I started out w/ a mini cool cab and after 3 grows i relized that the cabinet at 46" hi 20" deep 32" across it was too much work for too little yield ,, i then set up my grow room which is 8 1/2 'x 12' withf 2 600 watt w/hortilux bulbs and cool tube reflectors an in line fan and a portable 11000 btu a/c temp are a reliable 72-74 degrees even in the summer here in the desert.. my first grow was hydroponic in 6 5 ga dwc wasnt very successful because old a/c failed and they suffered heat stress ..chging the res wasn't easy for me since my mentor said it shd be chged every week to ten days I decided then to switch to soil and im growing 10 trainwreckplants that are coming along great.. im in day 28 12/12..using GH grow + flower + micro nutrients and bat guana and molassis...
