How To Grow Mushrooms: The Ultimate Guide


Learning how to grow mushrooms at home is a fun family-friendly project that requires little space and no gardening experience.

Whether you're a hobbyist looking to grow gourmet mushrooms at home or someone interested in growing mushrooms at scale, this guide will walk you through the essential steps to ensure a successful harvest.

By understanding the various substrates, types of spawn, and the specific needs of your chosen mushroom species, you'll be well on your way to growing mushrooms.

How To Grow Mushrooms

Choosing Your Mushroom Species:

The first step in your mushroom cultivation journey is to determine which species of mushroom you want to grow.

Popular choices include oyster mushrooms, shiitake, and button mushrooms, each with its own specific growing requirements and environmental preferences.

Consider factors such as taste, growing conditions, and the space you have available when making your choice.

We have an easy-to-understand breakdown of the best mushrooms to grow each with its benefits. More to come below.

Selecting a Substrate:

Mushrooms are not plants; they require a nutrient-rich growing medium called substrate to grow. The substrate acts as a source of food for your mushrooms, and the type you choose can significantly affect your yield. Common substrates include:

Straw:

Ideal for oyster mushrooms, straw is inexpensive and easy to prepare.

Sawdust:

Rich in cellulose, sawdust is perfect for shiitake mushrooms.

Wood Chips:

Rich in cellulose, sawdust is perfect for shiitake mushrooms.

Compost:

Suitable for use with all compost-loving mushroom spores.

Manure:

Button mushrooms thrive in a composted straw and manure mix.

Coffee Grounds:

An excellent way to recycle, coffee grounds are suitable for smaller-scale cultivation.

Preparation of the substrate often involves pasteurization or sterilization to kill any unwanted bacteria or fungi.

Obtaining Mushroom Spawn:

Spawn acts as the "seed" from which your mushrooms will grow. It's essentially mycelium (the vegetative part of the fungus) colonizing a substrate, such as grains or sawdust.

You can purchase mushroom spawn from reputable suppliers, ensuring it's suitable for your chosen substrate and mushroom species.

Inoculation:

Inoculation is the process of introducing mushroom spawn to your prepared substrate. This step must be done in a clean environment to prevent contamination.

Spread the spawn evenly throughout the substrate, ensuring it's thoroughly mixed for the best results.

Incubation:

After inoculation, place your substrate with the spawn in a dark, warm place to encourage mycelium growth. This growth phase is critical and can take several weeks, depending on the mushroom species.

The ideal temperature and humidity level will vary, so research your specific mushroom's requirements.

Fruiting:

Once the mycelium has fully colonized the substrate, it's time to induce fruiting. This usually involves exposing the mycelium to lower temperatures, higher humidity, and indirect light.

These conditions signal to the mycelium that it's time to produce mushrooms. Fruiting chambers or grow tents can help maintain these conditions.

Harvesting:

Mushrooms grow quickly once they start to appear. Check your crops daily, and harvest them by gently twisting and pulling them from the substrate. Make sure to do this only when they're fully grown but before the caps fully open.

Harvesting at the right time ensures the best flavor and texture.

Post-Harvest Processing:

After harvesting, mushrooms are often processed, which can include cleaning, sorting, packaging, and, in some cases, drying or freezing.

Preparing for the Next Cycle:

After harvest, the substrate can sometimes be reused for another cycle, although its effectiveness diminishes with each use.

Each step in the process requires careful management to ensure the optimal mushroom growth. Environmental conditions like temperature, humidity, and cleanliness are particularly crucial throughout the cultivation process.

Ensure Success With An Easy-to-Use Mushroom Grow Kit

Using a mushroom growing kit is an excellent way for beginners to start their journey into mushroom cultivation. Mushroom kits are also great for seasoned growers to test new varieties without extra preparation or equipment.

Mushroom growing kits provide tons of benefits such as simplicity, convenience, and a high success rate. They are great as gifts and are perfect for those in small spaces such as urban environments with limited outdoor space.

What Are The Best Varieties of Mushrooms To Grow

The best varieties of mushrooms to grow depend on several factors. This includes your growing environment, the level of effort you're willing to invest, and whether you plan to eat or sell the mushrooms.

Some mushroom varieties are easier to cultivate and are great for beginners. However, others require more specialized conditions but can offer unique flavors or higher market value. Here's a look at some popular varieties that cater to a range of preferences and purposes:

Choosing Your Mushroom Species

Oyster Mushrooms (Pleurotus Ostreatus)

Why We Like Them: Oyster mushrooms are one of the easiest and fastest-growing varieties. They can thrive on a variety of substrates, including straw, coffee grounds, and sawdust.

Benefits: They have a mild flavor and a wide culinary use. Plus, their rapid growth cycle allows for quick harvests.

Shiitake Mushrooms (Lentinula Edodes)

Why We Like Them: Shiitake mushrooms are highly sought after for their rich flavor and health benefits. They're traditionally grown on hardwood logs or sawdust blocks.

Benefits: Shiitake can offer a higher market price and are known for their medicinal properties.

Button Mushrooms (Agaricus Bisporus)

Why We Like Them: Also known as white mushrooms, they're the most commonly consumed variety worldwide. They're typically grown in composted manure and require a bit more care in terms of humidity and temperature control.

Benefits: Their familiar flavor and texture make them a staple in various dishes.

Lion's Mane (Hericium Erinaceus)

Why We Like Them: Lion's mane mushrooms are recognized for their unique appearance and brain health benefits. They grow well on hardwood substrates.

Benefits: Unique in both texture and flavor, they're gaining popularity in gourmet cooking and as a nutritional supplement.

Portobello Mushrooms (Agaricus Bisporus)

Why We Like Them: Essentially mature button mushrooms, Portobellos have a meatier texture and more intense flavor. They're grown under similar conditions as button mushrooms.

Benefits: Ideal for grilling and stuffing, Portobellos are a favorite for vegetarian dishes.

Enoki Mushrooms (Flammulina Velutipes)

Why We Like Them: Enoki mushrooms have a delicate flavor and a crunchy texture, thriving in cooler temperatures. They're grown in jars or bags with a tight atmosphere to encourage their long, slender shape.

Benefits: Popular in Asian cuisine, they add texture and visual appeal to dishes.

Reishi Mushrooms (Ganoderma Lucidum)

Why We Like Them: Reishi are more often grown for their medicinal properties than for culinary use, as they're quite bitter. They can be cultivated on hardwood logs or sawdust.

Benefits: Reishi mushrooms are valued for their potential immune-boosting effects.

Choosing the Right Mushroom Variety:

When selecting mushrooms to grow, consider your growing space, the amount of time you can dedicate to cultivation, and your end goals.

Some mushrooms, like oysters and shiitakes, are forgiving and well-suited to beginners. In contrast, others, like reishi, might appeal more to those interested in the medicinal properties of fungi.

Regardless of the variety you select, growing mushrooms can be a rewarding experience, providing fresh produce for eating or products for your business.

Testing with different types can also be a fun process, leading you to discover new tastes and cultivation techniques.

Tips About How To Grow Mushrooms:

Maintain Cleanliness: Always work in a clean area to prevent contamination of your substrate and spawn.

Monitor Conditions: Regularly check temperature, humidity, and light conditions to ensure they meet your mushroom species' specific requirements.

Patience is Key: Mushroom cultivation can be a waiting game, especially during the incubation phase. Patience and careful monitoring will pay off with a bountiful harvest.

Frequently Asked Questions (FAQs):

Q: How long does it take to grow mushrooms?

A: The time from inoculation to harvest varies by species but typically ranges from a few weeks to several months.

Q: Can I grow mushrooms outdoors?

A: Yes, some species like shiitake can be grown on logs outdoors, but environmental control is more challenging.

Q: Do mushrooms need light to grow?

A: Mushrooms require indirect light to fruit properly. Unlike plants, they do not use photosynthesis, but light signals the fungi to start the fruiting process.

Q: What are mushroom spores?

A: Spores are the reproductive units of fungi, including mushrooms. They are analogous to seeds in plants but are microscopic.

Spores are produced by mature mushrooms and released into the environment to germinate and form new mycelial networks (the vegetative part of a fungus). When conditions are right, spores will germinate and grow into new fungal colonies.
