To use your Adhesive Jar Filter Discs, drill a ¼”-⅜” hole into a standard lid and apply your adhesive disc to the top of the jar – each filter is fully autoclavable and sterilizable, but you can use foil or a silicone jar lid cover to protect your filters during the sterilization process.

Adhesive jar filter discs allow for air exchange to promote mycelial growth while preventing unwanted spores and airborne particulates from entering sterile grain spawn or liquid culture. Air exchange promotes stronger mycelium and more rapid growth.
