First off, thank you for the reply....
I think I should be able to give it a decent medium on the lightning, my biggest worry is about the ventilation, crawlspaces don't seem like the best area in the world to grow but doable but then again I have no idea why I asked....
About this carbon filter how do these work? Would I just place them on the ceiling around the vents that go to higher floors? I remember someone posting a url(will link at the bottom of the post) for a ozone generator air maid would something like that work? Or would I just be better off with a carbon filter? About not using upstairs with a grow box...thats really what I'd like to do in the near future, but atm theres really not alot of room, still have alot of unpacked boxes and currently don't really have a nice grow box or wood around. Would like to get one of them closet type setups from lowes/home depot when the money allows it. The link for the ozone generator is http://www.kalyx.com/store/proddetai.../2740/file.htm
