Quick Tips

Keep the air moving: Lion’s mane mushrooms need high humidity, but stagnant air can lead to mold and contamination. Keep the air circulating with a fan or open windows to prevent issues down the line.

Moisture is vital: These mushrooms need consistent moisture, but be careful not to overdo it. Too much water can lead to bacterial or fungal growth, while too little can stunt growth. Keep an eye on moisture levels and adjust as needed.

Practice patience: Growing lion’s mane mushrooms can take time, so be patient!

Substrate Preparation

When growing lion’s mane mushrooms, choosing a suitable substrate is critical. Here are some of the most common substrates used for growing lion’s mane and how to prepare and inoculate them:

  • Hardwood sawdust: Sawdust from hardwood trees, such as oak or maple, is an excellent substrate for lion’s mane mushrooms. It must undergo sterilization by boiling or steaming, then mixed with gypsum and bran to provide additional nutrients for the mycelium. Once the sawdust mixture has cooled, it can be inoculated with the mushroom spawn using a sterile technique, such as a laminar flow hood or glove box.

 

  • Straw: While less common than hardwood sawdust, straw can also make an excellent substrate for lion’s mane mushrooms. The straw should be chopped into small pieces and soaked in water for several hours to soften it. After draining off excess water, the straw can be sterilized and mixed with bran and gypsum before inoculation with the mushroom spawn.

 

  • Logs: Growing lion’s mane mushrooms on logs is a more natural and sustainable option. The logs should be from hardwood trees, such as oak or maple, and cut to the appropriate length and diameter. Remove the bark, soak the logs in water for 24-48 hours to re-hydrate them. Drain the logs, and inoculate with the mushroom spawn by drilling holes into the logs and inserting spawn plugs. Seal the holes with wax to prevent contamination.

 

Regardless of the substrate chosen, using high-quality spawn and maintaining a sterile environment during the inoculation process is essential. Once the mycelium fully colonizes the substrate, it’s time for fruiting. At this stage, the substrate should be moved to an environment with high humidity and proper air circulation to encourage the growth of the mushroom fruiting bodies.

Mushroom spawn

Selecting the right spawn for growing lion’s mane mushrooms is super important, folks! The spawn is the “seed” used to inoculate the growing medium or substrate. Choosing the right spawn means you’re on your way to healthy and robust mushroom growth. But if you choose the wrong one, it can be the cause poor yields and contamination – no good!

There are a few different spawn types, like grain spawn, sawdust spawn, and liquid culture. Grain spawn is popular because it’s easy to use with different types of mushroom mycelium.

Once you’ve picked the right spawn, the next step is to mix it with the substrate and let the mycelium do its thing. This period is called the spawn run, and it can take a while, depending on the substrate and environment.

During the spawn run, ensure the temperature and humidity consistently promote optimal mycelium growth. Keeping things clean and preventing contamination is vital since the mycelium is vulnerable to attack from other fungi or bacteria.

Fruiting

Are you ready to grow your lion’s mane mushrooms and become the ultimate fungi farmer? Fantastic! Now let’s discuss creating the perfect environment to get those babies to fruit like nobody’s business!

First off, let’s talk about temperature. You want it to be like a cozy blanket for your mushrooms – not too hot or cold, but just right. Think Goldilocks, but for fungi. We’re talking 60-70°F (15-21°C), folks.

Humidity is also crucial. Think of your lion’s mane mushrooms as being like those diva pop stars who demand humidifiers in their dressing rooms. Keep it between 85-95%, and you’ll be on your way to fame and fortune or at least a tasty and healthy harvest.

Lighting is important too, but don’t go overboard. We’re not trying to give these mushrooms a sunburn! Low-level ambient light is perfect, like mood lighting for your fungi. It’s all about setting the mood for growth.

And let’s remember ventilation! Think of your growing environment like a yoga class – you want good airflow and positive vibes. Use a fan or open a window to keep things fresh and prevent excess moisture from building up.

Quick tip: 

A humidity tent can help create the ideal growing conditions for your lion’s mane mushrooms. Place a clear plastic bag or container over your growing area to trap moisture and create a humid environment.

Remember to poke a few small holes in the bag or container to provide adequate airflow and prevent excess moisture buildup, which can lead to mold growth. Monitor the humidity levels and adjust the airflow to create the perfect growing environment for your lion’s mane mushrooms.

Harvesting & Storage
