Mark 1 Medium Mushroom Monotub

The Medium Monotub is a streamlined, mid-sized solution for cultivators who want professional-grade results in a manageable format. With a 44-quart capacity, it's the ideal balance of volume and footprint—large enough for significant yields, yet compact enough to fit on standard shelves or grow racks.

Constructed from super-dense, injection-molded polypropylene, this monotub is built to last through multiple grow cycles without warping or cracking. The outer dimensions measure 18" L x 15.5" W x 12" H, giving it a wide, stable base and excellent airflow circulation across the substrate surface.

Equipped with six strategically placed air exchange holes, the tub promotes balanced FAE (Fresh Air Exchange) to support healthy mycelium and mushroom development. Included plugs offer control over airflow, allowing growers to fine-tune conditions during colonization or other sensitive stages.

A custom-fit liner is included to reduce side pinning, streamline cleanup, and keep your substrate contained during fruiting. The stackable design with reinforced lid and base supports up to 10 tubs securely, making this a space-efficient choice for scaling your operation.

This listing includes:

• 44-quart monotub (top and bottom)
• Heavy-duty securing clips
• Custom-fit liner
