These 100% high-temperature silicone lid covers are designed to protect
your lid filters and injection ports from steam, making them an
eco-friendly alternative to foil. Their unique molded design allows for
gas exchange during sterilization and channels water droplets to the
side during cooling. This feature helps extend the life of your lid
filters by preventing water pooling on them as your jars cool down in
the sterilizer. Made from food-grade silicone, these lid covers are both
renewable and autoclavable, with a high-temperature tolerance of up to
400°F. By using these covers, you can significantly prolong the life of
your adherable filters and injection ports, reducing waste and ensuring
better performance.

We teamed up with Micropose in 2019 to create the original Monotub disk to say goodbye to polyfil! Our disks are rated for proper air flow unlike many cheap knockoffs. We take the guess work out of the air exchange equation with our newly designed Polyfil filter disks. Constructed from a durable synthetic water resistant fiber and 3M adhesive back, these disks have the perfect flow rate and density to allow the right amount of air exchange for monotubs, indoor greenhouses (Martha Tents) or any bulk casing style grow. They keep humidity in and allow for the high levels of air exchange needed for any tub or greenhouse. Simply peel and stick over any size hole up to 2.25" diameter. Can be cleaned with Hydrogen Peroxide and re-used for multiple grows.
