You need a temperature probe under your light at the top of your plants. Don't let it get to hot. Using HID lights 0-12" away is all the same lumens.
Zandor Reviewed by Zandor on . burning right i got myself a metal halide lamp & the plant was about 12 days old, i kept the light about 2 inch's away from the top of the plant & i had a fan on it constantly when the light was on to keep it cool, but the plants leaves still fucking burnt & if i gota more powerful fan then it would blow the plant away, any ideas on how to keep it cool :smokin: ?
