Abstract
A device for injecting aqueous nutrient solution (2) for hydroponic culture constituted of substantially horizontal supply pipes (9) located in the air space (3), held against the lateral walls (10) of the tank (1), injecting the nutrient solution (2) in the form of droplets through injection orifices (11) on opposed, substantially horizontal trajectories, thus improving their gaseous transfer capacity and their penetration into the nutrient solution to accomplish a continual saturation of this nutrient solution (2) with oxygen.
