How To Grow Mushrooms Indoors – Is It Worth It?
Interest in indoor gardening and health-boosting foods is growing. Because of this, more people are trying indoor mushroom farming. With simple setups like a Mushroom Grow Bag or a Monotub, it can be a tasty hobby that supports your well-being — or even a small source of income. This guide covers everything you need to know to start growing mushrooms indoors and will help you decide if it’s right for you, whether you want to grow for cooking, for health, or to start a small business.
Benefits of Growing Mushrooms Indoors
Growing mushrooms indoors offers many good things, not just fresh food. Here's why many people, like gardeners, chefs, health-minded people, and business owners, are now very interested in this hobby:
Year-Round Harvests
Traditional vegetable gardens need long daylight hours and specific outdoor temperatures. But mushrooms don’t. You can grow mushrooms indoors all year. You get fresh crops every few weeks, depending on the type. This is very good if you plan to eat mushrooms often or use them for a business.
Space-Efficient and Apartment-Friendly
Mushrooms grow well in small spaces. You can stack grow bags up or use small shelves. This means you can turn just a few square feet into a farm. Any place with low light, like a closet or kitchen counter, can become a small mushroom farm.
Controlled Environment for Reliable Yields
Growing mushrooms indoors works best when you control the conditions. Indoors, you are in charge of this. You can adjust the temperature, humidity, airflow, and light. This helps you make the best growing place for certain types of mushrooms. It leads to more good harvests and fewer problems compared to growing outside.
Pest-Resistant and Weather-Proof
When growing outside, people often fight slugs, insects, changing moisture, and wild animals. But indoors, these problems mostly go away. This greatly improves how well new growers do. Plus, there is less chance of soil diseases or bad fungi ruining the crop.
Health-Boosting Benefits
Mushrooms like Lion's Mane, Reishi, and Shiitake are known to have health benefits. They can help your immune system, act as antioxidants, reduce swelling, and even improve brain function. When you grow your own, you get these helpful compounds directly. (Stamets, 2005)
Mindfulness and Mental Well-Being
There's a therapeutic rhythm to indoor mushroom growing. The daily care ritual offers a meditative routine, helping reduce stress and improve focus. Watching mushrooms colonize and fruit can be unexpectedly emotional—and deeply satisfying.
Is Growing Mushrooms at Home Worth It?
Growing mushrooms indoors offers more than just money saved or earned.
Cost Efficiency
Starter kits might cost $20–$40, but they can give you many pounds of fresh mushrooms. If you often buy organic mushrooms for $10–$20 per pound, you can make your money back fast. And then, as you get better at it, you can move to bigger batches of growing material and cultures. This will make your cost per pound even less.
Long-Term Value and Self-Sufficiency
Even small setups give you good food when it's hard to get groceries. For example, during bad weather or supply chain issues. Growing your own means fresh, good quality food. And you know exactly how your mushrooms were grown.
Health as an Investment
Mushrooms help with many things, from immune system changes to brain health. They have nutrients most other plant foods do not. For example, Shiitake has beta-glucans and lentinan. These compounds are known to make immune cells more active and lower swelling (Vetvicka & Vetvickova, 2011).
Profitability Potential
Once you learn how, you can make money from indoor mushroom farming. Fancy kinds, like Lion’s Mane, sell for high prices in stores—up to $20 per pound fresh, or even more when dried. If you grow a lot and use equipment again, you can make good profit with low costs.
Emotional and Mental Rewards
There is a value you can't touch in seeing a mushroom grow. Watching fluffy white mycelium spread and then turn into colorful fruiting bodies can feel both amazing and inspiring.
Best Mushroom Varieties for Indoor Cultivation
Each mushroom type has its own traits. These affect how easy it is to grow, its taste, and what good things it does for you. Here are the best kinds for growing indoors.
Oyster Mushrooms (Pleurotus)
- Growth Speed: Among the fastest-growing mushrooms; they can fruit in as little as 10–14 days after colonization.

- Why They're Great: Good for those who enjoy classic kitchen staples with predictable results.
What Equipment Do You Need to Grow Mushrooms Indoors?
Your equipment can be very simple or quite advanced, depending on the type of setup you want.
Starter Supplies
- Spawn: Living mushroom culture, available as grain spawn or sawdust spawn.
- Substrate: Nutrient-rich base (straw, hardwood pellets, or coco coir).
- Growing Bags or Containers: Poly bags with microfilters are ideal to maintain sterile airflow.
- Water Management: Misting bottles, greenhouse humidifiers, or ultrasonic foggers.
- Lighting: Mushrooms only need a small amount of indirect light; even a desk lamp can suffice.
Beginner-Friendly Grow Kits
Many first-time growers choose preassembled kits from good sellers like Zombie Mushrooms. These kits include everything needed: colonized substrate blocks, grow bags, and detailed instructions. It's a low-risk way to get your first successful harvest.
Intermediate to Advanced Gear
- Fruiting Chambers: Totes or tents fitted with misting systems, fans, and timers.
- Sterile Workspaces: Still air boxes or laminar flow hoods.
- Labs Tools: Liquid culture syringes, agar plates, and autoclaves enable culture cloning and strain preservation.
Creating the Ideal Indoor Growing Conditions
Each stage of mushroom growth needs specific conditions.
- Temperature: 60–75°F is suitable for most species. Too hot or too cold stops growth and causes contamination.
- Humidity: Fruiting bodies need 85–95% humidity to develop properly; consider a hygrometer to monitor levels.
- Light: While not dependent on photosynthesis, light triggers pinning—the start of fruiting. Use a 12-hour on/off cycle.
- CO₂ Exchange: Mycelium releases CO₂; stagnant air can choke growth. Install small fans or mist near open windows.
- Cleanliness: Keep hands, tools, and surfaces clean to avoid introducing mold or bacteria.
Step-by-Step: How to Grow Mushrooms Indoors
1. Inoculation
Thoroughly sanitize all equipment. Mix your spawn into a pasteurized or sterilized substrate, then place into your container or grow bag. Seal and label.
2. Colonization
Store in a dark, stable-temperature area. Mycelium will spread across the substrate, turning it white. This phase lasts between 2–4 weeks depending on the species and conditions.
3. Fruiting
Expose colonized substrate to fresh air, indirect light, and high humidity. Use a spray bottle or humidifier to create a moist microclimate. Small mushroom pins will appear in a few days.
4. Harvest
Use a clean knife or twist off fruits when the caps open and gills are defined (before spore drop). Handle gently and store in paper bags or refrigerate immediately.
5. Second and Third Flushes
Allow the substrate to rest for a few days, then resume misting. Most blocks can produce 2–3 flushes before becoming spent.
Mushroom Farming for Profit — Microbusiness Realities
Reports from Grand View Research say the world mushroom market will reach over $50 billion by 2028. People want more food that acts like medicine and more plant-based protein. So, small growers are in a good spot to get into this profitable part of the market.
Where to Sell
- Farmers Markets: Sell to people who care about health and local products.
