Grain Spawn
Preparing your own grain spawn


Grain spawn is a specialized form of mushroom mycelium that is cultivated on whole oats or millet grains, making it an excellent choice for inoculating sterilized or pasteurized substrates. This method is not only effective for small-scale growers but has also become the industry standard for high-volume commercial production. By utilizing grain spawn, cultivators can ensure consistent and reliable mushroom yields. It is important to note that for optimal results, grain spawn should ideally be used within one to two months of being fully inoculated. This time frame helps to maintain the vitality and vigor of the mycelium, ensuring a successful mushroom cultivation experience.
