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 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

Product Description

Our Lion’s Mane spawn now comes in plugs, allowing you to inoculate a log stump and replicate woodland environments. Inoculation of a log is a process involving drilling into a log and hammering the spawn dowel into the hole, before sealing with wax. It can take a year to see the fruits of your labour flourish from a log grow, but beyond that a log grow will bring you harvests of mushrooms for up to eight years. Not only does this help you invest in a long-term sustainable food source, but it also makes a gourmet meal at the end – the taste is often compared to lobster!

Reconnecting with natural growing processes, like log grows, offers a fresh and nutrient rich meal in any environment, without the need to go shopping. Log grows also remove the part packaging plays in so many of our meals. In offering you the highest quality, fresh living spawn, we hope you will be able to take away what urban growing could mean for our planet. 

All of our spawn is stored in specialist breathable Microsac bags. This means that the spawn is always at its freshest, from our fridges to yours.

For larger quantities, check out our wholesale collection. 


Growing your own Lions Mane is a straightforward process. We’ve got a further guide on how to inoculate logs on our website, and extensive customer aftercare is always available. 

Log Types: Logs of healthy freshly cut (2 weeks – 10 weeks) hardwoods are most suitable such as Oak and Beech. Avoid coniferous wood types.

Log size: Up to 1.25m long and 10-20cm diameter is ideal (the larger the log the longer to colonisation and the greater the production).

How to inoculate: Use roughly 40-50 plugs per 50cm length (you can speed up colonisation by increasing the density). Use an 8mm drill bit to a depth of 5-6cm and spacing of 10-15cm between holes. Seal with a natural food grade wax to help retain moisture and keep out competing organisms.

When to inoculate: Logs can be plugged anytime although not in frosty conditions is best. Best time to cut is when trees are dormant (winter and early spring).

Fruiting Season: August to December, but as late as February

NOTE: For slower growing species, such as Lions Mane, pasteurisation of the log may be necessary if not totally fresh. For advice on pasteurisation, take a look at our website.
