Vertical Hydroponic Tower 24 or 28 Slots – Tank in 3 Colors - Food-Grade Material for Growing

Vertical hydroponic tower kit with 24 or 28 plant sites with a 40-liter tank available in three colors, pump and tubes included: a modular column for growing salads, herbs and leafy vegetables while taking up little floor space, in a greenhouse, outdoors or indoors with adequate lighting. It is made of material suitable for food use and cultivation.

The tower is based on AquaNatura's LAGUNA column, designed and printed in Italy. The 40-liter tank supplies the column and each module retains a reserve of nutrient solution, so the roots always remain submerged, even if the pump stops for a while. Choose the 24-plant version (6 levels) or the 28-plant version (7 levels) and the tank color: white, green or black.

Why choose it

• Ready-to-connect kit: tower, tank, pump and tubes in the same package.
• 24 or 28 plant sites, 4 per level: 6 or 7 levels, for a height of approximately 2.0 m or 2.2 m.
• 40-liter water reserve: tank under the tower, measuring 38 × 28 × 61.5 cm.
• Roots always in water: reserve of solution in each module, with a more stable temperature.
• No clogging: the overflow is passive, without valves or drippers to clean.
• Easy harvesting: the plant basket is removed and takes the plant with intact roots, even for selling it live.
• Suitable for food use and cultivation: recyclable polypropylene (PP), UV-protected and opaque to limit algae growth.
• Modular: by adding levels, you can reach up to 32 plant sites (8 levels).
• Made in Italy: CE marked, with a patent application filed in Italy.

How it works

Water enters from the top and descends from one module to the next. Each module works like a small basin: with the provided extension tube, the water from the module above reaches the bottom of the cavity, renews the reserve around the roots from below, and the excess overflows into the internal overflow, then descends to the module below. Thus, each plant has its roots submerged in a solution that is constantly replaced, like on a floating panel, but vertically.

What you need to get started

In the kit you will already find the tower, tank, pump and tubes. To start, you need the nutrient solution, the seedlings (or seeds to germinate on sponges or cubes) and a tool to check pH and EC.

How to use it

1. Assemble the tower and position it; in the greenhouse, rows oriented north–south provide more uniform light.
2. Connect the pump to the supply: one line for each face, with balanced flow rates within 10%.
3. Fill the tank with the nutrient solution and oxygenate the water upstream of the pump.
4. Transplant the seedlings into the baskets: the three locking teeth keep them firm.
5. Check the level, pH and EC occasionally. In summer, a generous flow rate keeps the roots cool.
6. Harvest by removing the basket: the plant comes out whole, with its roots.

Results of field trials

In a trial at Moretto Farm (Crocetta del Montello, TV) in August 2026, 36 heads of lettuce on a LAGUNA tower were compared with 10 on floating, with the same surface area. AquaNatura's data indicate 41.7 plants/m² versus 18.3 (approximately 2.3 times) and a yield of 8.8 kg/m² versus 5.9 kg/m² (+49%, maximum estimate).

The trial was conducted under non-optimal conditions, with a flow rate lower than the design specification and without water temperature control.
