bump no one know?
thanks for the help + rep
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
*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.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
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
= 1,224 cubic feet

wow that helps loads covered everything i needed to know thank you*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 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!
i'd rep you again for that but i have to spread it around firstGreat post..old but ever gold.*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.
