air circulation is important...but equally important is that it be fresh air circulation not just the same stagnant closet air...i'd sedgjest figurign out how tomake a ventilation system where fresh air would be pumped from the outside of the grow chamber pumping air in and also the fan inside of the grow chamber pumping air out...best of luck
