Ok so for the last few days iv been wracking my brains and yours here on 420 for the best way to control the odor in my itty bitty grow cabinet i am soon going to be building and i'v finally built a prototype carbon filter 
.
iv taken an old 25gram plastic fish food tub and cut a circle in the lid and in the base slightly smaller than the pc fan i have wired up, then i used electrical tape to secure the fan onto the lid so it sucks air through the tub but i can still remove the lid and the fan with it when the carbon needs to be changed, then what i plan on doing is cutting 2 pieces of carbon filter sponge into circles to fit inside the tub, the first one will go just behind the fan, then il add a layer of granulated activated carbon and fill it until i can just about squeeze the second piece of carbon filter sponge on top of it like a sandwich, fix it to the outside of my grow box near the top, make sure that its air tight around the whole thing and HEY PRESTO A CHEAP CARBON FILTER, i'v already tested it by stuffing it full of regular aquarium filter sponges and it's sucking air through them very nicely 
just a few questions...
how often will i need to change the carbon in it to keep my room daisy fresh and will this work lol? i plan on making a small intake hole near the bottom of the box to keep it all at a negative pressure to ensure that the only air leaving that box goes through the filter.
let me know what u guys think as i'm off to smoke a doob
