Roses are red… Violets are Blue.
Mushrooms are lovely… And so are you.
Today I am super excited to share with you my latest adventures: growing yummy mushrooms in used coffee grounds and cardboard : so easily accessible by everyone!
This simple method requires no techy sterilization. And it can be done indoors and outdoors in any season! Below is a video of how fast they grew in just 4 days!
Ready to come down the rabbit hole with me?

Materials and tools:
- coffee grounds and cardboard: a match made in mushroom heaven. Coffee grounds are rich in nutrients, but can contaminate easily. Corrugated cardboard is not as rich and delicious to competing molds and bacteria, and the corrugation allows room for air and for the mycelium (mushroom roots) to run.
- mushroom spawn: think of them as mushroom seedlings. This beautiful box of Elm Oyster spawn ( Not all kits are spawn! See tips at the end!) came from 100th Monkey Mushroom , a wonderful family run business with many great products and tutorials. Eventually you can learn to grow your own mushroom spawn from mushroom stem base! But you do need great quality spawn to get started! (more on that at the end)
- clear plastic trash bags will come in handy throughout the process
- 70% to 99% rubbing alcohol to keep everything clean and reduce contamination
To start, ask for a bag of hot-off-the-press coffee grounds from the fabulous people at Starbucks, and soak some cardboard in water 1-2 days prior. The coffee grounds should be used on the same day, and the long soaking of the cardboard helps to hydrate the material. Continue to next page –
