3 lb Rye + CVG All-In-One Mushroom Grow Bag

Experience professional-grade mushroom cultivation with our Rye + CVG Casing All-In-One Mushroom Grow Bag (3 lb) — the ultimate ready-to-inoculate substrate system designed for gourmet and medicinal mushroom growers. Each 3-pound bag combines sterilized organic rye grain and a nutrient-balanced CVG (coco coir, vermiculite, and gypsum) casing mix, layered together inside one sealed bag for a complete colonization and fruiting environment. This heavy-duty 3 lb grow bag is engineered for reliability, consistency, and yield. The bottom layer features fully hydrated, sterilized rye berries that act as the nutrient-dense powerhouse for rapid mycelial colonization. Above that lies a perfectly balanced CVG casing layer that maintains moisture, supports pinset formation, and promotes multiple flushes. Whether you’re cultivating lion’s mane, oyster, shiitake, or reishi mushrooms, this substrate blend is formulated to deliver optimal performance across wood-loving and grain-loving species alike.
