    I've already been to this site. They only listed places like Praxair and Linde, who supply the big cylinders.

    That's quite plausible!

    There's this too! Still on the expensive side but lasts 60-90 days depending on use.

    You could always put them in a metal rash can with lid and put a lit candle or alcohol lamp. Put the cover on, the flame will consume the oxygen and so on. No light to process the CO2. Place the flame source higher than the plants.
    Grand Hotel... always the same. People come, people go. Nothing ever happens.

    I really liked this idea as well and googled it a bit a while back. I ended up finding a couple sources though (dont know how reliable ) that claimed that the oxygen would be consumed until it could no longer sustain a flame but that the residual oxygen levels would be sufficient enough to sustain small critters. i.e. springtails etc... I'll see if I can find the source, it's been a while.

    Maybe using the candle + yeast jar would work pretty well?

    This does look like it would work.

    On the CO2 boost system, it doesn't produce CO2 fast enough to kill bugs. I have two of the systems.

    Using flame or car exhaust; are we confussing carbon dioxide (CO2) with carbin monoxide (CO)? Would they work the same for killing bugs; but OK for the plants?

    Ive not studied this in many moons but as long as the air/fuel mixture is above stoichiometric then CO2 is produced and not CO... (at least in theory) But burning something until the flame goes out would definitely not meet that criteria
    (Warren's example is safely isolated in a bag or box of course...but I can see the lightbulbs going off, for our younger membership... leave the exhaust pipe alone LMAO)
    They do sell CO2 generators that burn propane (Lean burn with 10-20% excess oxygen) for greenhouse use, but they are generating supplemental levels, not trying to fumigate.

    But CO might do just great too, Wal-Mart treats their meat with it to kill everything... just don't kill yourself in the process

    CO2 good, CO badddddddd.... but in high enough levels both are deadly LOL

    The hobbyist called Indiana Grower also suggested that. I'm not sure how to control that set up. I was wondering if the flame goes out too soon.

    A co-worker suggested ****'s Sporting Goods, in their gun shop, as one who would stock the CO2 kit. I went to ****'s, but they did not have what I was looking for. Spying a place called Bert's, along the way I went to them and they did have a CO2 kit.



    Oddly enough, I don't have aphids at the moment, but I'm sure they will re-emerge as it warms up and trades get going again.
