Lion’s Mane has been cultivated and consumed in Asia for thousands of years and is traditionally associated with cognitive wellbeing and mental clarity. Historical accounts describe its use by Buddhist monks, who valued it for supporting focus during meditation.
Today, Lion’s Mane is widely studied for its potential cognitive-supporting properties. Research has identified naturally occurring compounds such as hericenones and erinacines, which are associated with Nerve Growth Factor (NGF) activity — a molecule involved in the maintenance and development of neurons.
In addition to its potential cognitive benefits, Lion’s Mane is a highly versatile culinary mushroom. It can be cooked fresh, dried, extracted, or brewed as a tea. When cooked, its texture and flavour are often compared to crab or lobster, making it a popular plant-based alternative to seafood.
Growing your own Lion’s Mane mushrooms at home is simple with this Lion’s Mane Mushroom Grain Spawn, produced by our trusted partners at Martian Mushrooms. Suitable for beginners and experienced growers alike, this spawn is designed to make cultivation straightforward and reliable.
The grain spawn arrives pre-colonised and ready to mix with your chosen substrate — no inoculation or waiting for grain to colonise. With the right conditions, you can expect thick, dense clusters of Lion’s Mane mushrooms, ready to cook, dry or extract.

Cut the top of the bag just below the seal to expose the block to fresh air. Mist once or twice daily.
Side Fruiting (Optional)
Alternatively, cut a small “X” in the side of the bag and mist the opening at least twice daily.
Fruiting Environment
For best results, place the block in a fruiting chamber such as a MonoTub or Martha tent to help maintain ideal humidity and airflow.
