Organic sterilized grain spawn bag was formulated by mycologists to maximize the speed and size of your mushroom grow. (All that's required is a spore syringe or liquid culture!)

Each spawn bag contains our proprietary grain blend featuring hydrated, nutrient-rich, organic millet and wheat berries. Bags also include a self-healing injection port for use with a spore or culture syringe plus a 0.2 micron filter patch to block airborne contaminants while providing even gas exchange. Note: Color of injection port may vary.
