Hydroxyl for odor control

[High Grade Only]

sometimes, even with tons of negative pressure and the largest carbon filters available, i odor control an issue. so when i hear of a new product, i am automatically going to be interested.

We all know ozone generators can't be placed directly in rooms, not only because ozone is harmful for us to breath while in the rooms, but also because it will pull the smell right out of the product.

So do a search for "hydroxyl" generators and let me know what you think. Their studies are claiming it's safe to breath, yet they are producing hydroxyl radicals with a UV lamp.... sound familiar?

anyone have knowledge of these generators? used them? how do they differ from ozone gens? are they going to effect the final products smell? are they really safe to breath?

I don't know nothing yet about these hydroxyl generators.

You could keep incense sticks and scented candles nearby.

They help in the plant odor disguising if not used in excess.

its called POC. photo catalytic oxydation.

its been around for a long time... recently its been sold as a drop in ducted air purifier, reviews are mixed. the principal is sound, but ramping it up huge scales costs ALOT of money owing to the large amounts of noble metal catalyst.

u basically take a strong uvc source and blast light onto a catalyst on titanium lathe, or better... a paladium on carbon monolith. both are expensive.

i talked about this a while back in regards to ethylene oxidation. back then they were still like 700 bucks for a rather small in duct unit... idk what they are now.

POC producers require a heating element, usually a burner, and is used in surf board manufacturing to cure rosin. and "in regards to ethylene oxidation"? And, ethylene oxide is a colorless flammable gas... please inform us about what you are talking about and provide references

corky, i am referring to odor control for large set ups, for a reference, check my photo gallery for small examples of portions of gardens.

I guess that would be expensive buying candles for all of that jungle you have.

I'm so used to seeing grow tents or cabinet grows.

odoroxhg.com one of the many companies pushing it

it requires no heating elemement.

you are probably confusing uv cured or uv cross linked resins and polymers.

can also be called photolysis .. contraction of photo+catalyst

basically uv curing polymers or resins involves polymerization.

what im talking about is the generation of hydroxyl radicals that can oxidize many organic compound.

regarding proof... i suggest you just google it.

you can probably search for POC or photocatalytic here on ICmag to find the thread im talking about.

it was maby a year ago? maby more idk.


idk anything about surf boards or wtf rosin is, but i was taught way back how to fabricate airplane parts with foam and multi layup fiberglass... i imagine its quite similar. no uv light was required... only heat and pressure so im not quite sure what you are referring to.

referring to ethylene oxide... oxidation does not mean X chemical + oxygen.

in organic chemistry it jsut referrs to the loss of electrons by something.

now... ethylene oxide might be an intermediate... but it will be a short lived intermediate.

google radical addition to alkenes. or oxidative cleavage of alkenes.

the double bond of ethylene will be the reaction site here. pi bonds are far more reactive than a sigma bond owing to how the electron cloud sort of wanders off into space.

now its not always the case... like with benzene those pi bonds are fairly stable and unreactive... but thats due to very cool phenomina called ring stabilization or ring resonance.

anyway what ever. i dont think anyone here cares about this shit.
