Eastern civilisations have been using Blue Oyster mushrooms for generations. Historically, they were grown as a staple food source in ancient Japan and prized for their potential nutritional and wellness benefits. 

In recent years, the possible benefits of Blue Oyster mushrooms on cardiovascular health are being investigated. According to scientific research, Blue Oyster mushrooms contain a compound called lovastatin, a natural form of statins that may regulate cholesterol (1). Furthermore, Blue Oyster mushrooms are abundant in polysaccharides and antioxidants, which are being researched for their potential role in promoting immunological function (2). 

Due to their mild, earthy flavour and delicate texture, Blue Oyster mushrooms are highly valued in the culinary world. They are versatile, simple to prepare, and give a distinct depth to a variety of foods, including pasta, stir-fries, risottos, and soups. Their exquisite flavour and texture enhance any dish, and their gratifying meaty character makes them an excellent alternative to traditional proteins.

HOW TO USE 

The process is simple: 

Inoculation: Mix the grain spawn with the substrate at a roughly 6:1 ratio, depending on the specific substrate you’re using. We recommend hardwood or masters mix substrates for Blue Oyster. 

Side Fruiting: You can cut a small “X” or slit in the side of your bag to allow your mushrooms to grow out from the sides of the block. Make sure to spray at least twice a day to keep the cut area moist. 

Humidity-Controlled Chamber: Finally, you can place the fruiting block in a chamber such as a MonoTub or Martha tent for optimal growth, as this will help maintain ideal fruiting conditions. 

Gone are the days of having to trawl through decade-old forum posts to figure out the fascinating but often confusing science that is growing mushrooms. Our step-by-step, easy-to-follow guide ensures a successful harvest, eliminating guesswork and making the whole process a breeze. 

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: 15-20°C (59-68°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.  

INGREDIENTS  

Great mushrooms begin with great spawn. That is why we only use our 100% natural and organic grain in our spawn. We only use high-quality, natural ingredients for our products, specifically selected to support the optimal growth of Blue Oyster mushrooms. 

Our optimally hydrated millet and milo blend is ideal for spawn production because it colonises quickly and resists contamination better than many other grains, including Rye. We first soak and then cook our grain, carefully hydrating it to around 50% water content before sterilising the bags in a computer-controlled steam autoclave for 2 hours at 121°C. 

This is then inoculated with our own Blue Oyster liquid culture, the substrate providing the perfect nutrient rich environment for mycelium, promoting rapid colonisation, large yields and minimal risk of contamination.
