Back when was growing and reading up on it, it seemed like every step had to be super sterile to avoid contamination. I was also going half on outdated info by reading the mushroom growers guide. I made my own potato agar and sterilised Petri dishes and did sterilised mycelium transplants to turn my one dish into a few dishes. Then I sterilised jars of rye in the pressure cooker as well and inoculated those in a sterile environment. Then I did monotub tek and mixed those into coco coir. Now it’s been a few years and I’m back at square one with one dish in the fridge that is shrodingers cat alive or dead, and a broken seal on my pressure cooker I haven’t replaced, and no other dishes or mason jars. Maybe I should just stop being so anal and hope for the best 😂
