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 plastic ring and
3M adhesive back, these disks have the perfect flow rate and density to
allow the right amount of air exchange for monotubs 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 2.0" diameter. Can also be re-used!
