Why go ozone? carbon filtration does it so much better and you can go easymode and get a stand alone air scrubber type unit that also has a hepa filter. I'm guessing youre already using some form of carbon filtration in the tent itself, theres no reason to use ozone over carbon. Just google air scrubber with carbon and anything u see there will do a better job than ozone ever could as your second line of defense for odor.
Even honeywell makes carbon prefilters for any of their common as hell air purifiers.

That on any unit even if it isnt speciifically made for carbon, will best any ozone generator, for $15.
