THE HASSLE FREE, READY TO SPAWN SOLUTION TO GROWING BLACK PEARL KING OYSTER MUSHROOMS AT HOME
Black Pearl King Oyster mushrooms has roots in East Asian cultivation, where Oyster and King Oyster varieties have been grown and cooked for generations. It is a relatively modern cross, but it carries the same practical appeal that made its parent varieties staples in home kitchens.
Nutritionally, it offers the same general profile associated with Oyster and King Oyster mushrooms. It provides fibre and beta glucans (1), which some research suggests may support normal immune function as part of a balanced diet. It also contains B vitamins and minerals that contribute to everyday nutritional needs (2).
Unlike thinner oyster types, Black Pearl King Oyster mushrooms develop a dense stem and broad cap with a firm bite. When you slice it thick and cook it slowly, the texture becomes layered and almost scallop like. If you score the stem and sear it in a hot pan with a little oil, it browns deeply and keeps its structure. It does not collapse into softness unless you overcook it.

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 sawdust or Masters Mix (50/50 hardwood and soy hulls) for Black Pearl King Oysters.
Top or Side Fruiting: You can cut a small “X” in the side or cut the top of the bag. Unlike regular oysters, these can fruit beautifully from the top to develop their signature thick, meaty stems. 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 the consistent humidity levels these mushrooms prefer.
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: 13–17°C 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 Black Pearl King 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 Black Pearl King Oyster liquid culture, the substrate providing the perfect nutrient rich environment for mycelium, promoting rapid colonisation, large yields and minimal risk of contamination.
