MYCO-PRO™ Spawn Jar

Product Details
Brand: Spores Lab

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 either 350 grams of certified organic rye grain berries or 350 grams of certified organic oat grain berries - the two best mediums 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 rye grain or oat grain, the grain in this jar is UN-STERILIZED and UN-HYDRATED*
