first grow and woundering how far a part should my lights be for a 18x18 room with 1000 HPS on the ceiling and I got 6 of them thanks looking to grow 25 plants
hello wizeman that`s a big grow cool. i dont know anything about the 1000wat light coverage. but i would lay them out on the floor in the grow space and evenly space them out from there to give you the max cover. regards
