Species Profile

Reishi (Ganoderma multipileum) is a slow growing woody mushroom that produces dense colourful antlers or conks. This is a very low maintenance species that prefers temperatures between 20oC and 26oC.

For antler formation, they are best grown inside a sealed filter bag on nutrified sawdust. This variety does not form conks.


Our wholesale grain spawn comes in increments of 10 x 1kg. Each bag of grain spawn is grown using mycelium cultures in our lab. We use sterilized organic rye grain sourced from the Canadian prairies through Grainworks.

We make your spawn to order. We incubate your freshly made spawn between 2-4 weeks to ensure it is strong and healthy. We then ship via Canada Post or notify you for pickup.


Grain spawn must be mixed
with a bulk substrate to fruit mushrooms.

We recommend:

Experienced growers: Use this spawn to inoculate sterilized nutrified sawdust in filter bags. under sterile conditions. At a 10% inoculation rate, 1 bag of grain spawn (1kg) will inoculate about 10 to 12 14A Unicorn filter bags of sterilized substrate.


If you are new to growing, we highly recommend you take a workshop or buy a book on mushroom cultivation.

Care information

If you do not plan to use your spawn immediately, store it in a clean, undisturbed corner of your fridge for up to 6 weeks.
