Sterile grain spawn for mushroom production mycology products with fil

Guaranteed sterile uncolonized grain spawn for growing mushrooms. Choose 1 myco quart (0.8 lb) or a 3 lb bag, both with an 0.2 micron filter and self-healing injection port (SHIP). Grain choices include oats, popcorn drippy corn, millet, or a custom combination. Add colonized grain, colonized agar, spores, or liquid culture to this grain. Once colonized, add to substrate and grow mushrooms! Please note, I do not sell or distribute for illegal activities. Only the grain is included, no genetics.
