I added a cheapo home dePOT duct booster fan to my passive intake, making it an active one, and a length of duct that directs the cool fresh air right in among the pots. Definitely an improvement, and a pretty inexpensive one.

lol I see you have figured out how to activate your rep!
stinkyattic Reviewed by stinkyattic on . Question about intake? Got a few cycles under my belt, but I am for the first time running into some temperature problems. Right now it's 81 in the room, trying to keep things down. As of now I only have an open circuit that is taking warm air out of the room, through the lights, and into the attic via my Vortex fan. There is also a hole in the floor that would be perfect for pulling cold air in... is this the passive intake? In a nut shell I am proposing that I attach some ducting to the whole in the floor Rating: 5
