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!
I grew some oyster mushrooms in an all in one bag a few years ago and it worked perfectly. That sucks you poked yourself with the needle. I was so scared I was gonna do that. lol
That's good news. The mycelium in ours has started growing already. It's exciting to see.
How do you know if it's gotten contaminated? Is it when it's green or red, rather than white?
Pretty much any growth in there that isnt white during the first few weeks is contamination. After about 2 weeks, if you have a lot of white mycelium and you see some other color forming, there is a chance that the mycelium will actually kill the contaminated stuff.
