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!
