How do you prepare the coffee grounds to grow oyster mushrooms?

Hello, and thank you for your comment!
I have been working at growing mushrooms on coffee grounds without any preparation. If you can get them started before they mold, your chances of success are much greater. Storing the grounds outside in the winter keeps the mold down.
There are many options available including pasteurization and sterilization. These options are expensive and labor intensive. I have had the greatest success with mixing fresh coffee grounds and oyster spawn in burlap bags. Moisture content is tricky and the burlap wicks moisture where needed. Oyster mushrooms will out compete mold, but it slows the flush. Good luck and let us know how you do,
Dean
