Hey guys this is a medicinal grow here. I had a 4x4x7 grow tent and 400w hps but it was too much for me I dont need that much space or power so I downgraded to a 3x2x5 tent and a digital ballast 250 w, its so much better in terms of space saving and power saving . I already have 2 ak48 in 5 gallon buckets , 1 airstones with two outputs , 1 180cfm fan connected to a fan controller , 1 small little fan for circulation and breeze , air cooled reflector and last some hygrozyme my savior. Right now i have a 250 mh light in there, in two weeks I will start flowering.
