Well I'm not sure to be honest, it's very hard to judge smell as it's subjective and I've had my head in chopped weed for 3 days lol.
I'm drying the trim from the bigger one on a Pyrex dish in the oven with the ozone on in the kitchen with the window open crack and a towel across the bottom of the door.
When I stick my head in I can't smell weed until I take a deep sniff and then it's only a very slight touch on the back end, by taking that deep sniff though I can feel the Ozone tingle in my hands and fingers so it's quite powerful stuff.
I think it most certainly works just not how most people realise, if I got one for myself (likely now) I'd have to work out the ideal situation for it.
I'm gonna show my helper how to make bubble later when he's finished work so I'll get a second opinion.
i have ozone running 15 mins every hour when the lights are on , when the lights are off it does not run as the smell is not such a problem then
i did read something about the half life of ozone being more unpredictable at lower temps, instead of the 20-30 min half life it could hang around for hours apparently when the lights are off temps are normally quite low
if i run it for 30 mins every hour i can smell ozone in every room in my house as i vent from room to room i can feel it in my eyes like a mild version of a public swimming pool with all that chlorine so 15 mins is all i can handle , i do not see any reason to put it directly inline with the filter or in the ducting as i cant smell anything coming out of my filter anyway, although when i was growing blues i could smell it a little bit
its the smell in the room and the smell that may leak out of open windows in other rooms of the house that it helps control, when i stand in my back garden i can only smell the occasional waft
of ozone come out in a waft of warm air lol
overall it works well to reduce the smell and is cheap for only £30-40 for 200-300 mg/h machine
how it works i only know the basics what i have read ozone will bond/react with other particles the new bonds it forms with the smell particles neutralizes them, sounds great lol
if run in the room with the plants i cant smell anything but ozone when the machine is on, i do notice a very slight bit of ozone damage on some leaves near the machine but nothing to worry about
i have looked into alternatives like hydroxyl generators, but they are very expensive not many reports out there not sure i want to take such a risk in it not working for all the money they cost
the bonus with hydroxyl generators would be unlike ozone you could run hydroxyl all the time with no worry about poisoning yourself lol
