Known as ‘Lion’s Mane’, the Latin name of the Hericium Erinaceus translates closer to the name ‘bearded hedgehog’. Best known for its beneficial effects on mental health, its long white spikes are iconic in the mushroom world. You can begin growing from the second your order arrives, as all our fresh spawn arrives ready for inoculation.

All our spawn boasts a very low generational count. The lower the generation of the spawn, the nearer to the original spore sample, so at only the fourth generation, Urban Farm-It can promise you the best. Lion’s Mane is best cultivated on logs, so when you enter the world of natural process growing, it is key to have high-quality spawn that you can depend on.

  • Suitable for all customers from hobbyists to professionals
  • A great first time grow, perfect for those in starting out with growing edible mushrooms
  • Will bring harvests of mushrooms, year after year
