Sterile Grain Bag,Please allow your sterilised grain bag to sit for 1-2 weeks upon arrival to be sure product was not compromised during transit. Sterilised 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 23º c or dip below 12°c. After a couple weeks or so you should start to see mycelium growing on the grain.

Shake up the syringe thoroughly to distribute the mycelium and flame the needle until red hot. Cool down the needle with alcohol and inject 3-6ccs into a self-healing injection port. Once inoculated, let your bag colonise in a place away from direct sunlight at a temperature of 12-23 degrees Celsius.
