Growing Mushrooms
Mushrooms are a type of fungi found in a variety of habitats all around the world. They can be classified into two main groups: edible and poisonous. Edible mushrooms provide a variety of vitamins, minerals and antioxidants, while poisonous mushrooms can cause a range of mild to deadly symptoms when consumed. In some societies, mushrooms are cultivated for food, while in others they are used for medicinal purposes.

Cheatsheet: How To Grow Mushrooms
Choose the Right Mushroom
🍄 Select a mushroom variety based on taste and ease of growth.
Create the Ideal Growing Environment
🌱 Provide temperatures between 65-75°F and high humidity.
Prepare the Growing Medium
🌾 Use compost, straw, or sawdust to create a nutrient-rich substrate.
Spawn Inoculation
🔬 Mix spawn with growing medium to introduce mushroom mycelium.
Maintain Optimal Conditions
💧 Keep the substrate damp and mist regularly to maintain moisture.
Provide Proper Ventilation
💨 Allow fresh air exchange to prevent contamination and promote growth.
Monitor for Pests and Diseases
🐜🍄 Keep an eye out for pests and diseases and take immediate action.
Harvest at the Right Time
🌸 Harvest mushrooms when the caps fully expand but before spores release.

Did You Know?
🌍 Cultivating mushrooms helps reduce waste and promotes sustainability.
Growing Mushrooms
The Basics
First, choose your mushroom type. Oyster and shiitake are great for beginners. They're forgiving and yield bountifully.
Mushrooms need a cool, dark, and humid environment—to mimic the forest floor. A basement or a dark closet works perfectly.
Optimal growing temperature is between 55°F and 60°F.
You’ll be amazed at how fast they grow once you get everything right. Trust me, it's almost magical.
Materials You'll Need
Get a mushroom growing kit or source pure mushroom spawn. Kits simplify this, making them perfect for novices.
- Mushroom spores or spawn
- Substrate (straw, sawdust, or logs)
- Misting bottle
- Plastic bags or containers
Substrate material varies by mushroom type. Straw works well for oyster mushrooms. Logs are best for shiitakes.
Setting Up Your Growing Environment
Sterilization is vital. Clean all tools and the environment to keep mold at bay. Contaminants can wreck a batch before you even see a sprout.
Create small holes (about 1 inch apart) in your plastic bags or containers to allow for proper air exchange. Increased humidity helps mushrooms thrive, but stagnant, moist air invites unwanted mold.
Substrate Preparation
For straw, pasteurize it by soaking it in hot water (160°F) for an hour. This kills off many undesirable organisms.
If using sawdust or logs, ensure they're freshly cut and uncontaminated. You'll need to inoculate your logs with mushroom spawn, which is an adventure on its own.
Logs should age slightly (2-3 weeks) before inoculating to prevent natural compounds from inhibiting growth.
Inoculating Your Substrate
Mix your mushroom spawn thoroughly with the prepped substrate. Ensure the spawn is evenly dispersed to promote uniform growth.
- Fill the plastic bag or container halfway with the mix.
- Compress it lightly to reduce air pockets.
- Seal the container, but remember the holes!.
Patience. This phase might take several weeks. Keep your setup in a cool, dark place and mist daily to maintain high humidity.
Monitoring and Maintenance
Check moisture levels religiously. Too dry, and your spores wither. Too wet, and you invite mold.
When white, thread-like mycelium covers your substrate, it's time for fruiting. Move your container to an area with indirect light.
Increase humidity. I often use a tent made from a plastic sheet draped over a frame.
Humidity should be around 90% during the fruiting stage.
Fruiting can take 7 to 14 days. You'll start seeing tiny mushroom pins first. Be ready to harvest in a day or two once they emerge.
Harvesting
Picking is easy. Gently twist and pull, or use a sharp knife to cut at the base. Collect them right before the veil under the cap breaks for the best flavor.
Regularly picking ensures continuous growth. Think of it as encouraging your mushrooms to keep producing.
Remember, mushrooms bruise easily. Handle them gently, like the delicate treasures they are.
Final Thoughts
Be prepared for an occasional batch failure. I've lost some to mold despite my best efforts. Just adjust and try again.
The joy of seeing those little caps pushing through makes it worth every bit of effort.
