THE HASSLE FREE, READY TO SPAWN SOLUTION TO GROWING ELM OYSTER AT HOME
With tall stems and broad, open caps, Elm Oyster mushrooms stand out for their smooth white colour and graceful form. Their flavour is mild, nutty, and slightly earthy, making them a favourite for cooks who prefer mushrooms that enhance rather than overpower a dish.
They grow naturally on elm, maple, and other hardwood trees in parts of Europe and North America, and for many years have been a familiar addition to home-style cooking. Unlike some showier mushrooms, their appeal has always been in their reliability and versatility in the kitchen.
Nutritionally, they’re light on calories and fat, while offering a good boost of protein and fibre (1). Studies are beginning to look into their antioxidant potential and beta-glucans, compounds linked with supporting the body’s natural defences and general wellness (2, 3).
In cooking, Elm Oysters bring a firm bite and a subtle, woodsy aroma that works beautifully in everything from pasta sauces and risottos to soups and sautés. Since they’re a fast-growing species, they’re also a rewarding choice for beginners who want to try their hand at cultivating mushrooms at home.

Whether you’re a seasoned grower or a complete beginner, our spawn takes the guesswork out of mushroom cultivation and turns it into a fun, straightforward process.

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 Elm 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 20–24°C (68–75°F) for optimal mycelium growth.
-
Fruiting: 15-21°C (59-70°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.
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 Elm 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 Elm Oyster liquid culture, the substrate providing the perfect nutrient rich environment for mycelium, promoting rapid colonisation, large yields and minimal risk of contamination.
