North Spore grain spawn is USDA Certified Organic and produced in our vertically-integrated facility located in Westbrook, Maine. Production is overseen by a team of expert mycologists, lab technicians, and seasoned mushroom spawn production specialists. We start the process by taking mushroom cultures from our own culture bank and growing them out on a blend of sterilized millet and wheat berries. And many of our cultures were isolated and grown from wild mushrooms foraged in New England.
A proprietary blend of sterilized organic grains, including millet and wheat berries.
North Spore now offers insulated shipping for online grain spawn orders. Our insulated shippers fit up to 4 bags of spawn each, and we charge a flat rate of $30 for the first shipper and $15 for each additional shipper, plus normal shipping costs. This covers the insulated shipper itself, the ice packs we use to keep the spawn cool, and extra shipping costs that result from the added weight of the ice packs. We recommend using insulated shippers as long as daytime temperatures in your area are above 80 degrees. We guarantee that spawn shipped using our insulated shippers will arrive healthy and viable.
Because spawn can still become jostled in shipping, we recommend letting the bags sit at room temperature for 48 hours after receiving before refrigerating again.
