<p>A device for injecting nutritive aqueous solution (2) for hydroponic cultivation consists of approximately horizontal supply tubes (9), located in the air volume (3) and held against the side walls (10) of the container (1), which inject the nutritive solution (2) in droplet form through injection ports (11) along approximately horizontal opposing trajectories (12). This improves the capacity of the droplets for gas transfer and their penetration into the nutritive solution and hence ensures that the nutritive solution (2) is permanently saturated with oxygen.</p> |
