Activated carbon has to be replaced to stay effective. Usually after 2-3 grows, it's starts losing effectiveness and will need to be refilled. So, it's good and certainly effective... but it's not the only way to go. Some of the prefabricated filters can be insanely expensive.

Here's a pretty cool odor neutralizer that's inexpensive to build and maintain. They're really easy to make, too. Made one last weekend just for the hell of it.

How to build your own inexpensive odour neutraliser...

Never used Ozone before, so I don't have much to say about it. Just don't keep it blowing on your plants, as I've heard it can damage/bleach the foliage. Take care.
Mr. Clandestine Reviewed by Mr. Clandestine on . effects of ozone hey all, i tried to search the site but couldn't really find much info. in a fit of unsatisfaction with my local hydroponics store and their outrageous prices, i started my own hydroponics supply a while ago. anyways, my supplier doesnt have much to choose from in the odor control department. Theyve got Ona products and blue air ozonators and airballs. Ona leaves this weird funky smell. I guess they work by replacing questionable odors with their own funk. does anyone here use ozone? ive Rating: 5
