I know a carbon filter is the best option but the problem is that the walls in my closet are quite thick and I can't cut out a hole to install an exhaut fan. I use t5 and cfl and the heat is not too bad so I am able to grow without opening the door too much. Right now, the plants are only 2 weeks old and doesn't smell at all.
I have a hepa air purifier equipped with odor controll air filters. If that is not enough I was thinking about buying a tub of ona and a pair of odor control Ti coated CFLs.
Do you think this could work?
