Hey All,
Anyone using AirROS generators in their grow rooms? Looking for insight on how effective they are at reducing mold growth as well as whether or not they have a large impact on terpene content or quality of the final flower.
Thanks,

O3 is ozone
H202 is peroxide

Not sure if you read my whole post, but I stated O3 reacts with humidity to form H2O2. Which is what theoretically prevents the growth of mold.
There is certainly published work that suggests ozone can produce hydrogen peroxide in water droplets.

However, that is not the generally accepted model for it’s antimicrobial activity.
The Use of Ozone Technology to Control Microorganism Growth, Enhance Food Safety and Extend Shelf Life: A Promising Food Decontamination Technology - PMC
Compared to other oxidising agents, e.g., hydrogen peroxide (1.78 V), chlorine gas (1.36 V), and oxygen (1.23 V), ozone has the potential to react with other substances due to its high oxidising potential (2.07 V; Table 2), e.g., pesticide residue in grain products [22], toxic and micropollutants in waste water [25]. Ozone can also inactivate microorganisms such as fungus [26] and yeasts [27]; pathogenic bacteria such as Escherichia coli , Salmonella typhimurium , and Listeria monocytogenes [28,29]; and viruses and protozoa [30]. The inactivation mechanisms of ozone against microorganisms have been previously discussed, including the ozone penetration of the cells, attacking cell membrane constituents, inactivation of the enzymes, and degradation of the genetic materials of gDNA and total RNA. These activities eventually lead to the leakage of cellular contents and cell lysis [2,29,31].
Can you cite your source(s) please?

This is just what the manufacturer of the O3 generators told me. Happy to hear more about how that really works. But regardless of the mechanism of prevention, I am curious of how effective it has been for others as well as the effect on the product including terpene content and overall plant vigor.
While I agree that the mode of action doesn’t affect your primary questions (does it work? Will it affect product quality?), if your equipment manufacturer doesn’t understand the mode of action (is feeding you horse manure), I’d look elsewhere.

The best way to not have mold and mildew is to create an unfavorable environment for them, not to treat them with anything.
I like ozone to disinfect empty rooms, but it is generally considered at least unwise to use around people. I did once live in a small town whose city hall office where I paid my water bill had a gigantic ozone generator on the ceiling above where the employees worked. It bothered me just being in there. They seemed used to it.
If it’s probably bad for people, it doesnt seem that much of a stretch for it to be bad for plants, just a guess.

Care to out the vendor?
I’m receiving their claims second hand so take what has been passed along to me with a grain of salt. After reviewing their site, it seems like O3 is not what these units are actually generating:
They claim it generates ROS which has antimicrobial properties and also creates H2O3 for surface sanitization. I am probably incorrect in my initial statement of their claims.

Ozone makes rooms smell a certain way for months if you over use it
I definitely wouldn’t use this near any plants
My 2 cents

Yep. Which does change the question…
I was just about to point you at their website:
Impact on Plant Quality
High levels of ozone can negatively affect the terpenes, flavor profiles, and potencies of cannabis plants, diminishing the quality of the end product

Right, but they are actually stating why their solution is better because it does not use Ozone in the growth phase. So big misunderstanding on my part. I guess that changes the question to: Has anyone used AirROS systems before in an attempt to mitigate mold growth. The system seems to be two phase, a growth phase without O3 and a room sanitation phase that utilizes O3 while plants and people are not in the room.
And to further clarify, I’m not looking for it to kill pre-existing mold, I am hoping it will prevent or hinder growth from the start. We don’t have a large issue with mold, but a few select strains due to the nature of their bud structure struggle in our environment. I’m wondering if anyone has used their system with positive results.
Edited the title and original post to clarify.

I had a spot that converted a grow room into a lab space, before the retrofit they blasted the room with ozone for like a week and can confirm that ozone made the place smell like a hospital, the smell lingered for a while.
