100 Gal Square Reservoir - Black - 51 x 51 x 13-in

Low-Profile Square Reservoir for Under-Tray Setups - 100 Gal

Growers who run flood trays need a reservoir that fits beneath the tray without taking up extra height. This square reservoir stands 13 in tall on a 51 x 51 in footprint, so it slides under flood trays and holds a large volume of nutrient solution. Measurement markings along the inner walls let you check the fill level at a glance.

At 100 Gal, this size suits growers running a full indoor room or a commercial hydroponic setup who want fewer refills between nutrient changes. Hobbyists with a small system will likely prefer a smaller reservoir in the same line.

Key Features & Benefits

• Inner wall measurement markings — lets you track volume while mixing or topping off.
• Black colour — suits setups where you want an opaque tank.
• System compatibility — works with flood trays, aeroponic and modular systems.

Who Should Use 100 Gal Square Reservoir

Use it if you run flood trays, aeroponic or modular hydroponic systems and need a large nutrient reservoir with a low profile. It suits indoor rooms and commercial cultivation with enough floor space for a 51 x 51 in tank.
