Brown button mushrooms, (Agaricus bisp. var. hortensis, champignon de Paris). Grain spawn only, not a growing set.
This grain spawn is intended for growing brown button mushrooms on a substrate of fermented horse manure. For detailed instructions on preparing the substrate see e.g.
1 liter grain spawn for 50 kg horse manure substrate. The mushrooms will grow faster if you use less substrate.
