Collection: Sterilised Grain Bags

Our sterilised grain bags are ready to inoculate, so you can skip the soaking, filling and pressure cooking. Use them as grain spawn for your liquid culture or spore syringe, then spread the colonised grain into your substrate. Perfect for growers who want reliable grain spawn without the sterilisation work.

Choose the grain that fits your goal. Rye grain bags are ideal for high yield. Millet grain bags offer the highest colonisation speed. Milo grain bags are the balanced option between speed and yield.
