Create your own grain spawn with our Sterilized Millet Grain Bag. Why choose millet over other grains? Millet offers small kernels that create more inoculation points, boosting colonization speed and fostering strong mycelial growth.

Each bag is equipped with a self-healing injection port, allowing for easy inoculation with a liquid culture syringe. This feature minimizes contamination risks and streamlines the process, making it accessible for both beginners and seasoned cultivators.


To inoculate a sterilized grain bag with mycelium, you'll need a liquid culture syringe.

We recommend performing inoculation in a still air box or laminar flow hood to reduce the possibility of contamination. However, it's still possible to get good results without these tools—cleaning your working space, tools and materials with isopropyl alcohol is key.

Always handle liquid culture syringes using sterile technique, ensuring they are thoroughly shaken before use. Flame sterilize the needle (a regular lighter works fine), let it briefly cool down, then insert it into the grain bag's self-healing injection port. Inject 3-5 ml of liquid culture per 1.5 kg grain bag. If you intend to reuse your needle, sterilize it before and after each subsequent use.

For a visual demonstration of this technique, watch the video below.

Store grain bags in a cool, dark place at room temperature. You don't need to refrigerate them, and they can be kept for several months until you're ready to use them.
