Do not use an ozone generator in the same room as your plants, it will kill them. Buy some active charcoal from the pond fish store (it's cheaper there). Get 3 furnace air filters and a good fart fan. You can make a scrubber with little effort and it will handle all your odor problems for 6 to 8 months then you just change the charcoal. I use 6 pounds in 3 layers in a 7x7x7 sealed room and it works great.

Peace
