Product Details
Big Balls is our Lion's Mane strain (Hericium erinaceus), supplied here as fully colonized grain spawn, 5 lb bag. Every culture is produced fresh in-house at our CFIA-licensed facility in Brantford, Ontario.
Grain spawn arrives fully colonized and ready to run: mix into pasteurized substrate, bulk containers, or outdoor beds depending on the species. Produced fresh to order — expect our standard fresh-to-order lead time before shipping.
Multiple strains of the same species share their common and scientific name — what makes this one different is the strain itself. Big Balls is maintained in our culture library and verified clean before anything leaves the lab.
