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.

Unlock maximum potential in your mushroom cultivation with our professional-grade 2-lb of rye berry mushroom substrate spawn bags with injection ports. Designed for hobbyists and small-scale farms alike, these bags arrive fully sterilized and ready to inoculate — no prep needed. Each bag contains premium organic rye berries that have been hydrated with filtered water and fortified with food-grade calcium and sulfur to deliver superior nutrition and optimal moisture for fast colonization.

Our process is built around performance: we boil each batch of rye berries to the perfect hydration level—firm but pliable—then seal and sterilize each bag to ensure a contamination-free environment. This means when you receive your sterile rye berry spawn bag ready to inoculate, you’re able to focus on growing, not cleaning or prepping. 

Bag features a robust self-healing injection port for safe and efficient inoculation, and a high-quality 0.5-micron gas-exchange filter patch that allows for clean airflow while blocking contaminants. These features make our rye berry mushroom spawn bags with filter patch and injection port among the most user-friendly on the market. Whether you’re using a spore syringe or liquid culture, the process is simple: inject roughly 3cc, shake and massage the bag to distribute the culture, then incubate in the ideal temperature range for your target species.

The nutrient profile of rye berries supports fast, even mycelial growth across a range of gourmet and medicinal mushrooms — from oysters and shiitake to lion’s mane and reishi. With a 2-lb rye berry substrate bag you’re getting enough volume to mix into bulk substrates or fruit directly depending on your workflow. The vacuum-sealed packaging preserves freshness and shelf life, while the double heat-sealed bag protects against punctures and shipping stress, ensuring your spawn arrives in optimal condition.

How to use:

  1. Sanitize your workspace and the bag’s exterior.
  2. Inject approx. 3cc of your preferred spore or liquid culture into the injection port.
  3. Immediately massage and shake the bag gently to distribute inoculant throughout the rye berries.
  4. Incubate at the correct temperature range for your species until full colonization is observed.
  5. When colonization is complete, use the bag as spawn to inoculate bulk substrate or fruit directly. (Spores not included.)
