Another Quick Question

I have 600w hps lighting in a grow closet with a wall mount fan and Mylar all around the walls.

how close does the plant have to be to the light without burning the leaves ?

as close as you can get it feel the heat with the back of yer hand... about 16-18 inches should do...... if its too hot for yer hand its to hot fer your plants

the back of the hand.I keep my 400 watter 8-10 inches from my plants,and it is fine.

sounds good to me .
