when i saw that pic of the led 1'' off the tops it kinda scared me, if that didn't burn the plants then I wouldn't have much faith in those lights, just sayin, even the crappiest of LED's ive used have needed to be at least 6'' but more like a foot away for the sprectrums to blend and the plants not to bleach. just personal experience tho. how long was the light that close to the top of the canopy?
