How to Grow Mushrooms at Home: Tents, Grow Bags, and Mono Tubs

Learning how to grow mushrooms at home can be an exciting and rewarding journey, whether for culinary, medicinal, or hobby purposes. Mushroom cultivation at home is rewarding journey.

Let’s explore three popular methods for growing mushrooms: mushroom tents, grow bags, and mono tubs. Each method has its own advantages, and your choice will depend on your goals, space, and experience level.

Mushrooms thrive in precise conditions involving humidity, air circulation, temperature, and light. Without proper control, contamination, poor yields, or failed growth can occur. That’s why controlled grow environments are key to success.

Option 1: Mushroom Tents

A mushroom tent is a versatile system that provides a fully controlled microclimate for your mushrooms. One standout example is the Boom Room 2 from North Spore, which combines advanced technology and ease of use.

Key Features of Mushroom Tents:

Enhanced Humidity Control
The right humidity (typically 75%-85%) is vital for mushroom growth. Too little dries them out, while too much can lead to mold. Tents like the Boom Room 2 include humidifiers for even moisture distribution.

Fresh Air Exchange
Mushrooms breathe oxygen and release carbon dioxide. A good tent circulates fresh oxygen while removing CO2, mimicking natural conditions.

Space Efficiency
Compact designs allow for high yields in limited space. For instance, the Boom Room 2 has five tiers capable of holding 25-pound fruiting blocks, ideal for small apartments.

Waterproof Subfloor
Excess moisture can damage surfaces. Tents often include features like waterproof layers to protect your space and keep things clean.

Automation
Some tents allow for hands-free operation using float valves that automatically refill humidifiers, perfect for busy growers.

Why Choose a Tent?

• Perfect for: Those looking for precision and year-round cultivation.
• Best suited for: Serious growers or those growing both edible and medicinal mushrooms.
• Limitations: Higher upfront cost compared to simpler methods.

Option 2: Grow Bags

If you’re looking for simplicity, grow bags are an excellent choice. These sealed bags, filled with substrate (the nutrient-rich material mushrooms grow in), offer a low-maintenance way to cultivate mushrooms.

Once inoculated with mushroom spawn, the substrate in the bag begins colonization. Over time, mushrooms fruit directly inside the bag.

Why Grow Bags Are So Handy

Grow bags are super convenient for mushroom cultivation. You can either buy them pre-sterilized and ready to go or make your own by adding mushroom spawn to sterilized substrate. Their clear design makes it easy to keep an eye on progress without opening the bag, which helps prevent contamination. They’re also compact, so you can grow mushrooms in small spaces like a counter, closet, or shelf. Plus, many come with built-in air filters, ensuring proper airflow while keeping contaminants at bay.

• Perfect for: Beginners or casual growers with limited space.
• Best suited for: Small, low-maintenance grows.

Pros & Cons of Grow Bags:

✅ Pros:

• Beginner-friendly
• Low risk of contamination
• Minimal space required
• Great for small-scale grows

❌ Cons:

• Limited yield per bag
• Not ideal for large-scale cultivation
• Can produce plastic waste

Option 3: Mushroom Monotubs

For growers seeking higher yields and scalability, monotubs are a fantastic option. These plastic bins, often DIY-modified, are designed for bulk substrate and mushroom cultivation.

A mono tub creates a humid environment by combining substrate, mycelium (the mushroom’s vegetative part), and controlled airflow.

Key Features of Mono Tubs:

Mono tubs are perfect for bigger mushroom grows because they can hold more substrate than grow bags. If you like DIY, you can easily customize them by adding air holes and filters for better airflow, but there are also ready-made options like the Boomer Bin that save you the hassle. The sealed lid helps maintain humidity, while the air holes make sure CO2 is removed, creating the ideal environment for mushrooms to thrive. Plus, plastic bins are reusable, so over time, they’re a more cost-effective option.

• Perfect for: Intermediate growers or those seeking bulk cultivation.
• Best suited for: Hands-on growers comfortable with managing environmental variables.

Pros & Cons of Monotubs:

✅ Pros:

• Higher yields in one grow cycle
• Customizable for different mushroom species
• Reusable and scalable

❌ Cons:

• Requires more space than grow bags
• Hands-on monitoring needed for humidity and airflow
• Higher risk of contamination without proper sterilization

Option 4: Liquid Cultures – The Gateway to Scalable Mushroom Growing

Liquid cultures are a powerful and efficient method for propagating mushrooms. They involve growing mushroom mycelium in a nutrient-rich liquid medium, making it easy to inoculate large quantities of substrate or spawn quickly and efficiently. This method is perfect for intermediate to advanced growers or those looking to scale up their production.

A liquid culture is a sterile solution, typically made of water and a nutrient source like honey, malt extract, or corn syrup, that supports the growth of mushroom mycelium. Once the mycelium grows in the liquid, the culture can be injected into substrates (like grain or sawdust) to colonize them faster than traditional spawn.

🧪 How Do Liquid Cultures Work?

1. Preparation of the Medium
   A mixture of water and nutrients is sterilized to create a nutrient-rich environment where mycelium can grow.
2. Inoculation
   A small amount of mushroom spores or mycelium is added to the liquid medium in a sterile environment.
3. Mycelium Growth
   Over several days or weeks, the mycelium spreads throughout the liquid, creating a white, cloud-like network.
4. Inoculation of Substrates
   The liquid culture is drawn into a sterile syringe and injected into a substrate like grain bags or grow bags. The liquid mycelium spreads quickly through the substrate, jumpstarting the colonization process.

Liquid cultures make growing mushrooms much faster and easier. Instead of waiting for spores to do their thing, the mycelium in liquid cultures spreads quickly, colonizing substrates in no time. Plus, one jar can go a long way—it’s easy to scale up by inoculating multiple grow bags, jars, or bulk substrates. This makes it a cost-effective option since you can keep reusing and propagating your liquid cultures instead of buying new spawn. And the results? Faster growth and consistent, high-quality mushrooms.

Liquid cultures are super efficient—they grow evenly and colonize substrates quickly. You can also store them for months in the fridge, so they’re ready whenever you need them. Since every step involves sterilization, contamination risks are low, keeping the whole process clean and reliable.

✅ Pros:

• Fast Colonization: Mycelium spreads quickly, reducing the grow time.
• Reusable: A single jar can inoculate multiple substrates.
• Scalable: Ideal for large-scale cultivation.
• Customizable: You can grow liquid cultures for specific mushroom species.

❌ Cons:

• Requires Sterility: Contamination can ruin the entire liquid culture.
• More Hands-On: Sterilization and preparation take time and attention.
• Intermediate Skill Level: Beginners may find the process challenging at first.

Pro Tips for Using Liquid Cultures

1. Start Small: If you’re new to liquid cultures, practice on a small batch to perfect your sterilization technique.
2. Label Your Jars: Always mark the date and mushroom species to keep track of your cultures.
3. Sterility is Key: Use gloves, alcohol wipes, and a sterile workspace to avoid contamination.
4. Store Properly: Keep unused cultures in the refrigerator to extend their lifespan.

Liquid cultures are ideal for:

• Intermediate and advanced growers ready to scale up.
• Anyone looking to save money by producing their own spawn.
• Growers who want faster colonization times.

If you’re comfortable working with sterile environments and enjoy hands-on processes, liquid cultures are an excellent way to grow mushrooms more efficiently. Let me know if you’d like a deeper dive into specific liquid culture recipes or troubleshooting tips! 🌟

No matter which method you choose, understanding how to grow mushrooms at home starts with selecting the right environment

💡 Interesting Facts About Mushroom Cultivation

1. Mushrooms “breathe” just like humans. They inhale oxygen and exhale carbon dioxide, which is why airflow is so critical!
2. Not all mushrooms need darkness. While mushrooms don’t use light for energy like plants, light exposure influences their shape, color, and direction of growth.
3. Mycelium is the real worker. The mushrooms we eat are the fruiting bodies, but the hidden mycelium network does all the heavy lifting in colonizing the substrate.

With these methods, you now know how to grow mushrooms at home, making it easy to enjoy fresh, home-grown fungi year-round.
