Wheat Berry Mushroom Spawn Bags (4 lb)

Unlock the power of clean, professional-grade mushroom spawn with our 2-pack wheat berry spawn bags with injection port and 0.5-micron filter patch — ideal for hobbyists and small-scale cultivators seeking high-performance substrate ready to go. Each order includes two pre-sterilized bags of hydrated white wheat berries, fortified with gypsum and packaged under clean-room conditions to deliver exceptional cleanliness and consistency. Shroomability

Our wheat berries are carefully hydrated using filtered water and food-grade additives to ensure optimal moisture content and kernel integrity — ready to support vigorous mycelial growth. The bags are fully sterilized, double-sealed, and include both a self-healing inoculation port and a 0.5-micron gas exchange filter patch for safe, efficient inoculation and colonization. Shroomability

Why choose wheat berry substrate and our dual-bag format?

Wheat berries are a versatile, nutrient-rich grain that supports a wide range of gourmet and medicinal mushroom species. Their firm structure and excellent moisture retention make them ideal for clean mycelial colonization, with fewer issues like moisture pooling or kernel collapse. With this 2-bag format, you’re equipped for small-batch runs, backup bags, or scaling experiments without investing in bulk equipment. Each bag works straight out of the box.

Ready-to-use design for simplified cultivation

Say goodbye to jar prep, pressure-cooking, and grain-soaking headaches. Our wheat berry spawn bags ready to inoculate arrive sterilized and sealed; simply inject, shake, incubate. The self-healing injection port lets you introduce your favorite spore solution or liquid culture with minimal contamination risk. The 0.5-micron filter patch delivers ideal gas exchange — allowing CO₂ to escape while keeping contaminants out.

How to use:

1. Clean your workspace and sanitize the bag exterior.

2. Inject ~3 cc of your spore solution or liquid culture through the injection port.

3. Gently massage and shake the bag to distribute the inoculant throughout the wheat berry matrix.

4. Incubate at your mushroom strain’s optimal temperature (for example, 70-78 °F) until colonization is complete. Shroomability

5. Once fully colonized, you may use the bag as spawn to mix into bulk substrate or fruit directly depending on your workflow. (Spores not included.)
