No doubt, and I generally only used mine to "scrub" the room after I left, only takes about 1 minute to "clean" the room. You see, It tends to get a bit smelly in the utility room when all the tent doors have been open.
Issue being, this time I set the ozone generator incorrectly and left it...
I wish I could say that were true, unfortunately not. The leaves apparently took more permanent damage than I thought. It's as if the whole garden was slowly strangled to death.
I know this is an old thread, but here's an example of what an ozone generator can do.
It was left running for approximately 4 hours in the room my tents were in, not even in the tents.
