Mushroom Cultures & Grain Spawn UK – 40+ Gourmet Strains

Buy Mushroom Culture Strains – Liquid, Agar, Grain & Plug Spawn

We offer a focused range of mushroom growing products designed for simplicity and reliability. Our liquid cultures contain live mycelium in sterile nutrient broth, ready to inject into grain for fast, clean colonisation. Grain spawn is fully colonised and ideal for use in bags, tubs, or trays with bulk substrate. For outdoor growers, our plug spawn consists of hardwood dowels pre-inoculated with mushroom mycelium—just drill into logs, insert, and seal. If you’d rather skip the setup, our ready-to-fruit blocks arrive fully colonised and can be fruited straight from the bag with a simple cut and regular misting. All products are prepared in sterile conditions and include clear instructions to help you grow with confidence.
