The sustainable agro-industry division of Gonvarri, Agrotech, was responsible for the construction of the High-Tech greenhouse, which is nearly 1,500 square meters and 7.5 meters high.

The greenhouse consists of two separate sections within the same structure: one for organic agriculture (tomatoes, cucumbers, peppers, lettuce, and eggplants) and the other for hydroponics (raspberries, strawberries, and blueberries).

Gonvarri Agrotech not only carried out the greenhouse’s construction but also managed the automation of the greenhouse and the open-field crops. The project presented various challenges, all of which were successfully resolved:

• Wide temperature variations between winter and summer months were addressed through the greenhouse’s large volume of air due to its height, the use of multiwall polycarbonate, natural ventilation systems, and the installation of a mixed thermal shading screen. This solution reduces the temperature inside during the central hours of summer days while retaining heat during winter, resulting in significant energy savings.
• High temperatures during the summer were reduced by installing a fans and pads cooling system that reduces the temperature by water evaporation, forcing hot air to pass through wet cellulose panels.
• Limited use of chemical products for pest control was achieved by installing anti-insect nets in the ventilation systems, preventing the formation of pests that could damage the crops. Maintaining a biologically controlled environment is crucial, especially in organic farming like this project.

This gothic greenhouse serves as a complement to the large ecological project of La Huerta de Hualdo.
