Monotub Filter Discs

Adhesive-backed polyfil filter discs for monotubs, shotgun fruiting chambers, grow tubs and any plastic container that needs filtered air exchange. Peel and stick over a drilled port — installs in seconds, no polyfil stuffing and no tape.

Ventilation holes are where contamination gets in. These discs let the chamber breathe and regulate humidity while blocking airborne spores and bacteria, which is the difference between a clean flush and a tub full of green mold. Custom manufactured to our specifications and reusable across multiple grows.

Specifications

Available in packs of 24, 48 and 300 discs. Growers running a full rack should note that a 12-tub case needs 48 to 72 discs depending on tub size, so the 300-count is the practical restock quantity for a production room.

Building tubs from scratch? Our Growers Select monotub cases ship with discs, plugs and liners included. For jars and culture vessels, use the smaller Microppose adherable lid filters instead.
