I came across this idea on another site here. He uses 2 small rubbermaid boxes one larger then the other. he cuts a hole in the top of the large one and cuts a hole in the bottem of the smaller one and covers that hole with screen. he sets the smaller one into the larger one. seals and fills with 1/2lb of activated charcoal then instales a fan in the cover of the small one. holes on the side of the big tub and some duct...bam carbon filter.
ok so my question is what if you scrap the larger tub and ducting and just cut a whole in the top of a grow box and set the smaller of the tubs (or you can just use the larger tub for this) into the grow box? an extra fan maybe? sounded good to me
