My daughter recently bought a couple of grow bags of mushrooms, so when I saw your thumbnail I recognised them straight away. I might have guessed yours would be the magic kind, though. 😆 Ours are enoki and oyster. Fingers crossed we don't get contamination. My daughter asked me to join her in preparing them and clumsy me stabbed myself with the needle. Luckily I didn't have my hand on the plunger...

I would never have guessed growing mushrooms would be so intricate. So much sterilising needed for a fungus!
