I'm about to start building my first grow box (in a speaker, CFLs) for my first ever grow. I'm coming into it a bit blind, but have been following links around different forums for a few days trying to pick up some information, and taking loads of advice from rollitups FAQ. However, I have run into a few questions already, and am hoping I can get them answered, although I suspect they may be questions of the frustrating type, please be patient, I'm awful at this sort of thing.

1) For a carbon filter, I've seen some instructions for how to make my own, but I was wondering if taping an activated carbon filter (from a fish shop or wherever) over my exhaust would be adequate for odor dissipation.

2) For ventilation, do I need more than an exhaust fan? I plan to rig a computer fan for exhaust as it's not a terribly big box, but was wondering if an intake fan was requisite or if I could just mount a length of PVC with a 90º elbow for air intake. Would this work adequately, and would this need its own carbon filter to eliminate smell permeation.

I'm very sorry if this is covered numerous times throughout the forum, I have looked.
