3lb Sterilized Grain Bag by Microvora

Each contains 3 pounds of hydrated rye grains. The rye is washed thoroughly then soaked for 16-24 hours before being boiled. It’s then drained and set on racks to air dry. The rye is measured out into 3 pound bags and pressure sterilized before being sealed and shipped to you. These rye bags are ideal for growing spawn on! Inoculate with 10CC of liquid culture and within two-three weeks they will be fully colonized and ready to mix with bulk substrate.
