Canadian Grown & Made
Produced in a CFIA-licensed facility in Ontario, Canada
Lion's Mane (Hericium erinaceus) is one of the most sought-after mushrooms in North America, valued equally for its remarkable health benefits and its unique culinary profile. Often described as tasting like lobster or crab when seared, Lion's Mane has become a premium product at farmers markets, health food stores, and restaurants across Canada. With growing consumer awareness of its brain-health and nervous system benefits, demand consistently outpaces supply.
Each 5 lb bag contains fully colonized organic millet grain spawn produced in-house at our CFIA-licensed facility in Brantford, Ontario. Our Lion's Mane genetics are lab-tested for purity, vigour, and fruiting performance. Sterile production practices from start to finish ensure you receive clean, reliable spawn for commercial or home cultivation.
Lion's Mane performs best on supplemented hardwood sawdust or masters mix (50/50 hardwood sawdust and soy hull pellets). Mix grain spawn at a 10–15% rate, pack into grow bags, and colonize at 21–24°C. Once fully colonized, cut small openings in the bag and introduce fruiting conditions. Lion's Mane fruits from the openings as a single large mass or several smaller clusters, depending on the number of cuts.

Excellent lion's mane spawn bag! Very vigorous mycelium growth. Used it to inoculate hardwood sawdust and got beautiful fruits. Nature Lion spawn is the gold standard.
