"Blank" Sterile Grains

Blank Sterile Grain Spawn

Our pre-sterilized grain spawn bags provide a clean, nutrient-rich foundation for growing vigorous mycelium. Designed for growers who prefer to inoculate with their own cultures, these grain bags ensure reliable colonization with minimal risk of contamination. Simply introduce your preferred liquid culture or agar wedge under sterile conditions, incubate, and expand as needed.

Each bag is prepared with high-quality grains for optimal hydration and nutrient balance, promoting strong, even colonization.

Ideal for:

• Experienced growers expanding their own strains
• Farms scaling up with consistent, sterile grain spawn
• Mycology researchers and cultivators experimenting with different cultures

Made to order: Please allow 1 week for production and shipping.
