So if my dimensions of my box are 4.5x4.5 maybe about 6 or seven feet high, would this carbon filter scrubber be enough power to clean my air efficiently, I really don't want anyone to be able to smell it outside either as i don't live in a great area (they'd steal it). Oh and this might be a completely dumb question, but im new to growing, so by these dimensions of my box, how big should the passive air intakes be? Passive just means puttin a hole in the bottom of the grow box right?
