Hello Everyone. I am running a 600W air cooled hood growing in a 3x3 tray with drip to waste watering system. I was just wondering how many CFM's should my fan be.? I plan on putting a filter to control odor becuz i have to keep it as a Stealth grow. My grow room is a shed 6'wide by 5' deep and 5' tall. Also what kind of filter should i get? dont know much about the whole filter thing. also how would i setup my venting system as far as running the ducting to the hood and the filter? anykind of input would be really appreciated! Im eager to start growing just need the right info. THANKS
