{"title":"Mushroom Grain Spawn","description":"\u003cp\u003eGrain spawn is colonised grain used to seed bulk substrate - the multiplication step that turns a few cc of culture into enough living mycelium to run a tub. Preparing it yourself means hydrating grain, loading filter-patch bags and sterilizing at 15 PSI for 90-120 minutes.

Each 3 lb bag is filled with fully hydrated red milo (sorghum), a nutritious, medium-sized grain that offers excellent moisture retention and an ideal surface area for rapid mycelial growth. This grain spawn is sterilized in a professional lab setting and packaged in a durable Sakato-brand polypropylene bag equipped with a 0.2-micron filter patch for clean gas exchange and a self-healing injection port for easy, contamination-free inoculation using liquid culture or spore syringe. Suitable for growing a variety of mushrooms—both dung-loving and gourmet varieties—this grain bag is perfect for home growers and commercial cultivators alike. For best results, use one 3 lb bag of spawn with a 5 lb substrate bag for dung-loving mushrooms (2:1 ratio), or at least 0.5 lbs per 5 lbs of substrate for gourmet species (10–15% spawn
