This all-weather strain fruits at a broad temperature range and is great for all-season production. 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.
Spawn may need to be grown to order and can take up to three weeks. Please call or email with any questions.
