Mixed Seed Grain Spawn

Our premium mixed seed grain spawn is meticulously prepared to give your mushroom cultivation the best possible foundation. Each batch begins with a careful 24-hour soak in our double-filtered water, ensuring optimal hydration and nutrient absorption from the start. The grains are then gently simmered to activate their structure and improve colonisation rates, followed by thorough sterilisation in our professional-grade autoclaves. This multi-stage process eliminates competing organisms and contaminants, creating a clean, reliable substrate that's ready to inoculate. Whether you're cultivating oyster, shiitake, or specialty varieties, our mixed grain blend provides excellent nutrition and colonisation speed. The result is vigorous mycelium growth and healthier fruiting bodies, giving you confidence in every cultivation cycle.
