ozone while drying?

[ginjawarrior]

im waiting on delivery of a ozone generator http://www.hg-hydroponics.co.uk/mountain-breeze-ozone-generator-217-p.asp
would it be good idea to use ozone during drying to let me have a slower dry without risking mold?

bump no one know?
the reason im asking is because of ozone's oxidizing properties im thinking it possibly could damage the thc similar to heat or light.

im just about to start to harvest my plants. now i was planing to dry them under a false bottom in my cabinet

i got 3m filter in floor of cabinet, i then have a false floor with holes in and clothe over that my plant sits on. now this void under the false floor would be perfect to dry i think

my intentions tho was to put the ozone under the cabinet floor (before the 3m filter) so the ozone would be straight onto the drying herbs

I have a 600mg/hr corona discharge ozone generator. I ran it two minutes per hour, meaning 20mg and it had no detrimental effect to the bud. The thing you want to keep in mind is that the ozone generator shouldn't be too close to you hanging buds. You also will need a circulation fan to help move the ozone to kill any potential mold spores in the air.

I didn't read your second post, I wouldn't put the ozone generator right below the herbs, it might oxide your terponoids and take away the taste and smell.

thanks for the help + rep

the cabinet had got pretty good airflow its switches between about 167.745cfm and 359.034cfm so the ozone wouldnt have time to linger at all do you think that would matter?

i might just put the ozone generator inside the cab above the false floor and hope that the filter does it's job well enough

Watch the length of time its on if you have pets or small children around, I am pretty sure the ozone can make you sick with sore throat if you have weak immune system this could be issue

If you have good airflow it may not be an issue. One way to test this is by observing the smell of the ozone. If it smells extremely potent, then it's too concentrated, but if you only smell it slightly, then it's the perfect amount. The later means that you are using just enough ozone to destroy excessive cannabis odor and airborne particles such as mold spores.

I wish I could be more informative, but ozone usage isn't very clear cut and requires some physics conversions to determine the exact amount. There is a certain ppm of ozone you can maintain that will be effective for your purposes, but won't pose any health risks, even if exposed to it for an extended period of time.

What are the dimensions of the area that will be treated with the ozone? We will need to calculate the cubic volume to determine ppm.

Also, how long will you run your generator? 80 milligrams an hour is way too much for a small area. Once we determine your cubic footage I can tell you the appropriate time to run it.

lol well i hadnt gotten around to working out the amount i needed was just working on the theory of placement while i waited for it to arrive but if you willing to help i'll bend your ear on this
the generator im getting says its adjustable down to 10% so 8 milligrams an hour i think thats constant flow

the flower box is
3'x2'x5,6'
but more importantly the intake and exhaust go into my bedroom which is
17'x9'x8'
now theres normally pretty good airflow around the house even with doors shut there is still some air exhange but i recon i need to work out for the larger room as the air in the flower box is changed between 5-10 times a minute

yeah i will be careful i bought pretty much the smallest ozone generator i could find gonna get it all worked out before its switched on

*If you want to know a straight answer, then skip to the bottom, but if you want to know how I came to it, continue below.

Ok, first, let's tackle some of these conversions.

[FONT=Century Gothic, Arial, Helvetica]Volume of Drying Area:[/FONT]

[FONT=Century Gothic, Arial, Helvetica](3)(2)(5.5) = 33 cubic feet[/FONT]

1 cubic foot = 0.0283168466 cubic meters

(33 cubic feet)(.0283) = 0.9339 cubic meters

Volume of Room:

(17)(9)( = 1,224 cubic feet


1 cubic foot = 0.0283168466 cubic meters


(1,224 cubic feet)(.0283) = 34.63 cubic meters

Now that we have established cubic volumes we can decide how much ozone is needed using this very useful conversion.

1 PPM O3 = 2.14 mg O3/m3


The FDA recommended of to ozone is .05 parts per million. However, welders are often exposed to levels as high as .1-.2 ppm for several years without adverse health effects. The choice is yours. We can divide the left and right side of the above equation with which ever ppm level you are comfortable with. I will calculate ozone needed for .05ppm, but if you want to go all pout just multiply my final answer by to to get ozone needed to reach .1ppm.


(1 PPM O3)/20 = (2.14 mg O3/m3)/20


.005 PPM O3 = .107 mg O3/m3


Excuse the weird formatting, but RIP is being weird. Basically, you will need .107 milligrams of ozone for every cubic meter of space you have to achieve the .05 PPM we had mentioned. Lets calculate how many milligrams that is. Back to the volumes we calculated at first.

To achieve .05 PPM in Drying Area:

(0.9339 cubic meters)(.107 milligrams of ozone)= 0.0999mg of ozone. At 80mg/hr, this could be achieved in approxiamately 5 seconds.


To achieve .005 PPM throughout entire room (assuming your air flow is good as you say it is, )

(34.63 cubic meters)(.107 milligrams of ozone) = 3.7 mg of ozone. At 80 mg/hr, this could be achieved in approxiamately five minutes.


After all of that mess, we can finally say how long you should run your ozone generator. 5 minutes per hour at 80mg/hr, 10 minutes per hour at 40mg/hr, 50 mnutes an hour at 8mg/hr, or at 10% and so on.

Rememeber, if you want to go Macho Man on the mold and reach .1 PPM of ozone, then just multiply the three figures in the paragraph above by 2. 10 minutes per hour at 80 mg/hr, 20 minutes per hour at 40mg/hr, and so on.


I, personally, would run the ozone generator at 50% for 10 minutes every hour. Ozone has a half life of 20-30 minutes. This would ensure too much isn't being built up in your room.

One last thing that I would feel bad if I didn't mention. Ozone only kills what it comes in contact with. Like I said I have a 600 mg/hr ozone generator and I still got mold inside some of my thickest colas. You can prevent this by keeping your growing and drying areas as clean as possible unlike me, lol. The ozone generator will do the rest of the ass kicking. Hope this helps!

wow that helps loads covered everything i needed to know thank you i'd rep you again for that but i have to spread it around first
yeah im gonna be real careful about mold this is my first harvest and i wanna smoke it lol. first thing im gonna do when i get the ozone generator is give my room/ grow box a full dose of ozone for a few hours to try and sterilise everything as much as i can before i even start on the cutting and drying hopefully that should be enough.
thanks again for the help tho will rep as soon as i can

Great post!

Very helpful info. I just bought a cheap 25$ 10"x10"x3" plastic generator from china that claims to be 600 mg/hr. Would you guess that claim is accurate? I didn't do my homework on the downside of ozone and am hoping it is more like 60/hr as I have a grow closet in a small apartment and don't want to worry about ventilating that much ozone.

Would appreciate any insight. Thanks again for the quality post
