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

#ad
North Spore #ad - If you have any issues or questions, just reach out to us. This will dramatically speed up the colonization process. For better results: when the mycelium 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.

Self-healing injection port: bags include a self-healing injection port for use with a spore or culture syringe plus a 02 micron filter patch to block airborne contaminants while providing even gas exchange. We want your grow to be a success! Colonization: allow your bag to colonize in a cool location out of direct sunlight. Optimal moisture content: without moisture, mycelium will not colonize.

They can also be stored for several months before use. The temperature for incubation shouldn't exceed 75 degrees F or dip below 55 degrees F. When the bag is completely white with mycelium your spawn is ready to use. Mixing with substrate: we recommended 1 lb of colonized grain spawn for every 5 lb of manure or hardwood substrate. We also recommend using 2. 5-5ccs per 3 lb grain bag. All of our grain spawn bags are hydrated to a target of 50%.
