Ozone, Oxidizers, UV
Ozone generators are amazing tools for indoor and hydroponic gardeners as long as all proper precautions are taken. Ozone generators and UV filters can help remove and neutralize odors, killing molds, staving off insects, and disinfecting entire empty grow rooms. As a general safety rule for your growing environment, you should not be able to smell ozone (rain-like smell) while it's switched on. If you do, you may not be exhausting enough out of your grow room, or the ozone generator is too large for your space.
