I acquired a commercial Sonozair ozone generator .This one cost about $900 but It was given to me.I want to put it in my grow room and duct the 2 inch exhaust port outside behind the house and conceal the tube by covering it with some junk .The machine is variable and will deodorize an area up to 15,000 cubic feet my room is 8 feet wide 6 foot deep and 6 foot height.(Walk in closet).It should work great
