Sterilized Grain Bags (3lb)North Spore
These bags are ideal for making your own master grain spawn. Each bag contains 3 lbs of pre-sterilized millet in a filter patch bag. These bags do not contain an injection port and are best suited for agar plate culture methods. If you are working with liquid culture try our sterilized grain bags with injection ports.
Millet is considered the gold standard grain for spawn production. Unlike traditional rye and wheat, millet has a lower endospore load and is less prone to contamination. The small size of the grains also means you get many more points of inoculation per lb of grain. Most growers find they can stretch their millet spawn more than spawn made with other grains.
