We start our oyster mushrooms in coffee grounds
As a departure from our on-site projects, I decided to take the Back to the Roots oyster mushroom growing kit home and get my twin teenage boys involved. The guys thought it sounded like fun, and also, the kit needs to be misted twice a day to keep the mushrooms happy, and I figured the weekend misting would be easier to handle this way.
The kit consists of the outer cardboard box, an inner bag of used Peet’s coffee grounds that have been innoculated with mycelium, brief instructions, and a small mister bottle.
