2lb bag of master grain spawn. These bags are inoculated with fresh, vigerous, cultures. These bags are perfect to expand several times or they can be used to inoculate sterilized substrate. We use a mix of rye, oats, and millet to achieve good nutrition and as many innoculation points as possible.
2 week processing time as all spawn is made to order, ships usps priority mail.
please contact us if you would like to set up a scheduled reoccuring order.
