The device has a tubular shaped elongated container (1) containing a substrate (7), and a pressurized liquid/nutrient mixer i.e. Venturi effect exhauster, including a main inlet connected to an irrigation liquid distribution rail. A U-shaped nutrition and irrigation pipe/tube (4), is arranged in the substrate and extended along a longitudinal direction of the container. The pipe has a wall provided with longitudinal slots (6) whose length is based on fluid pressure that reigns inside the pipe/tube at its level. |
