Hey I've been battling powdery mildew this whole year on and off. I am sick of it surprising me here and there so I bought an ozone generator to keep it dead. It is called the OZN-jr and covers 1000 cubic feet. It runs in 10 minute intervals, 10 min on, 10 min off. I am in a 4x4x7 DR120 grow tent and need to know if it is safe to run this ozone generator. I don't know how to control the ozone level let alone monitor it. I need to kill off this mildew but don't want to harm myself or my plants in the process. My tent is in my bedroom so I'm sure the ozone will be exhausted right into my room where I live, is this safe?
