Carbon Filter Placement

Does it matter where on the box you place your carbon filter. For my box the bottom would be the best place, but i thought that all the hot air rises and that might be a problem.

Any advice THX

i placed mine totally outside of the tent to give me more room inside it

I keep mine outside my flowering room but inside the bedroom the closets are in.

I'm gonna attach mine directly to the box so . . . . . any advice there??
