55 gal Drum with Locking Lid

A Large-Capacity Storage Drum for Water and Nutrient Solution, 55 Gal

Commercial-scale hydroponic operations need bulk water and nutrient storage that can be sealed against light and contamination, moved when necessary, and modified for tubing and fittings without cracking. This Active Aqua 55 gallon drum is built from food grade high molecular weight HDPE with a 2.2mm minimum wall thickness, sealed by a locking lid with a bolt ring closure that keeps the drum's contents secure and protected.

Standing 36.5 inches tall with an actual capacity of 57 gallons, this drum can be drilled for tubing or ports, making it a practical base for a larger reservoir, mixing station, or bulk storage setup in a commercial or high-volume home operation.

Frequently Asked Questions

What is the actual capacity of this drum?

While it's sold as a 55 gallon drum, its actual capacity is 57 gallons. That extra headroom leaves a small buffer above the labeled size.

What is the drum made of?

It's constructed from food grade, high molecular weight HDPE with a 2.2mm minimum wall thickness. That rating makes it suitable for direct contact with water and nutrient solution.

How does the lid seal?

The lid locks in place with a bolt ring closure, which compresses the lid against the drum's rim. This seals out light and contamination between uses.

Can I drill this drum for tubing?

Yes, the drum can be drilled for tubing or ports. This makes it adaptable for use as a mixing station, bulk reservoir, or feed source with fittings installed.

How tall is this drum, and will it fit under my bench?

It stands 36.5 inches tall, so it's worth measuring available clearance under a bench or shelf before planning to tuck it underneath. Many growers instead place it on the floor as a standalone reservoir or mixing station.
