Growing your own mushrooms can be an exciting and rewarding experience, but what if you could also utilize your coffee grounds as the substrate? This sustainable and eco-friendly technique is gaining popularity among mushroom enthusiasts and coffee lovers alike. In this article, we'll guide you through the process of creating a thriving mushroom farm in coffee grounds and teach you how to transform your kitchen waste into delicious, nutrient-rich mushrooms.
Why Coffee Grounds Make a Great Substrate
-
Rich in nutrients:
Coffee grounds are packed with nitrogen, calcium, potassium, and other trace minerals that promote healthy mycelium growth
-
Sustainable:
Using coffee grounds as a substrate is an excellent way to repurpose and upcycle waste from your daily coffee habit
-
Low-cost:
Rather than buying expensive substrate materials, you can use something that you'd otherwise discard
Preparing Coffee Grounds for Mushroom Cultivation
-
Collect coffee grounds:
Save your used coffee grounds, or ask a local coffee shop to save theirs for you. Be sure to store them in a sealed container to prevent mould growth.

-
Pasteurize the grounds:
To kill off any potential competitors and contaminants, pasteurize your coffee grounds by heating them at 140°F (60°C) for about an hour. Spread the grounds out on a baking sheet to achieve even and thorough heating.
-
Cool and mix with spawn:
Once the grounds have cooled to room temperature, mix them with your mushroom spawn in a sterile container, making sure the spawn is evenly distributed. White button mushrooms, oyster mushrooms, and shiitake mushrooms are good choices for growing in coffee grounds.
-
Incubate:
Store your container in a dark, warm area and maintain a consistent temperature of 75°F (24°C). Regularly check on your mushrooms to ensure that the environment remains moist and free of contaminants.
-
Fruit and harvest:
After 2-4 weeks, the mycelium will have fully colonized the coffee grounds, and you should see your mushrooms beginning to fruit. Move the container to a cooler, well-lit area and mist with water daily. Harvest the mushrooms when they reach their desired size.
Crumbling Mushroom Farm In Coffee Grounds Example:
Jane is a coffee enthusiast who consumes several cups a day, producing a significant amount of coffee grounds. Instead of discarding them, she decides to grow oyster mushrooms using the coffee grounds as a substrate. She collects the grounds for a week and then pasteurizes them in the oven. Once cooled, she combines the grounds with oyster mushroom spawn in a large plastic container.
Over the next three weeks, Jane carefully monitors her mushroom farm, maintaining a warm, moist environment for her oyster mushrooms to grow. When she notices pinning, she moves the container to a cooler, well-lit area and increases her misting routine. In just a few days, she harvests her first flush of fresh, flavorful oyster mushrooms.
Jane is thrilled with how her mushroom farm has turned out and decides to continue growing mushrooms in coffee grounds, making her coffee habit more sustainable and reaping the benefits of home-grown mushrooms.
With some patience, care, and a bit of creativity, you can transform your used coffee grounds into a thriving mushroom farm, saving money and reducing your waste in the process.
