Ryeberry Spawn Bags: The Classic Workhorse

Why Our Ryeberry Bags Just Work (The Inocblock Difference)

• Superior Hydration Control: Ryeberries naturally absorb and retain water more evenly than wheat or millet, giving you perfectly hydrated kernels that won’t clump, burst, or create anaerobic pockets.
• Commercial Sterility Assurance: Every batch is sterilized in a 150L industrial autoclave at 127°C for over five full hours, ensuring deep core-level sterility all the way to the center of the grain.
• Reduced Bacterial Risk: Rye has a firmer shell and lower starch leakage than softer grains, dramatically lowering the chances of bacterial wet spots when your culture begins to colonize.
• Optimized for Mycelial Speed: The size and shape of rye kernels create more inoculation points, allowing mycelium to jump from kernel to kernel quickly and consistently.
• Perfect Nutrient Profile: Ryeberries offer one of the most balanced nutrient profiles among all spawn grains—rich in complex carbohydrates, micronutrients, and trace minerals that nearly every fungal species thrives on.
• pH-Balanced Prep: We prepare all rye using pH-adjusted water, creating conditions that favor clean, fast mycelial colonization while making life difficult for molds and contaminants.
• Handled in HEPA-Filtered Air: All final loading and sealing happens in a sanitized workspace using HEPA-filtered laminar airflow to eliminate airborne contamination risk.
• Fresh, Not Stored: We produce rye spawn in small batches and ship quickly—bags are never held longer than five days so your grain arrives fresh, hydrated, and biologically active.

Choose Your Volume: Options & Sizes

• 1 lb (The Starter): A perfect test size for trying new cultures, running small projects, or doing quick expansion work.
• 2.5 lb (The Standard): Our most popular size—ideal for a standard monotub, greenhouse grow, or multiple shoebox-style containers.
• 5 lb (The Workhorse): Built for bulk production and G2G transfers. Expand your spawn into multiple bags or fuel large grow operations with ease.
