Big bang grow using 90w led

sorry guys, but with a good light, closer isnt better... in fact I would say almost the opposite... further the light and you get a better blend of spectrums
Sounds spot on to me. This is what the manufacturer of the LEDs i'm looking at recommends (Pro Source Illuminator)
[h=3]Vegetative Growth[/h]
Model Light Distance from Plants Maximum Area Light Footprint
90W 12" - 24" 16 sq. ft. 4' x 4'
180W 12" - 36" 25 sq. ft. 5' x 5'
350W 18" - 48" 30 sq. ft. 6' x 5'
700W 24" - 60" 63 sq. ft. 9' x 7'


[h=3]Flowering & Fruiting[/h]
Model Light Distance from Plants Maximum Area Light Footprint
90W 6" or closer 4 sq. ft. 2' x 2'
180W 6" - 18" 9 sq. ft. 3' x 3'
350W 6" - 18" 16 sq. ft. 4' x 4'
700W 10" - 18" 24 sq. ft. 6' x 4'

So how close is too close? So dont worry about bleaching unless you have a solarflare? What a interesting post.... :D
Exactly... surface of the sun, solarflares are intense.
Most all LED panels are currently 3w not 5w so yes unless you have a 5w panel (solarflare/also blackdog), dont worry about bleaching with the 3w ones.

Now I don't have a chart or anything lol, this is merely my experience using LEDs a few years now with my specific panels.
The lumens/intensity dropoff is exponential with each inch making for only ~12-18" of optimal penetration using 3w panels.
5w LED panels (Solarflares/BlackDogs) have a good ~20"+ optimal penetration.

Common sense is if your hand gets too hot under the lights, its too close for the plant as well.
Im aprox. 6" away using my BlackStar... for my solarflares 12+" to avoid bleaching.
Those are all flowering distances btw.
