Save hours of work with our ready-to-use sterilized grain and substrate. We hydrate, sterilize and seal everything in filter-patch bags. So it is ready the moment it arrives.
Our sterilized corn spawn bags (2000cc and 4000cc) are ready to inoculate with a liquid culture syringe. Once the grain is fully colonized, mix it with our Simple Mix substrate. This mix is 75% coir and 25% vermiculite, and it comes in 2, 4 and 6 litre bags. The 6 litre size is ideal for a monotub. Note that we prepare our sterilized grain and substrate fresh, so shipping can take a little longer. Mixing your own? Read our mushroom substrate guide and learn about the role of gypsum in mushroom substrate.
