Abstract
In a process for hydroponic cultivation of plants an irrigation solution containing water and at least one nutrient is circulated through a main loop at a first point where a disinfectant is added to the irrigation solution. At a second point at least one nutrient is added to the irrigation solution. At a third point the plants are supplied with the irrigation solution, and at a fourth point the irrigation solution drained of the plants is collected. The main loop is provided with one or more sub-loops through which the irrigation solution is recirculated.
