My first el cheapo attempt at growing shrooms is looking up. Those are King Blue Oyster mushrooms that are beginning to form “knobs,” which will generate mature shrooms. These have only been in the jar for a few weeks, and we should have good shrooms by next month.
Now to explain the el cheapo part. I have had the Paul Stamets more or less bible on growing mushrooms for years, but it breezes past the easy to grow part, and is geared more toward the pro grower, which I am not. Then I ran across an article by fellow Southerner Tradd Cotter about growing Oyster shrooms on used coffee grounds. It works like a charm.
The process is this: layer used coffee grounds with the filters, and then add some mushroom spawn–I bought mine on fleabay, and they were top quality and dirt cheap. Repeat this until you reach about an inch from the top of your container. As Cotter rightly points out, this is the perfect way to recycle kitchen waste.
We should get more shrooms than we can eat here, so we will have to learn mushroom preserving methods next. I bet they will can well.
