There seems to be differing opions on the level of co2 necessary to kill bugs. Co2 WILL kill all bugs as it is toxic, its not just the fact that oxygen levels are reduced. Grain is stored in super high co2 levels...like 70% co2 which is 700,000 PPM. There are several journal articles out there about co2 concentrations and exposure times to kill various pests. The most usefull article however has units that I can't fucking seem to convert
10,000 ppm is the number I have heard thrown around quite a bit. Some people swear by it. My monitor only reads to 5k. I have gased spider mites before and had mixed success. Again, my rates might not have been high enough. Spider mites and aphids don'[t need a whole lot of co2 to kill them. Fungus knats however need dangerous levels.. Levels that I would not want in my basement...like 100,000 ppm.
in terms of bottled over burner... I HIGHLY recommend you get a burner. A tank only lasts a week at best in a small sealed room and runnning back and fortha nd back and forth to get bottles is a REAL pain in the ass. This is not to mention that bottled co2 is 600% more expensive than propane, or even better NG generated co2. Check out my tankless water heater thread,,,
very true 10,000 PPM is what I was told will kill all pests in your sealed environment.
