Sterilized Rye Grain Bag with Injection Port

Presenting our highly sought-after organic grain spawn bags, meticulously crafted to optimize mushroom growth. These bags are enriched with a blend of nutrient-rich organic rye grain, complemented by a self-healing injection port and a 0.2 micron filter patch, ensuring efficient gas exchange while preventing contamination. For optimal results, apply 1 lb of spawn for every 5 lbs of substrate, and for our 3.5 lb bags, use 2.5-5ccs of spawn. Rye was thoughtfully chosen for their exceptional nutritional value and minimal risk of contamination. Rest assured of absolute sterility, as our bags undergo thorough sterilization using a commercial-grade autoclave, providing an unwavering assurance of purity.
