These bags are ideal for making your own master grain spawn. Each bag contains 3lbs of a sterilized and hydrated proprietary organic grain blend. Each bag has a self-healing injection port for use with liquid culture or a spore syringe.

Sterilized grain bags can be stored for several months at room temperature before inoculation.

Once inoculated, allow your bag to colonize in a cool location out of direct sunlight. Temperature for incubation shouldn't exceed 75 degrees F or dip below 55 degrees. After a couple of weeks or so you should start to see mycelium growing on the grain.

Suggested retail is $16.
