Anyone ever use CO2 to fight pests?!?

If anyone here has ever used CO2 to fight aphids or spider mites, can you please check me out here?

I need some help. I'm not 100% sure as to how to use CO2 to control pests but I'd like to "flood" a 4x4x7 tent with CO2 @ approx. 15,000 PPM to kill pests - I've read that only 1-2 hours under this 15,000 PPM CO2 will kill the first round off and to repeat every 3 days for about 3-5 treatments. Anyways, I don't have a PPM meter, just a tank and a simple flow regulator/guage like this:


It does .5-15 cfh. Can any tell me what I want to set my flow meter at to reach my 15,000 PPM for 1-2 hours. Any help will be greatly appreciated.

that flow meter isn't going to tell you anything, besides, if it isn't in a monitor to shut it on and off, it will just keep chugging away. If your dead set on trying it, just open your bottle for a few minutes , it's really hard to reach 10,000 ppm's, probably go and do it again every 45 minutes or so until satisfied.

Well, I know that this flow meter isn't going reveal the PPMs but I also know that to get to 15,000 ppm, all I need to do is get the CO2 to 1.5% as it is naturally occurring on earth at 400 PPM, or approx. .04%. A 4x4x7 foot tent is 112 cu ft. Now to get that 112 cu ft tent filled to 1.5%, I would probably need only 1.68 cubic ft of CO2.

Now I realize that the tent isn't going to be 100% airtight but I hope it'll be tight enough to store long enough before it slips out so I'm thinking I should set my regulator at 5 cubic Ft and run for an hour. Of course, my hopes are that after 6 hours of being shut off, it will be safe to open the tent - by then, I'm assuming the majority of the CO2 will have seeped out.

Can anyone see any flaw of logic with my plan? Am I overly optimistic or should I go higher than 5 cubic ft?

Thanks again.

Ive used co2 to suffocate mites on living blooming plants. I put my plant in a large trash can and covered the can w a trash bag. I dropped a block of dry ice in the can an let it inflate. Once inflated i put a few pencil sized holes in the bag to allow escape of the co2. Also because i thought it might pop. Left it for four hours. I did this w a hole row of plants three times one week. It stalled mite devel long enough to get my harvest. The population was developing fast too. I found it to be quite successful in this application. Would deff do it again.
