    advice on ventilation

    Hey guys. I am building a SUPER stealth grow room...and upgrade from my plywood grow "box". Ok, it's 3' wide, 12' long and 7' high. I am getting ready to insulate with 1' foam and spray foam. I figured that I would filter an intake, then filter an exhaust. I had a 4" carbon filter/fan in my box, but don't know what would be enough for this little room. BTW, I haven't weighed, but I got 5 full quart mason jars from my 4 plants. Pretty damn good smoke too!

    I recommend what I'm using - Vortex Powerfan - super quiet, super powerful - if interested buy a variable speed controller as opposed to a low/medium/high 3 speed controller.
