Indoor gardener here enclosed 10 x 10 ft room 8 ft ceiling closed running soil,co2,BioCanna feed schedule Organic as possible..Like most growers we sometimes have issues with spider mites and powdery mildew so I was checking out Ozone generators since I have had one laying around for years that we used while living on our boat . It turns out that if you do not go overboard with how much you put into a room that it can be very beneficial in killing mold spores and sanitizing surfaces.. Does anyone have any experience with this ? Thank you and Happy Growing ..
