Our wide-mouth Grain Culture Lids have the best injection ports and filters available.  Plus, they are made at Cloud Culture Mushrooms.  These lids are made for sterilizing grain to make grain spawn.  Each lid comes with a high grade platinum-cured silicone gasket to prevent any leaks, and a filter patch for air exchange.  They are autoclavable, heavy duty, reusable, and work awesome!

Pro tip:  Screw the lids on loosely so the silicone seal presses lightly on the jar rim.  This will prevent possible warping of the sides of the lid while pressure cooking.  Tighten immediately upon removal from a pressure cooker.
