Our CVG substrate provides the perfect growing medium for your mushrooms. Made with a premium blend of coco coir, vermiculite, and gypsum, this substrate ensures excellent moisture retention and nutrient availability, supporting rapid colonisation and minimising the risk of contamination.  

Optimal hydration is crucial for good substrate. There are some substrates on the market that come over-hydrated, resulting in slow colonisation and bacterial growth. Ours is perfectly hydrated to field capacity and sterilised in a computer-controlled industrial autoclave, so you can be confident of a successful harvest. 

There is also no need for expensive lab equipment or complex setups to get started. We’ve done the hard work for you by pre-preparing and sterilising fresh substrate in versatile, ready-to-use bags. 

Perfect for growers of all experience levels, our substrate makes it easy to produce fresh, therapeutic mushrooms right at home, even those varieties that are hard to find in stores. 

THE BENEFITS  

• Optimally hydrated coir, vermiculite and gypsum blend 

• Supports rapid colonisation for fast, healthy mycelium growth 

• Pairs perfectly with our Sterilised Millet Mushroom Grain Spawn 

• Guaranteed to produce mushrooms or we’ll replace your spawn free of charge 

• Save money by growing your own mushrooms at home 

• Little space required to grow & is discreet with no smells 

• Grow fresh, delicious mushrooms you can’t find in the shops   

HOW TO USE 

The process is simple:  

1. Spawning: Mix the substrate with fully colonised Sterilised Millet Mushroom Grain Spawn in a 2:1 ratio, ideally in a Monotub 

1. Colonisation: Allow the substrate to colonise for around two weeks 

1. Fruiting: After full colonisation, initiate fruiting conditions (airflow and light). Within a week or two, you’ll begin to see the first pins emerge 

Gone are the days of having to trawl through decade-old forum posts to figure out the fascinating but often confusing science that is growing mushrooms. Our step-by-step, easy-to-follow guide ensures a successful harvest, eliminating guesswork and making the whole process a breeze. 

INGREDIENTS  

Good ingredients make for excellent substrate. That is why we only use 100% natural and organic CVG blend in our kits. We only use the high-quality, natural ingredients for our products, specifically selected to support the optimal growth of mushrooms. 

Our tried and tested Sterilised CVG Mushroom Substrate Bag is a premium blend of coco coir, vermiculite, and gypsum. Carefully hydrated to field capacity and sterilised in a computer-controlled steam autoclave for 2 hours at 121°C.  

The result is a perfect substrate that retains moisture, provides essential nutrients and creates an optimal environment for mycelium development, ensuring rapid colonisation, large yields, and minimal risk of contamination. 

WHAT’S INCLUDED 

• 2kg or 3kg (depending on selection) premium blend of coco coir, vermiculite, and gypsum
