How To Grow Mushrooms Naturally At Home

There are several ways to grow mushrooms naturally at home, and the best method for you will depend on your experience level, the type of mushrooms you want to grow, and the space you have available. Here are three popular methods:

Using a Grow Kit:

This is the easiest method for beginners, as it requires minimal effort and setup. You can purchase a grow kit online or at many garden stores. The kit will come with everything you need, including a substrate (such as sawdust or straw) that has already been inoculated with mushroom spawn.

Using Spawn and Substrate

This method is a bit more challenging than using a grow kit, but it gives you more control over the type of mushrooms you grow. You can purchase mushroom spores or spawn online or from some specialty stores.

Growing on Logs

This method is the most natural way to grow mushrooms, although it does require a longer duration compared to the other two methods. To grow using this approach, you will need to find a fresh hardwood log that is at least 4-6 inches in diameter.

Growing mushrooms from a grow kit is a relatively simple process, and many kits are designed for beginners. Just remember to wash your hands before getting started with a grow kit to minimize the risk of contamination.

Materials Needed

• Mushroom grow kit: Purchase a mushroom grow kit from a reputable supplier. This kit includes a substrate inoculated with mushroom spores or mycelium.
• Spray bottle: For misting water.
• Optional: Thermometer and hygrometer (to monitor temperature and humidity).

Prepare Your Kit

Before going through this process, firstly find a suitable location for your grow kit. Make sure it is out of direct sunlight but receiving slightly indirect light. Maintain a temperature around 68 to 77°F, and keep the humidity level around 80 to 90% to promote successful mycelium growth. You can use a thermometer and hygrometer to monitor if these conditions are being maintained or not.

Soaking

Some kits require soaking before fruiting. If this is the case for your kit, follow the instructions that came with it. This usually involves soaking the kit in water for a few hours.

Fruiting

Once you have completed the soaking period, mist the kit with clean water and fan it gently to introduce fresh air. You’ll need to do this several times a day, depending on the humidity level. Don’t flood the kit, but make sure the surface of the substrate stays moist.

Pinning

After a few days, tiny white bumps will appear on the surface of the substrate. These pins are a sign that your mushrooms are starting to grow. This process is also referred to as pinning or primordia formation.

Harvesting

When your mushrooms are fully mature, it’s time to harvest them. You can do this by gently twisting them at the base. However, avoid pulling them, as this could damage the mycelium, the vegetative part of the fungus.

Second flush

After your first harvest, you can encourage more mushrooms from your kit by consistently misting and fanning it. Watch for the emergence of new small mushrooms, known as pins. If you want to know whether it’s time to harvest again, check the caps of the mushrooms.

If you are looking for a different way to get a second crop, try mixing the used mushroom kit stuff with things like sawdust, coffee grounds, or straw in a big bucket or container. That mix can help grow more mushrooms.

Extra Tips

• Use clean water to avoid contaminating your kit.
• Don’t overmist the kit, as this can lead to mold growth.
• It may take a few weeks for your mushrooms to grow, so keep your patience.

Gather Your Supplies

Spawn: 

Choose spawn varieties specific to the type of mushroom you want to grow. Spawn is the living seed of the mushroom, usually consisting of mycelium grown on sterilized grains like rye or millet. You can purchase this online or at some garden stores.

Substrate: 

Select a substrate suitable for your chosen mushroom variety. This serves as the food source for the mushrooms, providing nutrients and moisture for growth. Some popular substrate options include straw, sawdust, wood chips, or commercially prepared mushroom growing blocks.

Growing container: 

Pick any clean container with proper drainage holes, such as buckets, bins, or grow bags, choosing a size that accommodates the amount of substrate you will be using.

Gloves and mask: 

Wear gloves and a mask when handling spawn and substrate. It is essential to maintain hygiene, especially when dealing with bulk quantities.

Spray bottle: For misting the substrate to maintain humidity.

Prepare Your Container

If you are using a bucket, then drill holes for aeration in the sides and bottom of it. Wash and sterilize the container with a bleach solution or rubbing alcohol.

Hydrate the Substrate

While using a pre-pasteurized substrate, simply add water according to the instructions. If you are preparing your own, soak the substrate in hot water for several hours, then drain and squeeze out excess water. The substrate should be damp but not soggy.

Layer the Container

Add a layer of substrate to the bottom of your container. Next, sprinkle spawn evenly over the substrate, breaking up any large clumps. Then, add another layer of substrate on top, covering the spawn without compacting it.

Maintain Optimal Conditions

Mist the walls of the container regularly to maintain humidity, and avoid direct sunlight. You can also place your container in a humid location like a basement, but make sure it is maintaining around 80-90% humidity and a temperature of 65-75°F.

Harvest Your Mushroom

After a few weeks, or depending on the variety and growing conditions, your mushrooms will be ready to harvest. Once mushrooms appear, gently twist or cut them at the base. Avoid pulling to prevent damage to the mycelium. Harvest mushrooms before they become overripe or slimy.

Choose Your Spawn and Logs

Decide on the mushroom variety you want to grow. Purchase spawn plugs or dowels inoculated with the specific mycelium. Opt for hardwood logs like oak, maple, beech, or birch, preferably freshly cut and 3 to 6 inches in diameter, and 3 to 6 feet long. Avoid logs with signs of rot or disease.

Inoculation

Use a 1/2-inch drill bit to create holes in a staggered diamond pattern across the log surface, spacing them 4 to 6 inches apart. Avoid drilling too close to the ends or bark to prevent cracking. Place spawn plugs or dowels into the holes, ensuring they are flush with the surface. Melt wax and use a paintbrush to cover the holes, preventing contamination and moisture.

Incubation

Place the inoculated logs in a humid, shaded area with good air circulation. You may put them in a shaded corner of your yard, under a tree canopy, or in a shaded greenhouse. Keep the logs moist but not soggy. You can mist them, submerge them briefly in water, or build a covered structure around them to retain moisture. The colonization process can take several months.

Fruiting and Harvest

After colonization, initiate fruiting by soaking the logs in cold water for 12 to 24 hours. This mimics rainfall and encourages mushroom formation. Keep the logs moist during fruiting, similar to the incubation stage. After a few months, new mushrooms will appear. Harvest them gently when they reach their prime size. Leave a small portion of the stem attached to the log for future flushes.

Oyster mushrooms

These are some of the easiest and fastest-growing mushrooms, making them perfect for beginners. These mushrooms come in a variety of colors, including pearl oyster, king oyster, and pink oyster, and they thrive on a substrate of straw, sawdust, or coffee grounds.

Shiitake mushrooms

These flavorful mushrooms are a bit more challenging to grow than oyster mushrooms, but they are still relatively easy to manage. These mushrooms require a substrate of hardwood logs or sawdust, and they take a few months to fruit.

Lion’s mane mushrooms

These unique-looking mushrooms have a poofy, white appearance and are said to have health benefits. They are a bit more challenging to grow than some other mushrooms, but they’re still doable for home growers. They require a substrate of sawdust or hardwood logs, and they take several months to fruit.

Wine cap mushrooms

These vibrant purple mushrooms grow readily on straw or wood chips and are known for their earthy, meaty flavor. They are relatively easy to cultivate and produce flushes of mushrooms throughout the season.

Button mushrooms 

These are the classic white mushrooms that you find in most grocery stores. These mushrooms are not the easiest to grow at home, but they are possible if you show a bit of effort. They require a substrate of composted manure, and they take several weeks to fruit.
