I just bought http://cgi.ebay.com/Hydroponics-Tent-48x48x78-Hydro-Cabinet-Grow-Budd-Box_W0QQitemZ320421978780QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item4a9aa3629c&_trksid=p3286.c0.m14 4'X4'X6.5'on ebay.

I'm trying to figure out the cheapest way to vent it. I'm going to incorporate http://forum.grasscity.com/grow-room-design-setup/384051-another-diy-carbon-scrubber-less-than-40-a.html into it. How much cfm do I need? And whats the best type of fan for me if i'm looking to spend under 100 bucks. And what else would I need to attach it to my tent? Thanks for the help. I'm such a noob right now, I just want to get it right. Thanks in advance for any input! http://cgi.ebay.com/Hydroponics-Tent-48x48x78-Hydro-Cabinet-Grow-Budd-Box_W0QQitemZ320421978780QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item4a9aa3629c&_trksid=p3286.c0.m14
