Shrooms have to be grown in sterile substrate. It requires more than just boiling some wheat berries, you need a reverse hepa filter blowing clean air on your workplace when you inoculate. It’s a ton of work but you can growing a staggering amount of shrooms if you follow protocol and sanitize everything. If you don’t sanitize you will never grow a single shroom. They are hopelessly fragile.
I tell people that are interested that's it's not hard so long as you follow the 3 cardinal rules. Watch your temp, humidity and airflow. Yes, being sterile is important, but only until the substrate has been totally seeded. By the time you take the cakes out of the jar to give them a water bath they are fairly resilient. The fungus has it's own immune system. Granted, you still can't be exceptionally dirty, you just don't need to be extra sterile.
