Sterile CVG Mushroom Substrate: Coco Coir, Vermiculite, Gypsum Blend- 5 lb

CVG (Coco Coir, Vermiculite, and Gypsum) is a staple bulk substrate blend used for mushroom cultivation. It is celebrated for its reliable moisture retention, structural aeration, and contamination resistance, making it an ideal, beginner-friendly foundation for a wide variety of gourmet, medicinal, and dung-loving mushroom species. The ingredients provide the following benefits to a mushroom grow: Coco Coir: Made from coconut husks, it provides the physical, water-retaining base. It acts as an excellent, contamination-resistant matrix that holds consistent moisture. Vermiculite: This naturally occurring mineral holds multiple times its weight in water and keeps the substrate mixture light and airy, preventing it from compacting. Gypsum: This mineral (calcium sulfate) provides trace amounts of calcium and sulfur, improves the texture of the mixture, and helps stabilize pH levels for stronger, vigorous mycelial growth.
