i like 600 watt air cooled lites.1000 wat has near double heat, and down here makes it harder. even if air cooled,,besides the 1000 lites are way over rated.600 cost the same or more, because thier the best way,easy air cooled tomaintain.mine . mine are going crazy now and i drop the lite at 6 inches and the temp at the canopy is 72F.closer is as good as vertical trust that .plus you may need some room to move around huh.this feminized blue cheese i see is the way to go, , i never had plants gettin this size so early , by the ebnd of the day they near doubled from this morning,, the 9-50-30 really did the job,,,, then we'll drop the magnesium levels and get some real purple in the las 2 weex, ,,,,, i see your a brother,lol.
