Our biggest yielder in the grow room. This abundant producer and can fruit in a wide range of temperatures ranging from 55-80˚F.
Oyster grain spawn can be used to inoculate dowels for log culture or to inoculate substrate for fruiting. A wide variety of substrates can be used as a fruiting medium. Some of our favorites are coffee grounds, wheat straw, hardwood sawdust/wood-shavings, and cardboard. This 4 lb bag of grain spawn comes sterile in a sealed bag with a microfilter patch. Grain spawn is best used fresh but can be stored for short periods in a refrigerator. We use certified organic grain for all our grain spawn.
