Premium Sterilized Red Milo Grain Bag — 3 LB

Give your mushroom cultures the cleanest possible start with our Sterilized Grain Bag, packed with red milo (grain sorghum) — a favorite substrate among cultivators for its optimal moisture retention, nutrient profile, and excellent surface area for mycelium attachment.

Why Red Milo?

• Dense, hard grain resists premature breakdown during sterilization
• Ideal moisture content for fast, even colonization
• High surface-area kernel shape encourages robust mycelium contact
• Works with a wide range of gourmet and medicinal mushroom species

Self-Sealing Injection Port

Each bag features a self-sealing silicone injection port, allowing you to inoculate with liquid culture or spore solution without ever opening the bag — dramatically reducing contamination risk and keeping your grow environment sterile from start to finish.

Ready to Inoculate

Fully sterilized and ready to use right out of the box. Simply inject your culture through the port, shake to distribute, and let colonization begin.
