Mushroom Grain Spawn Jars With Reasuable Lids, 100% Organic Rye Berries

Introducing our Rye berry grain spawn! These 32 Oz mason jars come pre-sterilized and are soaked in gypsum and coffee to maintain perfect PH balance for fast Mycelium growth. They are ready to inoculate and the jars are wide mouth, making it easier to break apart spawn. The updated lids can be reused and with these filters you do not need to use tin foil when re sterilizing, they do not leak and are water tight. We use Microppose ports and filters and have found the filter and Injection port can be re-sterilized and used up to 3 times. The grain is perfect for inoculation because of the multiple points of injection between the rye. For medicinal and gourmet mushrooms only. Thanks for looking!
