That's a nice freggin carbon filter. How many plants do you think the thing can filter? Have you used any for your actual grow ops yet?
orangeman Reviewed by orangeman on . carbon filter -making of Assembly of a homemade carbon filter. I used two 8"-6" reducers, a 6" and 8" plug, 12 screws, chicken wire, door screen, some aluminum foil tape, and a crapload of zip ties. Only thing left now is to fill it with carbon that I ordered, and hook it up to my 250 watt attic fan, wooooeeee. Materials cost around $25, 27 pounds of carbon for $49. Rating: 5
