The sterile, high-quality organic blend of coco coir, vermiculite, and gypsum ensures optimal moisture retention and nutrition, fostering robust growth and huge yields. Each bag has 5 pounds of sterilized substrate ready for use.
Simply add your colonized grain spawn and let the magic happen. We recommend using 2-3 pounds of colonized mushroom grain spawn for every 5 pounds of CVG substrate. Coco coir based substrate is the cleanest way to grow mushrooms that have traditionally grown in manure or compost. Easy to follow instructions included.

At The Mushroom Merchant, we take pride in producing high-quality mushroom cultivation supplies designed for every level of grower. Our CVG substrate is a sterile, perfectly balanced blend of coco coir, vermiculite, and gypsum. Each batch is mixed, hydrated, and sterilized under controlled conditions to ensure consistency, cleanliness, and performance.
This CVG substrate is made with 100 percent organic, plant-based ingredients and contains no animal manure or agricultural waste. The blend provides an ideal structure for mycelium development, promoting rapid colonization and healthy fruiting. Growers choose CVG because it offers a cleaner, more dependable alternative to waste-based substrates.
Every bag arrives sterile and pre-hydrated for immediate use. Simply spawn to bulk or grow directly in the bag. The 5-pound size offers the right balance of fast colonization and ample nutrition for multiple flushes under proper growing conditions.
Whether you are a beginner or an experienced cultivator, this CVG substrate delivers consistent results. The combination of coco coir for structure, vermiculite for moisture retention, and gypsum for essential minerals supports vigorous mycelium growth and dependable yields across many edible and gourmet mushroom species.
CVG substrate, short for coco coir, vermiculite, and gypsum, has become the standard in clean, reliable mushroom cultivation. It retains moisture exceptionally well, offers balanced aeration, and resists contamination. As a result, it is one of the most trusted choices for both hobby and professional growers cultivating edible and gourmet mushrooms.
Getting started is simple. Each bag arrives fully hydrated and sterilized, requiring no preparation. It is ready to use straight out of the box. Mix colonized grain spawn with the CVG substrate, let it colonize, then open the bag to fruit. It’s that simple. Full instructions are included with each bag of substrate. You can also follow our step-by-step CVG Instructions or check out our Mushroom Growing Guide to learn how to inoculate, incubate, and fruit your mushrooms successfully.
