I think you may mean activated carbon? For a carbon filter?

Did you go to the Herb collective they are on Young and they have promix. and I'd bet the have fans and stuff but yes Ebay much cheeper.

I use computer style fans I get from Bustan for 30 bucks, Or I started with fans from Active surplus they are the same thing and cost 15 bucks. 5 or 6 inch Fans, (they are on Bustans web site) However after half a years use they started to get a bit noisy. they push about 100 Cfm when they got noisy I replaced them with ones from Bustan same design same size just better quality. or quieter ball bearings

if noise aint a problem for you grab them from active surplus on queen st. 15 bucks each cant go wrong.

yeah how much soil do you really need>? thast alot of perlite and soil for the size box, You really just need 1 bag of perlite and one of soil. I carry that in my hands or on my bike. well my bike before it got stolen..

take it easy...

If you give me you safe email adress I can help you with your seeds situation.... I recently harvested some....
