Grain Spawn
Supplying grain spawn for mushroom cultivators and at-home hobbyists is our core business. You choose from more than 20 strains and species or request a custom blend.
Our spawn is made from an organic blend of sorghum and gypsum that is sterilized in a high temp/high pressure autoclave. The 6 pounds of organic grain spawn is contained in a zipper polypropylene bag (Sac 02™).
The large batch production helps growers focus on fruiting the mushrooms.
All grain spawn is G1. To ensure a strong and vigorous strain, we do not expand beyond G1. As a result, our spawn will colonize faster, grow healthier mycelium and produce more robust fruit.
Inoculate your choice of substrate with our grain spawn and you are ready to grow.
For orders of ten or more, call (612) 405-3425.
