do you need 2 exhaust fans for a grow tent? would a 250 cfm cool a 4x4 grow tent?
ok but do i need a fan on the duct pumping air in too?
Yea, with the Fan Sucking air out of the tent, it automatically sucks air into the Tent via the Bottom Flaps, so no need for the second fan.
if you use another duct for the intake you can make it light proofwhat flaps would that be? what about when its time for the 12 off? wont flaps allow light in? just asking cause im in the same boat as the op....
