Mushroom Grain Spawn


Mushroom spawn is the basis for growing and expanding your mushroom production! It is essentially any sort of material also known as substrate, in which the mycelial tissue of the fungi can grow on. Each Mushroom Spawn is colonized by a specialty mushroom mycelium and can be spread or inoculated into a new substrate to increase production potential. Spawn can come in different forms, depending on the substrate.



Grain spawn is ideal for inoculating sterilized or pasteurized substrates. It is full of nutrients and a great option for expanding substrates or adding to a lower nutrient substrate, such as straw or sawdust. It is great for high volume production and can be stored for months in a refrigerator.
