Lion's Mane Mushroom Grain Spawn - UK


The Lion's Mane mushroom produces beautiful white coral-like fruitbodies, with an amazing seafood flavour and meaty texture. 

It is a highly prized medicinal mushroom, which prefers to grow on sterilised supplemented sawdust substrate and is fairly easy to grow.

This spawn pack includes:

  • 2.8kg of quality Lion's Mane mushroom grain spawn
  • 20 x Mushroom cultivation bags (can hold 1.5-2 kg substrate per bag)

Difficulty: Medium 

Lion's Mane is best suited to growers who have a bit of experience. They are fast to colonise and fruit easily, but they preferred a sterilised and supplemented hardwood substrate. This makes them more difficult than Oyster mushrooms which can be grown on a wide variety of pasteurised substrates.

Check out our guide on growing Lion's Mane mushrooms for more info.
