Growers Select 66 Quart Monotubs, Filter Disk, Plugs & Liners (12-Pack)

A wholesale case of twelve 66 quart Growers Select monotubs, molded from high-density polypropylene and shipped with every part needed to build them out: filter disks, hole plugs and fitted liners included.

The 66 quart is the largest tub we stock and the one to run when you want the fewest chambers to maintain for a given volume of substrate. The deeper bed holds more spawn and substrate per tub, which means more mushrooms per flush and fewer tubs to mist, fan and monitor. The tradeoff is weight when full and a longer colonization window, so it suits growers who already have their process dialed in.

Case includes

• 12 × 66 quart monotubs with tight-fitting lids
• 72 adhesive filter disks (six ventilation ports per tub)
• 72 adjustable airflow hole plugs
• 12 fitted liners

Specifications

• High-density polypropylene construction
• Six strategically positioned ventilation ports per tub
• Airflow plugs allow ports to be sealed during incubation and opened for fruiting

A monotub is a sealed fruiting chamber: a deep tub with a tight lid, ported for controlled gas exchange and filtered against contamination. Plugs stay in during colonization to hold carbon dioxide high, then come out to trigger and support fruiting. It remains the most productive low-tech method for bulk-substrate species.
