Comment on Mushroom growing scale down minimal volume

I’m not a grower myself but fungi need oxygen and produce CO2 iirc. So if you put them into glass jars with small openings on top, it might just saturate with CO2, which of course then kills the fungus. Just spitballing though.

These are open jars, these particular ones reside in a plastic box with some water for humidity. I’ve tried different ventilation modes, from just leaving jars open in ambient to capping them with foil, still about same results (except when it dries out it stops growing sooner, of course)

yeah sure but the breathable surface area of the jar is miniscule in comparison to its volume also CO2 is heavier than air so every pore in that mycelium block is full of CO2 and it can’t go anywhere

Now that you mention it, I realized I just know the rate of diffusion of gas through plastic is enormous; I’ve done something really wrong trying to grow in vertically aligned jars!
