OK. So I will be getting a Yield Master 2 Supreme 6" Air cooled hood and a 6" inline fan rated @ 435 cuft. I will have a passive intake from my garage into my room near the floor and then exhaust back into my garage near the ceiling. My room is about 5' x 5' x 8'. I will be using a 1000w Harvest Pro Elite ballast and Hortilux HPS bulb. Other than the passive intake it is for the most part air tight. I will have a heater to keep temps at the right temperature when lights are out. The room is in my basement, which stays fairly cool, so when my lights are on I should be fine with the temps. My question is this, how do I run the carbon filter, fan, and hood? Like this? ..... Filter===>Hood===>Fan====>Out to garage.... (arrows denote flow, I know pulling air thru filter is better than pushing it.) Will this setup work to cool my room? Thanks for all the help and suggestions in advance guys!! I am fairly new to all this so any help will be greatly appreciated!!
