18 x 1 lb. Sterilized Rye Berries Mushroom Substrate Bags for Grain Spawn

This package contains 18 bags of sterilized rye berries, perfect for mushroom growth. The substrate block is made from high-quality materials and is suitable for use in any region. These bags are ideal for grain spawn and can be used for a variety of mushroom species. The product is made in the United States and adheres to the highest levels of quality and safety standards.

Our 1lb rye berry grain spawn bags are perfect for incubating mushroom mycelium. We use 100% certified organic rye berries perfectly hydrated to the right moisture levels. Our rye berries are supplemented with gypsum and calcium for optimal results. We use the thickest bags available, to ensure the sterility of the block. Inoculation instructions are included.

Note: These bags are cheaper because they do not have injection ports. These are the bags we use, because injection ports are not needed. We inject straight through the plastic and cover the hole with heavy duty scotch tape. Scotch tape is sterile off the roll due to the process it undergoes to lay the adhesive. Do not use micropore tape or a breathable tape, because it will contaminate your substrate.
