At Mushroom Hut, we prepare all our grain spawn fresh to order, ensuring you receive high-quality, viable mycelium. We keep a limited stock of grain spawn to maintain freshness and avoid the decline in quality that can occur with long-term storage. This means you receive fresh, active spawn every time—giving you the best chance of success when growing mushrooms at home.

Grain spawn is a starter culture and needs to be mixed with a suitable growing substrate—such as pasteurised straw or supplemented sawdust—which you'll need to prepare separately.

All made-to-order products typically require up to 21 days to be prepared and dispatched. On average, most orders are ready within approximately 10 days.
