As a mushroom enthusiast, you've probably already heard about the amazing health benefits of mushroom coffee and mushroom gummies. But what if we told you that you could grow your own mushrooms from used coffee grounds, right in your own kitchen? That's right! In this ultimate guide by Mr. Mushroom, we will teach you how to transform your morning coffee ritual into a sustainable and nutritious passion project.
Harnessing the power and nutrients from used coffee grounds, you can grow vitamin-rich mushrooms at home, reducing waste and saving money. So, let's delve into the fascinating details of growing your own mushrooms from coffee grounds.
Why Coffee Grounds?
Coffee grounds make an excellent substrate for growing mushrooms as they are rich in essential nutrients like nitrogen and phosphorus. These valuable substances promote faster and more abundant mushroom growth compared to traditional cultivation methods. Going beyond its nutritional benefits, growing mushrooms in coffee grounds contributes to waste minimization, making this a truly eco-friendly gardening hack.
Preparing the Grounds
Though it may sound complicated, getting started with growing mushrooms in coffee grounds is surprisingly simple. Follow these steps:
1. Collect and store used coffee grounds
Keep a container next to your coffee maker and collect the grounds after each cup you brew. You can also ask local coffee shops for their used grounds, which they usually discard anyway.

2. Sterilize the coffee grounds
To protect your mushrooms from contaminants, pasteurize your coffee grounds in a pot of boiling water for 30 minutes or bake them in an oven at 180°F (82°C) for 2 hours.
3. Choose the right mushroom variety
For beginners, oyster mushrooms are the best choice as they have a high tolerance for pH levels and are less demanding when it comes to nutrients. Experiment with other types once you've mastered the basics.
4. Buy mushroom spawn
This is the vegetative growth of the fungus, which you can easily find online or at a gardening supply store. It comes in the form of sawdust spawn, grain spawn, or plug spawn.
Growing the Mushrooms
Once you have your prepared coffee grounds and mushroom spawn, follow these simple steps:
1. In a clean container, mix together the sterilized coffee grounds and mushroom spawn. The ideal ratio is 5 parts coffee grounds to 1 part spawn, but you can adjust depending on the amount of spawn you have.
2. Make sure the mixture is well-aerated and evenly distributed. The key is to ensure that the coffee grounds aren't packed too tightly and provide enough air and space for mushrooms to grow.
3. Cover the container with a breathable lid or plastic wrap, allowing oxygen to flow freely.
4. Store the container in a dark, humidity-controlled area with a consistent temperature of around 65-75°F (18-24°C). This could be a cupboard, basement, or a cardboard box.
5. Periodically check on the progress of your mushrooms. They should start to grow within two weeks. If you notice any unwanted mold, remove it immediately with a spoon or fork.
6. Harvest your mushrooms when the cap opens and begins to "flatten," which usually happens every 3 to 4 weeks. Don't wait too long, as overripe mushrooms may not be as flavorful.
Congratulations! You've now learned the steps to cultivate your very own mushrooms in coffee grounds – a sustainable and eco-friendly approach to mushroom production. Not only have you gained a practical and cost-effective way to grow your mushrooms, but your newly grown batch will taste even more delightful in your mushroom coffee and gummies.
