Collection: Grain Spawn

These pre-inoculated grain spawn bags are inoculated with Rhizo Funga aerated liquid cultures using local and organic grains. Ideal for bulk substrate inoculation or expansion, each Unicorn 4T bag is sterilized, sealed, and inoculated in sterile lab conditions. Whether you're growing oysters, lion’s mane, or other species, our grain spawn delivers strong colonization and guaranteed to be contamination free upon delivery. Grain spawn is typically created after isolating clean mycelium on agar — see our agar tek guide for step-by-step instructions.

Our liquid cultures are crafted under the same verified sterile protocols detailed in our guide, What Really Makes the Best Liquid Culture. Each strain begins with carefully isolated genetics, selected for strength, consistency, and high-yield performance.

Every culture is expanded in a controlled, sterile environment using balanced nutrient media to support clear growth and reliable transfers. This ensures rapid colonization, strong fruiting potential, and reduced contamination risk across species. Cultures are stored cold to preserve vigor and shelf life, ready to perform when you are.

Whether you’re growing gourmet mushrooms at home or running a scaled operation, Rhizo Funga liquid cultures provide a dependable, science-backed foundation for success. Once your culture arrives, prepare clean, nutrient-rich agar plates as your next step toward healthy, repeatable growth.
