Switch sizes without leaving the pageOur Sterilized Grain Spawn Bags are made with a balanced blend of millet and sawdust, pre-sterilized and hydrated to the ideal moisture ratio to support vigorous mycelial expansion. Each 6 lb bag is clean, sealed, and fitted with a filter patch — no injection port included, so you'll simply open the bag from the top for grain spawn inoculation or any application requiring direct access.
Optimized for use in clean environments between 70–78°F, this grain substrate supports a wide variety of mushroom species, delivering fast colonization and vigorous growth for home growers and large-scale cultivators alike.
Every bag is sealed in front of flow hoods, wiped with hospital-grade sterilizers, and stretch-wrapped to prevent contamination or shipping damage. Open the bag, add your culture, and wait for full colonization.
