Are you passionate about mushrooms and would like to grow them at home? With the innovative and sustainable method of cultivating mushroom plugs in coffee grounds, the possibilities are endless. Keep reading to discover the steps and benefits of this unique growing method, as well as some helpful examples to guide you in this process.
Why Use Coffee Grounds for Growing Mushroom Plugs?
Coffee grounds are an abundant and easily accessible resource in most households. They offer several benefits when used as a growth medium for mushrooms.
- Sustainable: Reusing coffee grounds from your morning brew prevents them from ending up in a landfill.
- Nutrient-rich: Coffee grounds are packed with various nutrients, which are essential for mushroom growth, such as nitrogen, potassium, and phosphorus.
- Anti-microbial properties: The compounds in coffee grounds can inhibit the growth of harmful bacteria, ensuring a healthier environment for your mushrooms.
- Water retention: Coffee grounds can hold on to a significant amount of water, creating a moist environment that mushrooms love.
Choosing the Right Mushroom Plugs
Not all mushroom species are suitable for growing in coffee grounds. Some of the most successful varieties include oyster mushrooms (Pleurotus ostreatus), shiitake mushrooms (Lentinula edodes), and lion's mane mushrooms (Hericium erinaceus). These species thrive in nitrogen-rich environments like coffee grounds and are easier to grow than other types of mushrooms.
Preparing the Coffee Grounds
Before planting your mushroom plugs in coffee grounds, follow these steps for the best results:
- Sterilize the coffee grounds: This is crucial to eliminate any potential bacteria or fungi that could compete with your mushrooms. You can sterilize coffee grounds by baking them in an oven at 300°F (150°C) for 45 minutes or steaming them for 45 minutes to 1 hour.
- Cool down the coffee grounds: After sterilization, wait for the coffee grounds to cool down to room temperature before introducing the mushroom plugs.
- Moisten the coffee grounds: Add just enough water to the cooled coffee grounds to achieve a moisture content of around 60-70%. The grounds should feel damp but not soaking wet.
Planting the Mushroom Plugs
Once your coffee grounds are prepared, follow these steps to get your mushroom plugs growing:

- Select a container: Find a shallow container with a lid, such as a plastic tote or a repurposed baking dish. This will provide a controlled environment for your mushrooms.
- Create layers: Spread a layer of coffee grounds on the bottom of the container, followed by a layer of mushroom plugs. Repeat the layers until you have used up all of your coffee grounds and mushroom plugs.
- Seal the container: Cover the container with a lid, leaving a slight gap for air exchange. This helps maintain a balanced humidity and carbon dioxide levels required for optimal mushroom growth.
- Incubate the mushrooms: Store the container in a dark place with a temperature between 60-75°F (15-24°C) to kick-start mushroom colonization. Check and mist your mushrooms every few days to ensure the container's conditions are maintained.
- Harvest your mushrooms: After 2-3 weeks, you should see small mushrooms beginning to grow. Harvest your mushrooms when they have reached their desired size and enjoy!
