Prepare your own mushroom spawn with our Sterilised Rye Grain Spawn Bag, ready to inoculate with your chosen mushroom culture. With the grain preparation and sterilisation already taken care of, you can get started without soaking, cooking or pressure-sterilising rye at home.
Whether you’re starting your first mushroom cultivation project or preparing your next batch, this rye grain bag makes spawn production straightforward.
Ready for Your Next Mushroom Grow
Rye grain provides a nutrient source for mycelium as it develops through the bag. Once fully colonised, the grain becomes mushroom spawn, ready to mix with a suitable bulk substrate for your chosen species.
The clear bag lets you monitor colonisation, while the injection port provides access for syringe inoculation. A filter patch allows gas exchange during mycelium growth.

Prepare a clean workspace and follow the inoculation instructions supplied with your mushroom culture.
-
Inoculate the rye grain through the injection port using clean technique.
-
Allow the mycelium to colonise the grain under conditions suitable for your mushroom species.
