lol, I got that one! I loved it at first. Now I hate it. It, I am convinced ruined tow of my crops. I wrote it off as cal mag def cuz when the ozone gets real close to plants it burns it. However these just got splotchy but lived. Anyway, no yeild. Lol, man I was loaded on morpine to ignore it. Weird. Anyway, the thing is cool. Very powerful, but I learned the hard way, I thot I had it exhausting right outside but I lit a match one day and the airflow was rocketing behind me! A backdraft of titanic and secret proportions. Lol. Now I know why 7 gallons of soil go tme an ounce! Anyway, I took the top off mine too, and shoved it in a vent. I bought it used on craigslist for like 40 bucks and it was so old it was rusted. Lol, but as soon as I turned it on there was no mistake it worked. However I also owned another ozone too before I got that good deal, it was the titan ozone gen and I recomend that one if that is the route yu go. It has reflective material inside and is a little biiger tho. IDK about your setup. Just be careful, they will work! DOes get rid of smell tho.
