Thanks everybody!
HitTheHazards... Yeah, I only have an upper exhaust fan and lower intake with no intake fan, I didnt think I needed one. Stay posted and we'll figure this out...
TG.... hey bro... it's rated at 80 cfm, I thought that would be good enough, at least a step up from the axial fan. I thought about a variable speed controller...will that make the fan go faster? or just slower? I dont have central air, so no ductwork, maybe heat for winter...
justanotherbozo... I had a homemade cooltube on it that just drawed air from the closet to exhaust, it didnt have it's own intake, as you can see there's not much room for anything other than the light, no difference... thanks
GanjaLover... my plants always seem real nice and dark and healthy in the cool veg box... then when they go to the hot flower closet, they seem to loose that nice green luster.... thought it's probably the heat, and when the door is closed it's creeps into high 90's,not much difference even in winter.
