i am using a fridge. top is for veg bottom is for flower. biggest problem is it hold extreme heat even with floros. i have intake and exhuast in both compartments. a positive is that it is very reflective so light can be minimal. this is my first go at it. i am using 26 wt floros i have 4 on top and 10 on bottom. i am in the process of installing a scrubber underneath so it just looks like a fridge. beware that when you open it with the lights on it looks like a football stadium at night so make sure were you put it is out of view. i intend to up grade to 150 wt floros for flower in my next grow. once i get my cycle down i hope to harvest about every six weeks
