North Spore Organic (3 lbs) Sterilized Hydrated Grain Bag w/Self-Healing Injection Port | Sterile Mushroom Spawn Bag w/ 0.2 Micron Filter Patch | USDA Certified Organic

Our premium organic sterilized grain bag was formulated by mycologists to maximize the speed and size of your mushroom grow. Each spawn bag contains our proprietary 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.) MIXING WITH SUBSTRATE We recommended 1 lb of colonized grain spawn for every 5 lb of manure or hardwood substrate. INOCULATION To inoculate the grain bag, simply inject your spore or culture syringe through the port in a sterile location. We always recommend clean hands and latex gloves to reduce the introduction of contaminants. (It is best practice to wait a minimum of 1 week after arrival before injecting grain bags to ensure they were not compromised during transit.) COLONIZATION Allow your bag to colonize in a cool location out of direct sunlight. The temperature for incubation shouldn't exceed 75 degrees F or dip below 55 degrees F. After a couple of weeks, you should start to see mycelium growing on the grain. You'll notice the white mycelium growing outward from the injection point. When it has grown three to four inches you should, without opening the bag, carefully break up the colonized grain and mix it into the uncolonized grain. This will dramatically speed up the colonization process. When the bag is completely white with mycelium your spawn is ready to use. This may take a couple of weeks to a month or more depending on the species and vigor of your culture. STORING Grain bags should be stored at room temperature out of direct sunlight. No refrigeration is necessary. They can also be stored for several months before use. STERILIZATION Our grain spawn bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.
