Sterilized Grain is the cornerstone of mushroom cultivation. It can be inoculated in a variety of ways in order to start and propagate at mushroom culture. For example, you can purchase  Liquid Culture (LC) from LightningSpore, and inject the grain bag using the injection port. In addition, you can use a grain-to-grain transfer technique in order to expand a vigorously growing mushroom culture, which is already on grain, to multiple grain bags.

We offer grain bags in two different sizes: 1lb and 3lb.

All of our grain bags include an injection port.

All grain bags are prepared with utmost care, sterilized in a commercial sterilizer, and are ready to be used!
