Odor control?

Hey, I've got about 9 White Castles growing in a hydro set up under a 400w hps and two 100w cfl, and the odor is starting to become very potent however, I would like to know what is the most effective (and relatively affordable) solution to the odor coming from the grow room. Thanks guys.

I havent tried that.

I use a carbon filter, a 150. They are prolly the most expensive filtration system but pretty much guaranteed to work. You can get them for less if you can find them used. I got mine off craigslist.

thanks, how often should the filters be replaced?

It's lasting around a month and half on average so far.

The smell of flowering cannabis can sometimes overcome any filter, or ozone.

Thats why you need to grow something with low odor.

Alot of people get busted because of it.

Good luck.
