Experience reliable mushroom cultivation with Mycelium’s sterile milo grain spawn bags, offered in both 3 lb and 5 lb sizes.

Its small grain size increases surface area, supporting fast and uniform colonization. Each bag comes fully sterilized, with a self-healing injection port and a .2-micron filter patch for optimal airflow and contamination protection. Ideal for growing Lion’s Mane, Oyster, Shiitake, Turkey Tail, and Reishi mushrooms. Just add liquid culture and watch your mycelium thrive. (Liquid culture sold separately.)
