We use our tried and tested blend of Coco Coir, Vermiculite and agricultural gypsum that is honed to reduce contamination and increase colonisation speed.

Perfect for spawning grain or PF tek cakes to bulk. For optimal results use 2-3x your grain weight so for 1kg of grain mix it with 2-3kg of CVG.

Goes perfect with our Fat Fungi Rye Grain bags. Check out our store for more mushroom grow supplies.
