Every grow needs a good base – that’s your mushroom substrate. It’s the stuff everything depends on, the quiet workhorse behind every decent flush. The right substrate for mushrooms gives your mycelium something solid and nutritious to feed on and sets you up for steady, healthy growth instead of hit-and-miss results.
Our mushroom substrate range includes the classic CVG substrate – a clean, balanced mix of coco coir, vermiculite, and gypsum, aka the go-to base for most gourmet mushroom growers, and the classic combo that delivers reliable results. Each bag of sterilised substrate is ready to use straight out of the pack. Just inoculate with your chosen liquid culture or spawn and keep conditions right for acclimatisation. No messy prep, no waiting around for pasteurisation.
If you’re new to it all, don’t stress. These mixes are forgiving. A solid mushroom growing substrate takes care of the complicated bits for you, leaving more time to actually watch the process unfold. Beginners and seasoned growers alike rely on this mix of consistency.
Ready to buy? Our stock consists of sealed, sterilised substrate bags that are perfect for use with our mushroom grow kits or your own setup. Perfect for experimenting with small test runs or producing larger yields, these mushroom-growing substrate options keep things simple and organic from the start.
Everything is prepared in sterile conditions for peace of mind and consistent performance.
Please not use our magic mushroom spores or any psilocybin-containing products with our substrate as this is illegal in the UK. Use only high-quality substrate for growing mushrooms of the gourmet and functional varieties.
