Sterilized Grain Bag with Injection Port

Organic 2lb Sterilized Millet Grain Spawn Bag

Take the guesswork out of your mushroom cultivation. Our sterilized grain spawn bags provide the perfect, nutrient-rich foundation for your favorite mushroom species. Designed for both beginners and professional mycologists, these bags offer a "set it and forget it" solution for rapid mycelium growth.

Why Millet?

While many growers use rye or wheat, millet is the gold standard for high-performance spawn. Because millet seeds are smaller, they provide significantly more "inoculation points" per pound. This means your mycelium spreads faster and more evenly throughout the bag once shaken.

Key Features

• Contamination-Free Inoculation: Equipped with a heavy-duty Self-Healing Injection Port (SHIP). Inject your spores or liquid culture without ever exposing the sterilized grain to outside air.

• Breathable Design: A integrated 0.3-micron filter patch allows for essential gas exchange while keeping even the microscopic contaminants out.

• Professional Grade Sterilization: Every bag is hydrated to the perfect moisture content and processed in a commercial-grade autoclave to ensure a 100% sterile environment.

• Ready to Use: No soaking, boiling, or pressure cooking required. Simply inject and watch your mycelium thrive.
