tech ? Its a german product . They have different systems . System250 V2 , they have the Zeus 308XT Bord . And its a good Produkt . Different spectrum in every Typ and modules with different led chips . There really good and didnt cost much . Made in germany ;)
What fan model between lights ?
as close as is possible. put your hand above canopy have light lowers til you feel to much heat, light movers are a good investment
Leds are not problematic about heat but about light intensity
What about quantum boards? How much lower can you hang them?
HES LIT UP
So... what distance for a 300w LED (ufo) from the plants? thanks!!!
Awesome
Wells
Always the best
I wish someone would do a video on the lumatek 630 cmh.
Can I just adjust an LED light as low as possible so the footprint appears to cover the plants and then adjust the intensity knob to achieve the desired ppfd based on my iphone using photone app?
I am trying to figure that out as well... I have a ac affinity 400w Ionboards44 and they recommend this n that but for me I have it on the lowest possible setting for light when they are seedling and going into veg.. and let the plant tell me.. they'll start praising or reaching up to the light in a good way not that stringy stretch.
You can use app make sure it's calibrated right a phone camera can only do so much but for budget purposes gives you an idea at least what range you in
