How To - Carbon Filter

[texas grass]

Hey, great how-to post here,

I'm planning on making one of these in a little bit but I have a few questions.

Where the hell can I get the activated carbon?

and

Would a carbon filter be any use for growing in a walk-in closet?
Would I just put the carbon filter in front of my fan?

Cheers!
