Agar Cultivation

  1. Prepare the agar medium by mixing water, agar powder, and nutrients such as malt extract or potato dextrose agar in a flask.
  2. Autoclave the agar medium to sterilize it and let it cool to around 50°C.
  3. In a sterile environment, pour the agar medium into petri dishes to create a solid surface for the mushroom mycelium to grow on.
  4. Using a sterile technique, transfer a small piece of healthy lion's mane mushroom tissue onto the agar surface.
  5. Seal the petri dishes with parafilm or tape to prevent contamination and store them in a warm, dark place to encourage mycelium growth.
  6. Check the petri dishes regularly for signs of contamination or growth of the lion's mane mycelium.
  7. Once the mycelium has fully colonized the agar plates, you can use it to inoculate substrate for fruiting the lion's mane mushrooms.

Liquid Culture Cultivation

  1. Prepare a sterile work area by wiping down all surfaces with a disinfectant such as isopropyl alcohol.
  2. Gather your supplies, including a spore syringe or liquid culture syringe, a sterile syringe, a pressure cooker, and a clean glass jar.
  3. Fill the glass jar with sterilized water and add a small amount of light malt extract or another sugar source to provide nutrients for the mycelium.
  4. Using a flame-sterilized needle, inject the spore or liquid culture syringe into the jar of nutrient solution.
  5. Place the jar in a warm, dark area and allow the mycelium to grow and colonize the liquid culture. This process can take several weeks.
  6. Check the jar regularly for signs of contamination, such as mold growth or off smells. If contamination is present, discard the liquid culture and start over.
  7. Once the liquid culture is fully colonized with mycelium, it is ready to be used to inoculate your substrate for growing lions mane mushrooms.

Grain Spawn Prep and Innoculation

  1. Prepare your grain substrate, such as rye or millet, by rinsing it thoroughly and soaking it overnight.
  2. Drain the soaked grains and fill your jars or bags with the substrate, leaving some space at the top for shaking.
  3. Sterilize the substrate by pressure cooking at 15 psi for 90 minutes to kill any competing organisms.
  4. Allow the substrate to cool completely before inoculation to prevent contamination.
  5. Inoculate the cooled substrate with lion's mane mushroom spawn using a sterile technique, such as a flow hood or glove box.
  6. Shake the jars or bags to evenly distribute the spawn throughout the substrate.
  7. Incubate the inoculated grain spawn in a warm, dark place for 2-4 weeks, or until fully colonized with mycelium.
  8. Once fully colonized, the grain spawn is ready to be used to inoculate your fruiting substrate for growing lion's mane mushrooms.
