Getting Started: Equipment and Materials

Before you start growing your chestnut mushrooms, it’s essential to have the right equipment and materials on hand. Here are the necessary items you’ll need:



Mushroom spawn

Substrate (usually shredded straw or sawdust)

Growing container (could be a plastic bucket or bag)

A container for mixing the substrate and spawn

Thermometer and humidity meter

Hydrogen peroxide for sterilizing the container

Spray bottle for misting

Coffee grounds or calcium carbonate for adjusting pH levels

Once you have gathered all the necessary equipment and materials, you’ll be fully prepared to begin your mushroom-growing journey.

Preparing the Growing Container

Before you start growing chestnut mushrooms, it’s important to have a clean and sterilized growing container. This ensures your mushrooms grow in a healthy environment free from unwanted contaminants.

You will need the following items:

  1. A large plastic container with a lid
  2. A drill with a 1/4 inch bit
  3. A cheesecloth
  4. A pressure cooker
  5. Rubbing alcohol
  6. A pair of gloves

Follow these steps to prepare your growing container:

  1. Clean the container with soap and hot water.
  2. Drill several holes evenly spaced on the sides of the container for ventilation.
  3. Place the container and lid into a pressure cooker and steam for 1 hour at 15 psi.
  4. Put on gloves and use rubbing alcohol to sanitize the inside of the container and lid.
  5. Cover the container’s ventilation holes with cheesecloth to prevent contamination.

Your growing container is now ready for the next step – inoculating the substrate with mushroom spawn.

Inoculating the Substrate with Mushroom Spawn

Now that your growing container is ready, it’s time to move on to the next crucial step: inoculating the substrate with mushroom spawn. This process involves mixing the spawn with your chosen substrate to create an environment where the mushrooms can grow and flourish.

First, prepare your substrate by following the instructions provided with your mushroom spawn. Typically, you will need to hydrate the substrate and heat it to the appropriate temperature to kill off any potential contaminants.

Next, you’ll need to mix in the mushroom spawn. Depending on the type of spawn you’re using, the process may differ slightly. However, in general, you’ll simply need to spread the spawn evenly throughout the substrate and mix it in thoroughly using a sterilized spoon or spatula.

Once the spawn is mixed in, you’ll want to ensure that the substrate is kept at the optimal temperature and moisture level for your chosen mushroom variety. (Note: insert specific temperature and moisture requirements for chestnut mushrooms here, if relevant).

Pro Tip: Be sure to wear gloves and use sterile tools throughout the inoculation process to prevent contamination, which can lead to poor mushroom growth.

It’s crucial to mix the substrate and spawn thoroughly to ensure even colonization and healthy growth. Once you’ve mixed the two together, you’ll want to transfer the substrate to your growing container as quickly and efficiently as possible to minimize any potential contaminants.

With the substrate and spawn mixed and ready to go, you’re well on your way to growing delicious chestnut mushrooms in the comfort of your own home.

Providing the Right Conditions for Growth

Now that you have inoculated your substrate with mushroom spawn, it’s time to create the right conditions for your chestnut mushrooms to grow. Chestnut mushrooms require specific environmental conditions, including temperature, humidity, and light, to thrive and produce a bountiful harvest. Providing the ideal growing conditions is a crucial step in ensuring your mushrooms grow healthy and strong.


The ideal temperature range for growing chestnut mushrooms is between 55°F and 65°F. It’s essential to maintain a stable temperature within this range throughout the entire growing cycle. Fluctuations in temperature can cause stress to the mushrooms and impact their growth and yield.


Impact on Growth

Below 50°F

Growth slows or halts

Above 75°F

Fruiting bodies shrivel or do not form at all


Chestnut mushrooms require high humidity levels to develop properly. Aim to maintain a relative humidity level between 85% and 95% throughout the growing cycle. Misting the substrate and the walls of the growing container several times a day can help maintain the humidity levels.

Impact on Growth

Below 70%

Mushrooms may not form or grow to full size

Above 95%

Excessive moisture can lead to bacterial or mold growth


Chestnut mushrooms do not require light to grow, but they do require a little bit of light to initiate the fruiting phase. Indirect sunlight or low-level artificial light can provide enough light for the mushrooms to form fruiting bodies. Avoid exposing the growing container to direct sunlight or bright lights, which can cause overheating and drying out of the substrate.


Proper ventilation is crucial for ensuring the right temperature, humidity, and carbon dioxide levels. Good air exchange can also prevent the growth of unwanted contaminants. Provide fresh air by opening the lid of the growing container or using a fan to circulate the air inside the container.

By providing the right growing conditions, you’ll give your chestnut mushrooms the best chance to grow big and strong. In the next section, we’ll cover how to care for your growing mushrooms.

Caring for Your Growing Chestnut Mushrooms

As your chestnut mushrooms begin to grow, it’s important to provide them with proper care and attention. By following these simple steps, you’ll ensure that your mushrooms remain healthy and vibrant throughout their growth cycle.


Chestnut mushrooms need to be watered regularly to maintain proper moisture levels. However, overwatering can be detrimental to their growth. It’s important to strike a balance and not let the substrate become too dry or too wet. The best way to water your mushrooms is to mist them with a spray bottle. This will help prevent overwatering and ensure that the mushrooms have enough moisture to grow.

Maintaining Proper Conditions

It’s crucial to maintain proper environmental conditions for your chestnut mushrooms to grow. Keep the growing container in a cool, dark, and well-ventilated area. The ideal temperature for growth is between 60-68°F (15.5-20°C), and the humidity level should be around 85%. You can use a hygrometer to measure the humidity levels and adjust as needed. Additionally, providing proper ventilation will help prevent the buildup of carbon dioxide, which can harm your mushrooms.

Common Issues and Troubleshooting

Even with the best care, you may encounter some common issues while growing chestnut mushrooms. These can include issues such as yellowing or browning of the mushrooms, which can be caused by over or under watering. It’s important to monitor your mushrooms closely and adjust your care accordingly. If you notice any mold growth or unusual smells, it may be a sign of contamination, and you should remove any affected mushrooms immediately.

By following these tips and providing your chestnut mushrooms with the necessary care and attention, you’ll be rewarded with a bountiful and delicious harvest in no time.

Harvesting and Storing Your Chestnut Mushrooms

After weeks of nurturing your chestnut mushrooms, it’s finally time to harvest them. To ensure optimal flavor and longevity, it’s important to harvest your mushrooms at the right time and store them correctly.

Harvesting Your Chestnut Mushrooms

The ideal time to harvest your chestnut mushrooms is when the caps are fully grown but haven’t yet started to curl upwards. This is typically around 2-3 weeks after the pins first appear.

When harvesting, it’s essential to avoid damaging the mycelium, which is the thread-like network that supports the mushrooms. To do this, gently twist and pull the mushroom caps from the substrate, being careful not to pull too hard or use any tools that could damage the mycelium.

Storing Your Chestnut Mushrooms

Once harvested, it’s important to store your chestnut mushrooms properly to preserve their flavor and freshness. Here are some tips:

  1. Store your mushrooms in a paper bag or wrapped in a paper towel. Avoid using plastic bags, as they can trap moisture and cause the mushrooms to spoil more quickly.
  2. Keep your mushrooms in the refrigerator, ideally in the crisper drawer. Store them away from fruits and vegetables, as these can release ethylene gas, which can cause your mushrooms to spoil more quickly.
  3. Use your mushrooms within 3-5 days for optimal flavor and freshness. Alternatively, you can freeze your mushrooms for longer-term storage. To do this, slice the mushrooms and spread them out on a baking sheet. Place the sheet in the freezer until the mushrooms are frozen, then transfer them to a freezer bag and store in the freezer for up to 6 months.

By following these simple tips, you can ensure that your harvested chestnut mushrooms stay fresh and flavorful for as long as possible.
