Locally Sourced Organic Sterilized Rye Grain Bags Perfect for mushroom cultivation, our sterilized rye grain bags are made with 100% organic, locally sourced rye. Each bag is pressure-sterilized to ensure a clean, contaminant-free start, giving your mycelium the ideal environment to colonize. Ready to inoculate right out of the bag—no prep, no hassle, just reliable results for growers of all levels. Locally done @Saltygrows.
