CVG stands for coco coir, vermiculite and gypsum and is a great substrate for growing manure loving, medicinal, button and portabello mushrooms.

Our sterilised CVG is made with certified organic coco coir hydrated with double filtered water free from all chemical nasties before blending with the perfect amounts of vermiculite and gypsum. Before posting, your CVG substrate enjoys an extended stay in our industrial autoclave ensuring sterility and optimum results.

Sterilised CVG (Coco Coir, Vermiculite, Gypsum) Substrate – UK Supplier

Our Sterilised CVG Substrate is a widely used bulk substrate for growing a variety of dung-loving mushroom species. It consists of coco coir for moisture retention, vermiculite for aeration, and gypsum for essential minerals, providing an optimal growing environment for mycelium to colonize and produce healthy fruiting bodies.

Suitable Mushroom Species

CVG is ideal for cultivating species that thrive in high-humidity, nutrient-rich environments, including:

  • Portabello
  • Button
  • Other dung-loving medicinal and therapeutic fungi 

Production & Sterilisation

  • The production process begins with mixing high-quality raw ingredients to field capacity to ensure proper hydration before its packed into genuine Unicorn XLSA mushroom bags. Each batch undergoes heat sterilisation in our industrial autoclaves for three hours at 121°C (15 PSI) to eliminate contaminants. After sterilisation, the substrate is carefully cooled inside a cleanroom in front of a laminar flow hood, ensuring sterility before sealing and distribution.

How to Use

  1. Inoculation: Introduce colonised grain spawn to the substrate using sterile techniques.
  2. Incubation: Store in a suitable environment at the recommended temperature for the mushroom species.
  3. Fruiting: Once fully colonised, expose to fresh air, light, and proper humidity levels to trigger fruiting.

This sterilised CVG substrate is ready to use, contamination-free, and designed for efficient colonisation and fruiting. Suitable for both beginner and experienced growers looking for a reliable, high-quality bulk substrate.

  • Supplement Options: Available with additional supplements such as chopped straw and chicken manure to further enhance growth.
  • Recommended Pairing: For best results, use our substrate in combination with our best-selling sterilized millet or rye grain bags.
