Pasteurizing manure? (lemmy.world)

I have chickens, who create quite a bit of poop I can use to grow mushrooms, but I'm not sure how to pasteurize/sanitize it. I was thinking pressure cooker?

I ordered some spore syringes and I'm not sure if i should get premade bags with injection ports or if I should make my own bags. It's the same cost to buy bags and a used instant pot, and I already have coco coir. Once I get some mushroom colonies going I was planning on keeping it going by breaking it up and mixing it with fresh substrate, but I don't want to keep buying pasteurized manure.

How do people do this? I'm very new

Cow manure is effectively slightly digested grass, and is pretty easy to sterilize. Chicken not so much. Jars are better because they can be reused, and the bags can occasionally melt if they touch the sides of the pressure cooker.

Also, different blends are required for gourmet than magic, generally either wood blends or maybe straw. Depends on the type, would recommend starting with oyster mushrooms.

No problem, hope it helps! If you want more tutorials, try checking out the shroomery message boards, bunch of knowledge over the decades (both for coir and gourmet). Happy growing!
