APT Grow.

So guys...I've been living in an APT and decided to grow again. I have a closet that's about 5 ft wide 2 ft deep and 8ft in height. I've grown this particular strain before, and I must say it's not really that pungent. Even while harvesting...it popped, but it wasn't really that pungent. With that said what are some good alternatives to a carbon filter? I'd like to install one...Just really don't know how/where to install it with all that open space. Landlord seems pretty cool. There's a guy two floors above that has two plants, and the landlord not only smokes with these guys...he regularly checks up on the plants. So im not to worried, especially since my objective isn't to sell. Anyway I digress. I'll be working with 4-6 plants any ideas for odor control?Ona gel? I was also thinking an Airwick automatic time release spray deals. AIR WICK - It's good to be home®

aright guys... peace.
