Our King Oyster (Pleurotus eryngii) liquid culture is a pure, high-yielding strain of live mycelium suspended in a nutrient-rich medium.  

Our liquid culture syringe contains pre-germinated spores, in the form of a liquid mycelium mixture. Liquid cultures are superior to spores as you skip the germination process, allowing for faster colonisation, less contamination and consistent genetic traits. Every batch of our liquid culture is tested on agar, to ensure you receive only the cleanest King Oyster liquid mycelium possible.  

🍄 Live mycelium ready to inoculate grow kits, grains and substrates  

⚡ Enjoy fast colonisation times with our rapidly growing mycelium  

🔬 Lab tested on agar to ensure a clean, healthy culture  

🗓️ Colonise spawn or substrates quickly within 2 weeks   

🛡️ Guaranteed to produce mushrooms or we’ll replace your culture free of charge

Description

FAST COLONISING, HIGH-YIELDING KING OYSTER GENETICS IN LIQUID FORM 

King Oyster mushrooms have a rich culinary tradition in Asia, where they are valued for their satisfying, meaty texture and adaptability in classic dishes. They were first grown in the Mediterranean and then spread across East Asia (1). These mushrooms are popular in many different cuisines because they are a high source of fibre and protein, as well as being totally delicious to eat!  

King Oyster mushrooms are now well-known for their deep, umami taste. Researchers are also studying these mushrooms for compounds like ergothioneine and beta-glucans, which may have antioxidant properties (2). King Oysters also provide fibre and B vitamins, and they are a source of minerals such as potassium, calcium, iron and zinc (3).  

Their versatility makes them ideal for grilling, roasting or slicing into meaty “scallops” for plant-based dishes. The satisfying texture and flavour of King Oyster add dimension to many kinds of dishes, from hearty stews to gourmet meals. They have become a favourite for anyone looking to incorporate a little umami into their cooking.  

Through extensive research and development, we've fine-tuned a unique blend of malt and yeast extracts that give your mycelium the perfect balance of protein and carbohydrates that it needs to grow. Ultimately, promoting healthy growth and rapid colonisation. 

Our liquid cultures are crafted in our lab using pure mushroom cultures from our own commercial master cultures. We guarantee that every culture is 100% contaminant-free and rigorously tested to ensure the health and quality of every strain. 

THE BENEFITS 

  • Grow faster and skip the 1 to 4 week spore germination period 

  • Start with a high-quality, proven strain instead of gambling on the random genetics of a multi-spore syringe 

  • Easy to use, simply inject the culture directly into your sterilised spawn or substrate for immediate colonisation. 

  • Specially selected strains optimised for high yield, nutrient density and flavour 

  • Guaranteed to produce mushrooms or we’ll replace your culture free of charge   

  • Save money by growing your own mushrooms at home  

  • King Oyster mushroom is packed with bioactive compounds like beta glucan   

HOW TO USE 

The process is simple:   

1. Preparation: Take your culture syringe and shake it vigorously for 10 seconds. Unscrew the syringe cap. Fit the sterile needle onto the syringe.  

2. Inoculation: Inoculate your grain spawn or substrate with 5ml of liquid culture via the injection port and leave it to colonise.  

3. Colonisation: Within 3 to 4 weeks, the grain or substrate will colonise fully and be ready to spawn to bulk or fruit. 

GROWING CONDITIONS 

Substrate: Hardwood or 50/50 blend of hardwood and soy hulls (Masters Mix) hydrated to around 60%.  

Temperature: 

  • Colonisation: Around 25°C (77°F) for optimal mycelium growth.    

  • Fruiting: 16-21°C (61-70°F) to encourage primordia formation. 

Humidity: High humidity (over 80%) is essential for healthy, large fruits. Use misting, humidifiers, or a fruiting chamber to maintain humidity.  

Light: 

  • Colonisation: Complete darkness is preferred for rapid colonisation.  

  • Fruiting: Indirect sunlight or ambient light is sufficient. 

Fresh Air Exchange (FAE): Proper ventilation is necessary to provide the growing mushrooms with fresh air and prevent the buildup of carbon dioxide, which can inhibit growth.    

Sterility: Maintaining a clean and sterile environment is paramount to prevent contamination from other fungi or bacteria, which can compete with the mycelium and hinder its growth. 

WHAT’S INCLUDED 

  • Clean King Oyster Liquid mycelium in a 10ml sterile sealed syringe 

  • Sterile 16G x 1.5″ needle and 70% IPA alcohol swab  

STORAGE 

For long-term storage, keep liquid culture syringes in a dark place and preferably in a fridge at 2 to 8°C. They will last up to a year or more if stored correctly. Only certain tropical species like the Pink Oyster should be stored at room temperature.
