Our Mushroom Spawn Range

Lion's Mane Mushroom Plug Spawn


Lion's mane mushrooms (Hericium erinaceus) are cultivated using the plug spawn method, which involves inoculating hardwood logs, such as oak or beech, with mushroom plugs. This method allows the fungi to grow slowly over several months to years, mimicking their natural environment. The logs are drilled, filled with the spawn, and sealed with wax to maintain moisture and protect from contaminants. Optimal conditions for growth include shaded, humid environments with temperatures between 55-75°F (13-24°C). 

Shiitake Mushroom Plug Spawn

Shiitake mushrooms (Lentinula edodes) are one of the most popular edible mushrooms worldwide. They are commonly grown on hardwood logs using plug spawn, which allows for easy inoculation. Shiitake mushrooms have a rich, umami flavor and are often used in Asian cuisine. Their cultivation process typically requires patience, as shiitake mushrooms can take several months to fruit after inoculation​. Once established, these mushrooms can produce multiple flushes, making them a sustainable and rewarding crop for both home growers and commercial producers.

Live Portobello Mushroom Spawn (Agaricus Bisporus)

Portobello mushrooms are one of the most popular edible mushrooms worldwide, recognized for their meaty texture and rich, earthy flavor. They are widely cultivated and can be grown on a large scale. Our Portobello Mushroom Grain Spawn is grown on certified organic rye berries and is ready to inoculate bulk substrate quickly. Ideal for medium and large-scale growers, this spawn can be transferred to bulk substrate bags using a flow-hood or bio-cabinet. Portobello mushrooms are often used in grilling, sautéing, or stuffed as a meat substitute due to their substantial texture and umami flavor.

Wine Cap Mushroom Grain Spawn (Stropharia rugoso-annulata)

Our Wine Cap mushrooms, also known as "Garden Giants," are perfect for beginners. They are known for their ease of cultivation and their mild, earthy flavor that pairs well with artichokes and potatoes. Wine Cap mushrooms can be grown on hardwood chips or straw beds, and they colonize quickly, producing reliable flushes for several years. This makes them an excellent option for beginners. The mushrooms feature port-wine-colored caps and white stalks, which are great for braising, sautéing, grilling, or pickling. Plant in partially shaded areas to reduce the need for watering, and add fresh woody material each year to maintain the health of the bed. Sawdust spawn can be used for quicker fruiting in the first year.

Growing Essential 

PVC Mushroom Spawn Grow Bag

Our PVC Mushroom Spawn Grow Bag is made from long-lasting, high-temperature-resistant polypropylene. It is designed for efficient mushroom cultivation and measures 5" x 20". It features a square gusset to increase mushroom yield and an air vent window (0.2um aperture) for proper gas exchange without contamination. The pre-sealable design reduces labor and shortens the mycelial fermentation cycle, making it ideal for both amateur and commercial mushroom growers.

How To Take Care Of Mushroom Spawns

Taking care of mushroom spawn involves specific storage and handling practices to secure its viability and effectiveness for cultivation. Here are some essential tips that you can incorporate:

Storage Conditions

Store your mushroom spawn in a cool, dark place, ideally between 35°F to 50°F (2°C to 10°C). A refrigerator or a cool basement works well. Avoid freezing, as it can damage the mycelium​.

Humidity

To prevent the spawn from drying out, maintain its humidity levels around 70% to 80%. Use a hygrometer to monitor levels, and consider placing a dish of water or damp cloth in the storage area​.

Ventilation

Maintain a good airflow to prevent mold and bacterial growth while avoiding excessive drafts. Proper ventilation helps keep the environment conducive for spawn longevity.​

Contamination Prevention

Always sanitize your hands before handling the spawn, and use clean, sterile tools and containers. Seal storage containers tightly to keep out airborne contaminants​.

Regular Inspection 

Regularly check the spawn for any signs of contamination, such as mold or unusual textures, and dispose of any affected portions immediately​.

Labelling and Organization

Clearly label storage containers with details like species, strain, and storage date to manage your supplies efficiently.

FAQ’s

Q1: How do I choose the right mushroom spawn for my needs?

Choosing the right mushroom spawn depends on factors like your growing conditions, the mushroom species you want to cultivate, and the substrate available. For beginners, easy-to-grow varieties like oysters or shiitake mushrooms are recommended. Additionally, consider the growing environment—indoors, outdoors, or in controlled settings​

Q2: What is a mushroom grain spawn?

Mushroom grain spawn refers to a substrate (like rye or millet grains) that has been colonized by mushroom mycelium. It’s commonly used in commercial and home cultivation as a medium to introduce mycelium to bulk substrates like straw or sawdust, which then grow into fruiting mushrooms​

Q3: Can mushroom spawn be frozen?

Mushroom spawn should not be frozen. Freezing damages the mycelium and can result in a loss of viability. It’s best to refrigerate it as freezing leads to cell wall rupture, killing the delicate mycelium.
