Green Square Tank 520 Liters (119 × 77 × 84 cm)

Green Square Tank of 520 Liters

Made of hard and resistant plastic, the Green Square Tank of 520 Liters guarantees structural stability and intensive use in technical rooms, cabinets, and mixing rooms. The opaque finish minimizes light entry and helps prevent algae, while the lid reduces evaporation and protects the nutrient solution from dust and insects.

The square format optimizes usable surface: fits next to walls and corners, frees up corridors, and facilitates cleaning maneuvers.

The wide opening allows for quick filling, visual inspections, and hassle-free maintenance tasks.

With 520 L available, the flow to main lines of 16–25 mm remains stable, whether by gravity or with a pump, feeding branches with drippers, microtubes, or irrigation rings. The straight geometry favors clean fittings of irrigation accessories such as check valves, inline filters, and sector valves.

Ideal for coco and soil, as well as for NFT and DWC/RDWC systems (as a service tank), it offers a centralized point to adjust pH and EC, oxygenate with diffuser stones, and plan periodic purges.

The set integrates with programmers and controllers, providing predictability to the irrigation schedule and the nutrition of each bench, all with an orderly installation that favors inspections and internal audits.
