Inoculation Grain Jar Lids For Growing Mushrooms

(5) lids for $20. These lids are perfect for mushroom growers to inoculate their grain in mason jars. These lids have a thick synthetic filter disc for gas exchange and have a self healing injection port for liquid culture/spore syringes. These lids handle pressure cooking over and over again. Trust me I've been using some of my lids for YEARS. Every lid comes with a silicone sealing ring to ensure an airtight seal. Please advise if you want regular or wide mouth. I can also provide metal lids with the same setup at (5) for $12, but they do rust over time. **I supply mushroom growing equipment and supplies. Please reach out to me before buying online. I probably have what you're looking for and can provide to you the same day. Thank you for the support! **I also sell sterilized grain jars that include a quart mason jar filled 5/6th full of millet and includes the shown inoculation lid for $9 each. These jars are ready for inoculation
