Pretty sure those are just bought like that, and they’re compostable bags as well.
No, I make these up myself and they are not compostable.
Ah well that’s cool either way. I just know there’s kits online and in some stores you can buy.
Mean like the bags come as a kit with the grow media already inoculated?
I've not yet seen that compostable plastics are actually safe for the environment yet, although they might be slightly better since they can break down given the correct environment (not naturally, unless bio-degradable). I suspect anything with a co-polymer to be dangerous in various ways.
This article seems to indicate so atleast, but I would like to see more studies.

As far as I understand.
And maybe used the wrong term, but yes, some breakdown as biodegradable as well.
