Getting to Know Mushrooms and How They Grow

Let’s start with the basics. Mushrooms aren’t plants—they’re fungi. And the part we eat is just the fruit. Underneath it all is something called mycelium, which acts like the root system. The whole process begins with spores (tiny reproductive cells), which grow into mycelium. That mycelium then spreads through the growing material—called the substrate—and eventually produces mushrooms when conditions are just right.

The life cycle includes spore germination, mycelium colonization, fruiting, and finally, harvest. Understanding this flow helps you set things up at each step.

Choosing Which Mushrooms to Grow

There are a lot of mushroom varieties out there, but some are better for beginners.

Great options for home growing:

• Oyster mushrooms: Super forgiving and grow fast.
• White button mushrooms: The most common type you see in stores.
• Shiitake mushrooms: Packed with umami and great for hardwood logs or sawdust.
• Lion’s mane: A bit more advanced but offers a unique seafood-like texture.

If it’s your first time, oyster mushrooms are a solid pick since they’re tough to mess up and grow well on a wide range of materials.

Setting Up the Perfect Growing Environment

Mushrooms aren’t too picky, but they do have a few basic needs.

• Temperature and humidity: Most mushrooms grow best between 55 and 75 degrees Fahrenheit. Keep humidity high—around 80% to 95%. A spray bottle or humidifier helps maintain moisture.
• Light: Mushrooms prefer indirect light or fluorescent lighting. They don’t need full sun exposure.
• Air circulation: Proper airflow prevents carbon dioxide buildup. A small fan or opening the containers for a few minutes daily can help.
• Containers: Plastic tubs, trays, or growing bags work well indoors. For outdoor growing, hardwood logs or raised beds can be great choices.

Picking the Right Substrate (Growing Material)

Mushrooms feed off the material they grow in, so choosing the right substrate is important.

Popular substrate choices:

• Straw: Great for oyster mushrooms.
• Hardwood sawdust: Perfect for shiitakes and lion’s mane.
• Coffee grounds: Nutrient-rich and eco-friendly.
• Composted manure: Ideal for white button mushrooms.

Cleaning the substrate: Sterilize or pasteurize the material before using it. For sawdust or grains, use a pressure cooker at 15 PSI for 90 minutes. For straw, soak it in hot water at 160°F for one hour. This removes contaminants that can ruin your batch.

How to Inoculate the Substrate

Once your substrate is clean and cooled, it’s time to add mushroom spawn.

Steps for inoculation:

1. Clean your hands, tools, and surfaces with alcohol.
2. Evenly mix the spawn into the substrate.
3. Pack the mix into containers or grow bags.
4. Cover with a breathable lid or filter to allow air exchange.
5. Store in a warm, dark place for incubation.

This is when the mycelium begins spreading and colonizing the substrate.

What Happens During the Incubation Period

During incubation, the mycelium takes over the substrate. This step can take two to four weeks depending on your setup and mushroom type.

• Incubation conditions: Just keep your containers in a dark spot at around 70–75 °F. Once the top’s totally white and fluffy, you’re ready to move on to fruiting.

Getting Mushrooms to Fruit

Once the mycelium has colonized the substrate, it’s time to help it produce mushrooms.

To trigger fruiting:

• Lower the temperature slightly to around 60–65°F.
• Increase humidity to 90% or more using a misting bottle or covering the container.
• Introduce some indirect light or soft grow lighting.
• Allow fresh air in daily with gentle airflow or lid openings.

Within a few days, you’ll start seeing tiny pins appear. These are the beginnings of your mushrooms.

Common Problems and How to Fix Them

Things don’t always go as planned, especially when you’re new.

Common issues and fixes:

• Contamination: If you see green mold or smell something foul, throw out the batch. It means your substrate wasn’t sterile enough.
• No mushrooms: Could be too dry, too dark, or not enough air. Adjust moisture and light levels.
• Slow growth: The substrate might be lacking nutrients. Make sure you’re using fresh spawn and quality materials.

Stay clean, monitor your conditions, and you’ll reduce your chances of problems.

Harvesting and Storing Your Mushrooms

Mushrooms grow quickly, so keep a close eye on them.

• When to harvest: Pick them before the caps fully open. This is when flavor is at its peak.
• How to harvest: Gently twist or cut the mushrooms at the base. Don’t yank them—it can damage the substrate.
• Storing mushrooms: Place fresh mushrooms in a paper bag in the fridge. They’ll last up to a week. To store long-term, dry them in the sun or a dehydrator. You can also cook and freeze them for ready-to-go meals.

Helpful Tips for Future Batches

As you grow more mushrooms, you’ll develop a feel for the process.

Tips for long-term success:

• Keep a journal: Note temperatures, humidity, and outcomes for each batch.
• Reuse spawn: You can make spore prints to keep costs low.
• Try new types: Once you master one kind, experiment with others to expand your skills.

Each cycle gets easier, and your harvests get better with practice.

Conclusion

Growing mushrooms at home is fun, affordable, and surprisingly simple. Whether you’re using straw, sawdust, or coffee grounds, you can create a productive setup right in your home. With patience and consistency, you’ll be harvesting delicious mushrooms regularly. Stick with it, tweak your setup as needed, and enjoy the satisfaction of homegrown fungi.

Key takeaway: Growing mushrooms at home is totally doable. Once you choose the right kind, set up the proper environment, and manage moisture and temperature, you’ll be harvesting fresh mushrooms like a pro.

FAQs

Can I grow mushrooms from store-bought mushrooms?

Yes, but results vary. You can sometimes clone them using the stem, but success depends on how fresh they are and how they were handled.

Do mushrooms attract bugs or pests indoors?

Not usually. If you maintain cleanliness and avoid overwatering, you’re unlikely to see pests.

Is it safe to grow different mushroom types together?

You can, but it’s not ideal. Different species often require different conditions, so growing them separately is usually better.

Can kids help with mushroom growing?

Definitely. It’s a great hands-on science activity. Just be sure to manage the sterilization steps yourself.

How do I know if my mushrooms are ready to pick?

Harvest them before the cap completely flattens out. That’s when the flavor and texture are best.
