Supplies You’ll Need
Before starting, gather a few basic supplies. Most of these are easily available online or at local garden stores in the U.S.
- Mushroom spawn or spores (depending on the type of mushroom)
- Growing medium (straw, sawdust, coffee grounds, or compost)
- Plastic containers or grow bags
- Spray bottle for misting
- Thermometer and humidity meter
- Dark, humid space (like a closet, basement, or grow tent)
Step-by-Step Guide to Growing Mushrooms Indoors
Step 1: Prepare the Growing Medium
Start by sterilizing your chosen substrate (straw, sawdust, or coffee grounds). You can boil it or microwave it to kill any bacteria. Once cooled, place it in your container or grow bag.
Step 2: Add the Mushroom Spawn
Mix your mushroom spawn evenly into the growing medium. Make sure it’s well distributed so the mycelium (the root-like structure of mushrooms) can spread properly.
Step 3: Incubation Period
Keep your container in a dark, warm space at around 70–75°F (21–24°C). Over the next 2–3 weeks, the mycelium will grow and colonize the medium. You’ll see white thread-like growth spreading through the substrate that’s a good sign!
Step 4: Initiate Fruiting
Once the substrate is fully colonized, lower the temperature to 55–65°F (12–18°C) and increase humidity. You can do this by misting water several times a day or using a humidifier. Provide some indirect light mushrooms don’t need sunlight but a little light helps them form properly.
Step 5: Harvest Time!
In about a week or two, small mushroom pins will start appearing. Let them grow for a few more days until they reach full size. Gently twist and pull them from the base avoid cutting with a knife as it can damage the next batch.
Tips for Successful Organic Mushroom Farming
- Use organic substrate: Choose chemical-free straw or coffee grounds for a cleaner crop.
- Maintain humidity: Mushrooms love moisture. Mist regularly but don’t overwater.
- Avoid contamination: Keep your hands and tools clean. Any mold or bacteria can ruin the batch.
- Recycle substrate: After harvesting, you can compost the used substrate for your garden.
By following these eco-friendly methods, you can enjoy fresh, healthy mushrooms all year long.

Cost and Time Investment
Starting an indoor mushroom garden is affordable. A basic kit costs around $20–$40, and you can expect your first harvest within 4-6 weeks.
Compared to buying organic mushrooms from grocery stores, home-growing is a cost-effective option that pays off in the long run.
Common Mistakes to Avoid
- Too much sunlight: Mushrooms grow best in dim light.
