Installation for hydroponic cultivation. Of the type that have a pair of lateral rods (1, 1 ') in support functions with slope for a top sheet (2) with holes (8) for plant implantation, a lower sheet (4) closed in collector functions, and one or more intermediate sheets (3), with holes that determine a cascade path for the water with nutrients, the invention consists of providing a multilayer top sheet (2) in which four layers preferably participate (2a), 2b, 2c and 2d), which define between them narrow channels (7) for selective use, so that at the time of implantation the root of each plant is located in a channel (7) different from that used by the plants adjacent. Furthermore, it has been foreseen that the holes (8) for implantation of the plants, form two marginal and longitudinal alignments. In this way it is possible to keep the roots of the adjacent plants totally isolated during the first growth phase of the same, avoiding interferences between them and allowing the location on the installation of plants with different levels of growth and even plants of different nature. That in turn leads to a continuous production with a higher performance of the installation. (Machine-translation by Google Translate, not legally binding)Instalación para cultivo hidropónico. Del tipo de las que cuentan con una pareja de varillas laterales (1, 1') en funciones de soporte con pendiente para una lámina superior (2) con orificios (8) para implantación de las plantas, una lámina inferior (4) cerrada en funciones de colector, y una o más láminas intermedias (3), con orificios que determinan una trayectoria en cascada para el agua con los nutrientes, la invención consiste en disponer una lámina superior (2) multicapa en la que participan preferentemente cuatro capas (2a, 2b, 2c y 2d), que definen entre ellas estrechas canalizaciones (7) de uso selectivo, de manera que en el momento de la implantación la raíz de cada planta queda situada en una canalización (7) distinta de la ut
