Green Square Tank 300 Liters (77 × 62 × 83 cm)

Green Square Tank of 300 Liters

Made of hard and resistant plastic, the Green Square Tank of 300 Liters provides structural stability and reliability in technical rooms, cabinets, and intensive workspaces.

The opaque wall limits light passage and helps prevent algae, while the lid reduces evaporation and blocks dust or insects, preserving the nutrient mix for longer.

The rectangular format optimizes usable surface: perfect fit against walls or corners, leaving corridors free and handling areas more comfortable.

The wide opening makes filling, cleaning, and checking the interior easier, and the straight perimeter allows for neat installation of fittings, check valves, filters, and irrigation accessories. With 300 L available, the system maintains a homogeneous flow to main lines of 16–25 mm and microtube branches, either by gravity or with a pump.

Ideal for coco, soil, NFT, and DWC/RDWC as a service tank, as well as for preparing and homogenizing nutrients with pH and EC control.

The stable geometry allows for secure fixings and combination with oxygenators, timers, and sector valves, achieving a measurable, clean, and easy-to-maintain supply within an online grow shop focused on performance.
