Spawning Mushrooms is most often performed in a glass mason jar, however Spores Lab has developed a product that not only works better, but is also more cost effective.
This thick-walled Polypropylene Plasic Jar is fully autoclavable, and can withstand several cycles in a pressure cooker without warping or deforming. This jar is perfect for spawning any species or strain of mushroom mycelium, and features a removable lid that has both a self-healing injection port for easy inoculation, and a 0.2 micron filter port to allow the air/gas exchange necessary for optimal colonization speed.
This jar is sold pre-filled with 350 grams of certified organic rye grain berries - the best medium for spawning mushrooms, OR just as an empty jar. Select the option that you would like from the drop down menu above.
*If purchasing with grain, the grain in this jar is UN-STERILIZED and UN-HYDRATED*
350g of Locally Sourced, Certified Organic, Non-Fungicide Canadian Rye Grain Berries (optional)
