King Oyster mushrooms are a great beginner mushroom and easy to grow. This is a commercial strain that produces large mushrooms with a thick stem and smaller cap.
King oysters are delicious when fried - their meaty texture pairs well with any dish, but absorbs butter and garlic best. We encourage you to experiment with your favorite culinary flavors.
What is a liquid culture?
Liquid cultures are a mixture of mushroom mycelium and a liquid nutrient blend. Liquid culture inoculation of grain is able to be performed in clean areas with very little air movement.
Use this liquid culture on grains, such as Myterra Labs' Organic Rye or Organic Oats. One syringe is able to inoculate 2 bags of grain. This culture can also be used to inoculate agar plates and liquid culture jars to expand the culture.
King Oyster mushrooms will need to be fruited on Myterra Labs Woodlovers substrate. Once your grain is fully colonized by the mycelium, you will have enough spawn to add into 2-8 bags of Woodlovers. Trying to produce mushrooms from grain is very difficult and does not yield as many mushrooms. Once you have added your King Oyster spawn into your Woodlover Bags, seal the bag and shake it to evenly distribute the grains. Do not shake again after this step. Allow the Woodlover bag to colonize and watch as small mushrooms start to form after 1 week. King Oysters produce the best mushrooms when fruited from the top of the substrate, so you will need to cut open the top of the bag once small mushrooms have started to form.
Ensure that you use a sterile technique to inoculate the grain bags: Wipe the outside of the bag or injection port with 70% isopropyl alcohol prior to inoculation and do not allow the syringe tip or needle to touch any items that have not been cleaned with alcohol.
Store excess liquid culture in the fridge with a capped syringe.
King oysters prefer cooler temperatures to fruit, but room temperature is fine for grain inoculation and colonization.
