Product Overview

Product Overview

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 an iconic sight to the mushroom world. You can begin growing from the second your order arrives, as all our fresh spawn arrives ready for inoculation. 

When growing Lions Mane from grain spawn, it is essential to sterilise the substrate beforehand. There are plenty of resources online and on our website to aid you with this step. We also guarantee fast and responsive customer aftercare every step of the way, so feel free to drop us a message.

All of 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. It is also double tested and axenic, meaning it is not just the best but dependable as well. 

  • Suitable for all customers from hobbyists to professionals
  • A great first time grow, perfect for those in starting out with growing edible mushrooms
  • Offers up to three flushes

Product Description

Product Description

Lion’s Mane is most recognisable for its long, white, cascading, spine like fruiting body. It is a great place to start if you are venturing beyond the traditional oyster mushroom grow. Whether you are growing on a commercial scale, or from your own back garden, we recommend eating it fried up with garlic and butter. 

Using grain spawn offers you a quicker harvest as compared to less intensive methods, such as log grows. It will thrive on more woody substrates, such as straw. All our spawn is stored in specialist breathable Microsac bags. This means that the spawn is always at its freshest, from our fridges to yours.

  • Suitable for all customers, from hobbyists to professionals
  • Unusual fruiting body which offers a new growing experience 
  • Can bring flush after flush for up to eight years
