why does everyone hang leds so high? Mine are about a foot above shortest plants. 2 inches above tallest. No heat means closer lights no? Dont you get more out of them when closer?

Light bleaching, if you put decent led too close to young plants you can bleach them.

Ive got one that keeps growing into light, she was about 8 inch clone at start now over 3 ft, l set light 12inches above canopy, cant raise or lll leave short plants in dust.shes about 1 inch from bar on more than one shoot. Other than a low ph shes not showing any sign of stopping. Thought my light is decent, commercial fixture, good company. 1482umol m2s not good? Or decent? I do know a thing or two about light depreciation, every foot gets cut to half type thing, l want everything l can get out of my light. Just see lights rated not much higher than mine 3 feet away and dont get it!
