So it seems like all the carbon filter set-ups I've seen have people running their exhaust air through a carbon filter and out of the room. My question is, if I have a completely enclosed room to grow in is there any reason to actually exhaust the air that comes out of the filter, or can I just have a fan sucking air from the room, pushing it through the filter, and then going back out into the room. That would actually be more effective right, because all of the air would continuously be filtered? As long as you are sure to replace the carbon as often as you need to...
