Converting a 5x5 closet into the space. Running a HLG LED 320W QB for ideally a 2x4 grow space. First two strains planning on growing are Blueberry and Gorilla Bomb. Since growing in a closet the height is much bigger than a tent so that's not really an issue. By keeping them 1ft will that be enough space between? How many inches from the closet wall is needed? Also is their a way to make the door only open halfway?
