Napa if you have a Walmart, go there and buy a Febreze plug-in Odor eliminator with carbon filter for $15 and the replacement filter for $5. Also it comes with night light on it or without, plus an indicator when to replace the filter. I read that it really works and with the size of your grow, it should work with no problems. I plan to get one for backup odor control. It lasts for 5-6 weeks if you plan to have it running 24hrs daily so buy the $5 replacement filter. I would have mine on a timer for the same time as my lights come on, not running 24hrs.
