Garden Knowm Reviewed by Garden Knowm on . My gift to you growers These two items will save you a ton of money. Odor control: I'm using a small air purifier about the size of a shoe box in my closet. I have 3 giant plants all 3 weeks into flowering, no smell, zero. It has a ionizer, I dunno if that helps but forget expensive carbon scrubbers. This works better. Exhaust fan: Check out this baby, 200cfm, 54 bucks.http://www.homedepot.com/cmc_upload/HDUS/EN_US/asset/pdfs/a1cd341e-6743-4e3f-862d-723e80253d45.pdf If you can't open pdf's, go to Rating: 5
