Hydroponic Tower for Commercial Greenhouse Lettuce and Herb Growing in Portugal

In Portugal, a greenhouse grower with many years of experience in vegetable production has been rethinking how to increase yield and gradually scale up production within existing commercial greenhouse facilities as market conditions evolve. With limited land availability, expanding greenhouse space would require high investment and long construction timelines, making it an impractical option for an operating greenhouse. As a result, the grower began exploring hydroponic growing systems with higher space efficiency.

After comparing several cultivation solutions, he decided to introduce the 12P15 vertical hydroponic tower system into his existing greenhouse for the production of hydroponic lettuce, hydroponic herbs, and mint—common crops for daily consumption. Compared with traditional horizontal growing methods, vertical hydroponic towers use a vertical growing structure that transforms planting space from a flat layout into a three-dimensional system, significantly increasing planting density inside the greenhouse.

Each 12P15 hydroponic tower provides 180 planting sites while occupying less than one square meter of floor space. Without changing the main greenhouse structure, previously scattered growing areas were reorganized into a more compact and orderly vertical hydroponic growing zone. After the layout adjustment, the number of plants per square meter nearly tripled compared to the original horizontal setup, while clear working aisles were still maintained for daily management and harvesting.

After receiving the hydroponic equipment and completing the first full growing cycle, the customer reported an increase in overall greenhouse yield along with improved daily management efficiency. Based on the current operating results, the grower is now planning to deploy the same type of vertical hydroponic tower system in a second commercial greenhouse to further expand the production of hydroponic vegetables and herbs.

From this customer’s practical experience, vertical hydroponic tower growing systems offer a realistic way for commercial greenhouses to increase planting density within limited space. For greenhouse growers looking to improve space utilization and optimize crop structure through hydroponic technology, this approach provides strong reference value and scalability potential.
