All-in-One Mushroom Grow Bag (4 lb)

This sterile grow bag combines grain spawn and bulk substrate in one ready-to-inoculate system, allowing you to inject spores or liquid culture, incubate, and fruit with minimal equipment.

Each bag includes a pre-sterilized blend of grain spawn and bulk substrate inside a self-supporting filter bag with a self-healing injection port.
