I too have browned some hairs.
I am not too worried yet, but I am still in veg.
Was going by the "keep the lights as close as possible" method.
Usually 1 inch with my tops in between the bulbs.
2 Fans blowing on the hood, my room temp. is 25*.
Guess I have to much radiant heat or lumens /sq.ft for that idea.
Going to 3-4 inches.
