What Are the Best Practices for Cultivating a Mushroom Garden Indoors?

March 11, 2024

Mushrooms are a fascinating form of life. Neither plant nor animal, they belong to a kingdom all their own, and their cultivation can be incredibly rewarding. The process of growing mushrooms involves several stages, each with its own set of requirements and challenges. This guide will provide you with the best practices on how to grow mushrooms indoors. Whether you’re a beginner or a seasoned grower, you’ll find useful information about the appropriate substrate, humidity and temperature conditions, the best species to grow, and much more.

1. Choose the Right Mushroom Species

Before you dive headfirst into the world of mushroom cultivation, you need to figure out what type of mushroom you want to grow. The choice of species is crucial because different mushrooms require different growing conditions.

Oyster mushrooms are a popular choice for indoor cultivation because they’re relatively easy to grow and have a fast fruiting cycle. These mushrooms thrive on a variety of substrates, making them a versatile option for beginners. They’re also delicious and packed with nutritional benefits.

Shiitake mushrooms are another good choice. They take a bit longer to fruit than oyster mushrooms but have a rich, savory flavor that many people find irresistible. However, they require specific substrates, such as hardwood sawdust or logs.

The type of mushroom you choose will dictate the subsequent steps in the cultivation process, including the type of substrate and spawn you use, as well as the temperature and humidity conditions you’ll need to maintain.

2. Prepare the Substrate

The next step in mushroom cultivation is preparing the substrate. The substrate is essentially the medium that the mushroom mycelium, the fungus’s root system, grows in. Different species prefer different substrates, but some common options include straw, wood chips, and sawdust.

For oyster mushrooms, a substrate of straw or coffee grounds can be used. Sawdust is the preferred substrate for shiitake mushrooms. Before the substrate can be used, it needs to be pasteurized or sterilized to kill off any potential competitors for the mushrooms.

The substrate should be packed into bags or containers, which are then inoculated with the mushroom spawn. The spawn is the mycelium of the mushroom, which will grow and colonize the substrate.

3. Maintain Optimal Growing Conditions

After the spawn is introduced, the bags or containers should be moved to a location where the temperature and humidity can be controlled. The mycelium needs to develop and fully colonize the substrate before fruiting can occur.

Mushrooms require specific temperature and humidity conditions to thrive. Oyster mushrooms, for example, prefer a temperature between 55 and 75 degrees Fahrenheit and a humidity level of around 70-80%. Shiitake mushrooms prefer slightly lower temperatures and similar humidity levels.

It’s important to keep an eye on these conditions and adjust them as necessary. Failure to maintain the right conditions can hinder the growth of your mushrooms or even lead to contamination.

4. Initiate Fruiting

Once the mycelium has fully colonized the substrate, it’s time to initiate fruiting. This involves changing the conditions to signal to the mycelium that it’s time to produce mushrooms.

The temperature needs to be lowered slightly, and the humidity increased. Fresh air is also important, as it triggers the mushrooms to start fruiting. The bags or containers should be opened or punctured to allow for air exchange.

During the fruiting stage, it’s crucial to maintain the right conditions. The substrate should not be allowed to dry out, and the temperature and humidity should remain steady.

5. Harvest and Enjoy!

Once the mushrooms have fully developed, they’re ready to be harvested and enjoyed! The best time to harvest is just before the caps fully open up.

Growing mushrooms indoors can be a fun and rewarding experience. With the right species, substrate, and conditions, you can cultivate your very own mushroom garden right in your home. But remember, patience is key. It could take several weeks for the mycelium to fully colonize the substrate and for the mushrooms to fruit. But the wait is definitely worth it when you get to enjoy your very own, home-grown mushrooms.

6. Enhancing Your Mushroom Garden with Variety

If you’ve successfully cultivated a batch or two of mushrooms, you might want to consider expanding your indoor mushroom garden with a variety of species. This can provide a unique aesthetic, as well as offer a diversity of flavors and textures for your culinary explorations.

Lion’s mane mushrooms are a great addition to consider. They have a unique appearance, resembling a white waterfall of icicles, and a flavor often compared to seafood. Lion’s mane mushrooms prefer hardwood substrates and require a higher humidity level, around 80-90%. It’s also essential to provide them with plenty of fresh air.

Maitake, or Hen of the Woods, is another excellent choice for indoor cultivation. These mushrooms grow in large clusters with a flavor profile that is rich, earthy, and slightly spicy. They thrive on a substrate of hardwood sawdust or chips, and like shiitake mushrooms, they prefer slightly cooler temperatures, between 50 and 60 degrees Fahrenheit.

For a truly eye-catching addition, consider growing bioluminescent mushrooms. These species, such as the Panellus stipticus, glow in the dark creating a captivating sight in your indoor garden. They prefer decaying wood as a substrate and thrive in cooler temperatures, between 60 and 70 degrees Fahrenheit.

Remember, adding variety to your mushroom garden also means accommodating different temperature, humidity, and substrate requirements. Be prepared to segment your growing space or adjust your routine to provide the best conditions for each species.

7. Troubleshooting Common Mushroom Growing Problems

Cultivating mushrooms indoors isn’t without its challenges. However, with some awareness of common problems and their solutions, you can ensure your mushroom garden thrives.

One common issue is contamination. If other organisms start growing in your substrate, they can take over and prevent your mushrooms from colonizing. This problem can be avoided by properly sterilizing or pasteurizing your substrate before introducing the mushroom spawn. If contamination occurs, it’s best to discard the affected substrate and start fresh.

If your mushrooms aren’t fruiting, it might be due to incorrect conditions. Double-check that you’re maintaining the right temperature and humidity levels for your specific mushroom species. Remember, initiating fruiting often requires a change in conditions, such as lowering the temperature or increasing fresh air exchange.

Lastly, if your mushrooms seem to be growing slowly or not at all, it might be due to poor-quality spawn. Always obtain mushroom spawn from reputable sources to ensure it’s viable and healthy.


Mushroom cultivation can be an engaging hobby or a means of growing your own nutritious food supply right at home. Be it oyster mushrooms, lion’s mane, shiitake mushrooms, or any other type of fungi, each species has its unique requirements for the best growth.

The key to a successful indoor mushroom garden is understanding these requirements and providing the ideal substrate, temperature, humidity, and fresh air conditions. The process may require patience, but the reward of seeing your own mushrooms grow and tasting the fruits of your labor makes it all worthwhile.

Remember, it’s okay if you encounter challenges along the way. The journey of growing mushrooms is a learning experience, filled with opportunities for growth and discovery. In the world of mushroom cultivation, patience, persistence, and curiosity are your best friends. Happy growing!
