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 and humidity doesn't matter if the thing can't breath
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.
in that regard every text editor or any software that just CRUDs files locally would be local-first and the term would be meaningless
local-first means that it does not need internet-access to work and use the app and synchronization comes later, when there's time and internet access. please read up on this.
edit: i originally wrote "local-first means that it does need internet-access to work and use the app...", which is bullshit and also doesn't make sense in the context. i added the "not" so it is clear.
