hey dude thanks for the info, i dont know if you have seen them, volksgardens it is a rotary growing machine, i have always used envirolites, and really want to stick to them, because everything i heard about hps is that they run at ridiculously high temps, anyway this guy using on of these machines uses a 600w hps in the middle, i would like one of these machines but dont want to use hps.... i was thinking of maybe like 3 200w envirolites on top of each other in a triangle shape
