Hey GC, Using 2 Rubbermaid totes stacked on top of eachother for a stealth grow, like the one shown below (minus the lids, of course). Wondering if a 60 CFM fan will be enough to push air through a DIY carbon filter, or will the fan not be strong enough for the backflow of air? I imagine the carbon filter makes a fair amount of resistance. I thought for the tiny size of the growspace - about 1.5ft wide x 2 ft long x 3ft high - 60 CFM would be fine. I know people dedicating entire rooms to growing and they only use 440 CFM. CFM = cubic feet per minute of air being pushed out, so if my grow space is only about 9 cubic feet, surely 60 Cubic Feet per Minute of air would be plenty. Just concerned about resistance from the carbon filter. thoughts?
