Unboxed Organic Rye Berries - used by professional growers in the mushroom industry to grow all varieties of mushrooms.

Premium Sterilized Organic Rye Grain is the top choice for grain spawn in the mushroom industry, and you deserve no less. Rye grain is compatible with most mushroom species because of its high nutrient content, enhanced water retention capabilities, and smaller grain size. Our rye grain is 100% organic, non-GMO and locally sourced. With Myterra Labs, you can expect perfectly hydrated and contamination-free grains, ready for inoculation. Each bag contains an adhesive injection port for sterile inoculations by liquid culture or spore syringe.
