Awesome. These are oysters grown in 100% coffee grounds. It doesn't take much.

Wow! I need to do more research. I have plenty of leftover coffee grounds. Iām also building an all new vegetable garden with (hopefully) a new greenhouse!
You can buy an oyster from the store. Slice it lengthwise down the stem. Throw it at the bottom of a jar and cover it with coffee grounds. It will grow and just add more grounds when needed. I am working on transferring it to a larger growing medium.
