Same grain; better bag. This larger bag allows easier shaking and optimized colonization as more grain is touching other grain and not the plastic, all while allowing us to ship them to you faster, easier, and cheaper: getting you the best price on the market!


Sorghum, also known as milo seems to be the superior mushroom grain spawn. It consistently outperforms rye, oats, or corn in our tests regardless of how we prepare them. Makes sense that the world’s largest spawn producers like Aloha Medicinals or Amycel seem to use the same grain we do.

Sorghum It has relatively high protein but most importantly it has a lot of surface area due to it’s small particle size. The more surface area the grain in your spawn bags has, the faster the mycelium will spread in the sterilized grain bag and the faster the colonized mushroom spawn will colonize the bulk substrate as it will more evenly and intimately mix through the bulk substrate providing lots of inoculating points. This speed reduces the risk of contamination and makes it so your mushrooms can fruit as fast as possible.

How to inoculate our grain bags:
