King Oyster Mushrooms (Pleurotus Eryngii)

Pleurotus eryngii, commonly referred to as King Oyster mushroom, is a highly regarded edible mushroom species cultivated worldwide. It boasts several common names including King Trumpet and King Brown, though it is universally referred to as "King" due to its prized culinary attributes. Widely considered one of the most flavorful mushrooms, the King Oyster is a favorite among professional chefs and home cooks alike. Its rich, earthy notes make it a staple crop for commercial mushroom farmers. 

Successful cultivation requires precise environmental conditions. The King Oyster thrives at temperatures below 21°C with high ambient humidity levels. Compared to other mushroom varieties, it necessitates tighter controls over factors like temperature, moisture, and airflow to reliably initiate pinning and produce consistent, bountiful yields. Those who master its cultivation are rewarded with a premium mushroom admired by foodies globally.

 

  • Incubation period: 21 days (depends on substrate).
  • Incubation temperature: Room temperature between 21 - 24°C. Do not let the substrate temperature exceed 30°C.
  • Pinning temperature: 10 - 15°C 
  • Pinning humidity: 95 - 100% relative humidity
  • Fruiting temperature:
    • Range: 15 - 21°C
    • Ideal: 15 - 17°C
  • Fruiting humidity: 85 - 90% relative humidity
  • CO2 concentration: 500 - 2000 ppm. Low levels of CO2 will form larger caps and shorter stems. If growing for large stems, increase CO2 levels.

What's Included in Your Mushroom Kit

Please take a moment to review the included items in your mushroom kit. If you have any other questions, our team is happy to assist further. 

The kit contains:

  • Mushroom Substrate Bag: This bag is pre-filled with the grain substrate on the bottom portion.
  • Mushroom Spore Syringe: A sterile syringe containing the mushroom spore liquid culture solution and needle for inoculation.  

Inoculation and Incubation Process

  1. First, use the provided sterile wipe to sanitize the area of the substrate bag where you will inject the liquid culture solution. This injection point should be located at the bottom grain portion. 
  2. Next, insert the syringe needle. Use a lighter or gas stove flame to sterilize the needle until it turns red hot, then allow it to fully cool. 
  3. Once cooled, use the syringe to inject the liquid culture directly into the grains through the substrate bag wall at the sterilized injection point. You only need the very tip of the needle inserted. 
  4. After inoculating, apply sterile tape over the needle hole for containment. Your substrate bag has now been successfully inoculated with the mushroom liquid culture.
  5. Store the inoculated bag in a dry, dark location with an average temperature of 24°C, such as a cabinet or drawer. Check back within 1-2 weeks to ensure full colonization of the grains, which will appear white. 
  6. Once fully colonized, gently mix the substrate and grains by hand-shaking the bag, being careful not to damage the sealed top. Return it to the storage conditions for an additional 2 weeks. 

Tip: Most Mushroom Substrate bags should be white. some mushroom strains (like Lion's mane) sometimes do not look like they are fully colonised, but as long as the bag feels firm your Mushroom Substrate bag is ok.
