so therefore home ozone generators for grow purposes do not give off harmful gases

From the EPA website:

The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs (see - "Ozone and Your Health" - www.epa.gov/airnow/brochure.html). Relatively low amounts can cause chest pain, coughing, shortness of breath, and, throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. People vary widely in their susceptibility to ozone.

VUV Ozone generators, unlike Corona Discharge generators) do not produce harmful nitrogen by-products and also unlike Corona Discharge systems, VUV Ozone generators work extremely well in humid air environments. There is also not normally a need for expensive off-gas mechanisms, and no need for air driers or oxygen concentrators which require extra costs and maintenance.

Yes, and the EPA is saying that ozone - regardless of how its made - is harmful. In fact, "relatively low amounts can cause chest pain, coughing, shortness of breath, and, throat irritation"

Sorry kid, but I don't need wikipedia to school me on whether or not ozone is a gas. That fact is incontrovertible. Don't let the post count fool you. Nothing that I stated in my reply was incorrect. Not the part about ozone being a gas, not the part about it being very powerful odor remover and especially not the part about it being potentially hazardous.

While I'm sure consumer ozone generators have safeguards in place to protect the user from harm, because of the unstable nature of ozone, there is always the potential for risk. This is because of the way ozone goes about odor removal, by basically obliterating the smelly and unsmelly molecules indiscrinimately.

Now carbon, on the other hand, acts as a traditional filter. It takes smelly air and actually does absorb the smelly molecules into the carbon. There is no unstable reaction like there is with ozone. The downside to this is that eventually the carbon will wear out and need to be replace.

Both options are suitable for odor removal when done correctly. But it would be naive to ignore the risk of ozone when making your informed decision. That's just being foolish.

OZONE IS A GAS AS IT IS COMPOSED 100% OUT OF OXYGEN. WITHOUT ANY OTHER DIFFERENT ELEMENTS ATTACHED, OXYGEN IS OXYGEN AND THUS OZONE IS A GAS.

This is basic high school chemistry. Ozone is a free radical gas that can act as anything from a caustic to an air deodorizer.

That being said, I prefer a carbon filter and fan combo. I've seen ozone generators burn plants, even the home units in small closets.

I read about a grow using industrial ozone generators and there was a loss of potency in the buds but I like the idea of having one in whatever area of the house I entertain in to keep the smell down.

now thats just a crazy idea, lets buy a 6" fan, get a variable controller, turn down the speed so it sucks less air than a 4" fan,

Really can you show me figures where a 6 in fan at 90% pulls less than a 4 inch. lets do some math here since you appear to not have gone to school.

Can fan 4 inch 170 cfm
can fan 6 inch 440

the math..

440 * 90% = 396 cfm for a 6 inch fan @ 90% power if you consider linear power to cfm ratio which it is not but @ 90% power you are still generating more than twice the airflow so you have some cfm's to work with.

BUT WAIT!

CFM was not the point of my original post! Noise was! SO STFU! :hump:

Edit: I just realized that I forgot to spell out for your dumb ass that 396 CFM is MORE than 170 CFM. That means that turning it down 10%, the 6 inch will move about TWICE the air of a 4 inch at full steam. I hope that was clear enough for you to understand

HowardWCampbell · Apr 11, 2009

olosto, I'm in the process of trying to decide on a long term exhaust solution. How noisy is your can fan compared to a cpu fan? I'm using some cheap, noisy cpu fans right now. I'm trying to decide on a can fan, or if I should save up the money for a soler fan.

Are you using the speedster controller?

One problem with your math - that 10% reduction in power doesn't necessarily mean only a 10% decrease in airflow. In fact, due to friction and other forces in thermodynamics, using 10% less power is more likely to give you around 25-30% less airflow. Still faster than the other fan but you're dropping your efficiency by a fair load.

Hey all.
I need to do something about the skunk smell... Does anyone have an opinion about which way to go....
carbon filter vs. ozone generator. I would be using it in a 4" x 5" x 8" room. I currently have 2 plants that just started 12/12 under 400W HPS.
Thanks!

no question carbon filter hands down. i have a room similar size to yours wit 40 plants in it right now. no smell no noise. i use a profilter 75 wit a six inch vortex fan. cfm 640. check out the links

Hi guys,
Im starting a small grow room in a tent 1.4mt * 2.4 mt * 2.4mt, 4" clean air in , 5" outlet , 1 * 600 watt 1 * 400 watt hps lamps hydrow system virgin can carbon .
Now to the question, i saw this on uk ebay item no . 300306566225 im venting to a small walkway at the rear of the garden not sure if this will help on the smells.
kiss-ass :mrgreen:

skoooooot · Apr 14, 2009

Im going to post a picture of my exhaust fan tonight. Its an old kitchen wall exhaust fan. I think its going to do the trick... and I believe I can rig a carbon filter to it. Im passing on the Ozone Generator. I dont think its a good fit for my small room. Thanks to all who posted.
I havent been able to use the exhaust fan yet... our temps have not warmed up yet in New England. I have my vent port filled with insulation board. Another week or so and I can remove it.

nasd90 · May 4, 2009

Yeah, I can say that I'm returning the OZN-1 Ozone Generator I purchased last week.

I had it on for 20 minutes, off for about 60-90 and it almost fried every single plant I have at 8 weeks flowering.
The thing is scary and I don't even think it removes the smell as much as it covers it with another smell. It's not worth it.
My smell isn't that bad, I'm going to get some ONA gel and be done with it for a while...

Peace.

I cry every time I hear of a crop screwed by ozone. You have my major sympathies.

I've been wondering if those block sea salt air fresheners might work, if those aren't a scam to begin with.

yeah, it blows. Not totally gone, but just a lot of yellowing & burning. That stuff is nasty. I started feeling hoarse everytime I left the grow area...

I did harvest a couple top cola's, they were in between. sticky as all hell.

I can say that the Venus I have growing is a great high, all around great pot.

The Snow White on the other hand is deadly, couch-lock, goodnight... not for children.

I dont understand all the hype with people buying Ozone generators for Odor control....They are about as effective as a plug in glade air freshener.

If you want an odorless grow, buy a 4" flange carbon filter with at least 11lbs of carbon, buy a 4" can fan and a fan controller. Even if you only have 1-4 plants is worth it. You spend $300 on a fan filter combo, and a controller to keep the noise down from the fan, and you have a 100% ODORLESS grow. You can be standing in your grow room and you wont be able to smell the weed. You gotta rub your fingers on some bud to get a whiff of the chronic.

Its a pretty small investment considering the results. You dont even need to duct it anywhere, just have a carbon filter/fan sitting in the corner of the grow room.

I use 2 filters, 1 for exhaust and 1 for passive. I ALWAYS run a passive filter that just recirculates in the room. It will cut down odor like 300%. Your grow room will smell cleaner then the rest of the house...lol.

BTW, I buy carbon filters, good ones. They are easy to refill the carbon, but its worth investing in them at least once for the filter housing. They work better then ANY of that DIY crap.

You're totally right... and said very well. Rep to you my THC bretheren... I am actually thinking of just getting some high-end scentless strain seeds and going from there... eh ?

"...You gotta rub your fingers on some bud to get a whiff of the chronic...."

That's priceless.

Actually, they DO work. We use them after parties to kill the smoke smell and prevent that smell from being embedded into carpet and the paint and drapes. Ozone is a free radical that will break up most organic substances, and in itself has a strong odor as well that works as a cover-up while it destroys the organic molecules that make up a smell. It works in garages to keep the smell of oil and other mechanical fluids out. I have a 12v one that I plug into a new car to kill that new car smell and make it totally neutral.

They're just bad to use around living things. Used outside of the growing room, they are effective and create a scent neutralizing barrier between the plants in the closet and the hallway. Inside of the growing room, big mistake, as I taught one grower on here. He had like 4 or 5 in the grow room. Holy shit that was bad.

I didnt say they didnt work did I? I said they are not very effective for an average grow room.

I would bet they work great after parties and shit, if you got ttime to leave it running without worrying about it.

Only place I would use an Ozone Generator would be in room that everything was being exhausted to before going outside. Never in a grow room or a room with any plants or animals, or humans.

lol. I repped him too. Tipped me right over to the dark (carbon) side.
