Hey, I am using roughly a 4'x3.5' area. How far from the top of the plants should a 150W HPS be? I have about 150W of CFLs to supplement as well, around the sides of the plants.. I dont have a cooler, however the light and the reflector says ventilated so i hope that helps. I have a fan at good speed to circulate and cool the air..Is it necessary that I get some type of cool tube or something?? Thanks guys
It really shouldn't be hot enough to disturb anything... I would say 12"-16"(no further) away from your ladies.
