Monotub Adhesive Filter Disks

The new Polyfil filter disks are being introduced in a bulk pack of 20, aiming to remove any uncertainty associated with the air exchange process. Crafted from a durable synthetic fiber resistant to water, these disks come with a 3M adhesive back. Engineered for optimal flow rate and density, they facilitate precise air exchange suitable for monotubs, indoor greenhouses (such as Martha Tents), or any bulk casing style grow. Effectively maintaining humidity levels, the disks allow for essential high levels of air exchange vital for tubs or greenhouses. Installation is a breeze - users can simply peel and stick them over any hole up to 2.25" in diameter. Furthermore, the disks are easily cleanable with Hydrogen Peroxide and can be reused for multiple growing cycles.
