MMMMMM that looks good this will be interesting.... Yeah my 400w hps is about 4 or 5 inches away from the plants cause I want enough light not only hit the top of the canopy hard but also the bottom..... I do use mylar as well tho but you know what they say the more light the better, I would invest in 1000w but I dont want the elec.bill to get any higher or worry about them ever finding out
