So it's looking like a company, CO2 Boost , is selling spawn buckets as CO2 generators. They claim to last 60-90 days, and they charge around $100 each. I've seen these buckets before; they're maybe about 2 gallons, and the sort of thing you could keep out of sight. Perhaps it would be possible to simply buy some spores and start a culture of your own, rather than paying a ridiculous price. From there it would just be a matter of performing partial substrate changes. To prevent the mycelium from running out of O2, a trickle of air could be run in through a pump at the top, while the CO2 siphons through a hole towards the bottom.
My hope would be that it could provide more stable CO2 than pure DIY, though perhaps not so much of it per cm3 of culture. The other part would be that rather than buying yeast and just throwing the culture away (unless you really like making bread) that the old mycelium changed out could be used for garden soil, or brought out of stasis to fruit.
The whole thing is pretty rough in my mind, but I thought it wouldn't hurt to post the concept, and see what other people think.
