Spawn Bag & Jar Tips
Spawn Bag & Jar Tips
After injecting your bag or jar, give it a gentle shake. For bags, make sure any grains stuck in the upper portion are knocked down so they can colonize properly. There’s no need to break up the spawn during colonization unless you prefer to. If you choose to do so, wait until the bag or jar is roughly 50% colonized before mixing.

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. Certified Glyphosate Residue Free Wheat.
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:
-
Clean your workspace and sanitize the bag exterior.
-
Inject ~3 cc of your spore solution or liquid culture through the injection port.
-
Gently massage and shake the bag to distribute the inoculant throughout the wheat berry matrix.
-
Incubate at your mushroom strain’s optimal temperature required for the strain (for example, 70-78 °F) until colonization is complete.
-
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.)
