  1. 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

  2. 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 ?

  3. great video way too fancy my friend. I wont speak for everyone but I want to say most medical patients that are thinking of growing Cannabis are not going to be even close to equipped enough to have this kind of tech. There must be a more simple way of testing and measuring and what happens when the plant is in stage 3 vs stage 1 or 2 ? what is a “watt” and all that. I am not clueless but I love when people talk slow and use little words. lol

  4. I seen a sativa non auto plant reach full flower stage in a closet with just 3 x 60w led goose neck lamps that are double heads 2x30w on each lamp no nutrients just water and some banana fertiliser for potassium

  5. 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 🙂

  6. 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!

  7. You suck stop with the videos you clearly don’t know what your doing you rumble to much a distance in inches maybe feet would be very useful but you’re too stupid you made a long video but nothing so thanks for wasting my fucking time you piece of shit

  8. How fucking boring are you 😂 watching precious seconds of you with the pastys 😂 honestly big fella 😂 your so boring I fell asleep while I was asleep .

  9. i guess my chinese led strips idea wasnt so bad…i can put my plants really close and they seem to love it.im gonna reinforce it with a few 10w cobs though so that may change things a little

  10. 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.

  11. 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.

  12. Hi , very informative video , and great lights fair play . What would you suggest the best hanging height for seedlings and veg would be on a 600W (240 actual wattage) Cree cob ? Tried some at 28/30 and it fried them … Cheers ! 🙂

  13. 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

  14. I've never had a problem…I've had 1000watt universal bulbs 6 or more inches from the centre over a 2 to 3 foot plants…control ph I do solely pro mix and do water them everyday….no light is hotter than sunlight

    .so how does any plant survive outdoors?? Ph ph ph control especially indoors.

  15. This is a very interesting video and have found it very useful, thanks Shane!

    What if the leaf temp is only 1 or 2 degrees above the grow area temp ? is that still a reason to raise the light?
    ie if room temp 25c and leaf temp 26c just by one degree hotter is that really a reason to raise the light ?
    And if you have raised the light to its maxium height is there anything else you can do to stop plants from having too much radiant heat ?

  16. 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!

  17. What about the use of my light rails? My LED's are always moving either north/south-south/north or east/ west-west/east. I've designed a turn style or inverted lazy-suzan that allows me to rotate the whole light assembly any direction I want thus changing the light rails to allow light penetration and never a hot spot or high leaf temp no matter if I'm 3' inches above my plants. How much PAR can I allow them now without damaging cell structure? What are my plants new thresh hold (PAR numbers)? Am I on to something or is what I'm doing a bad invention and just a novelty? They are getting PAR readings of 2600 but its never at that for more than a couple of seconds. The plants do experience time with readings of 200 PAR when the light panel has gotten its farthest from that plant but then they change direction and come back . I don't keep them that low ALL the time because I don't get any stretch. I currently have Plants that are 8" tall and 10" wide and solid green because the foliage is so dense. I just came up with this turn style idea 2 weeks ago and the plants are only 3 weeks old from seed. Long story short is how high of a PAR number can they constructively put to use? Have I just created new maximum yield numbers to strive for?

  18. Mate one advice. Get a fucking drink before you start recording 🙂 good luck couldn't listen for long though. All I have learned is what to buy to check if my leafs don't burn. Well I knew that already !

  19. Anyone !: have a small grow space 1.5 square meters=16.15 square feet. 122,400 lumens using LED screw in bulbs white & yellow. 21 Autoflowering plants.Offhand, in general am i using too little or too much light from bulbs close to the plants but not too hot? Thank you.
