I just started my grow room yesterday, I have a 600 watt setup. My closet is 7 1\2 ft. tall but the closet its self is 2 ft. wide and 7 ft. long, my walls are also white, it got extremly hot in there i woke up in the morning and my soil was dry to the crisp..my lamp NOW sits 2 1/2 feet from the bottom of the soil do you think this is still to low ? ..I planted my seed yesterday ..do you think it damaged it? Also what do you think would be the best ht. for my light? i dont want to damage my soil ...
