Our Button Mushroom Grain Spawn ensures a delightful homegrown experience with its small, white-capped appearance. Unlike supermarket variants, this product promises a more sustainable approach, free from plastic waste and additional carbon footprints.

The spawn is specially selected and double-tested to ensure it’s axenic, meaning it is free from competing species. This leads to an assured and satisfying crop of button mushrooms, whether you’re growing them at home or aiming for commercial production.
