In order to be able to utilize a hydroponic system in the best possible way and at the same time to secure the best possible growing conditions for the plants, including especially the supply of oxygen to the roots in the simplest possible way, the system is built up by means of a plurality of fluid containers (1) with an overflow (2 or 17) and with an upper section (3). In this upper section (3) a nutrient substrate (4) e.g. consisting of foam can be mounted e.g. in a way to permit the formation of an air space (5) between the substrate (4) and the fluid (15). The fluid is led to the container by means of a tube (6) ending at the bottom. This secures the supply of nutrient and oxygen to the roots. To secure the outlet from the container a tube (8 or 9) is arranged that is supplied with apertures (10) at the top at an equal distance to each other. Accordingly, arches (7) with projections (11) are provided in the bottom, so that the container can be 'locked' firmly to the tubes. One of the tubes (8, or 9) may further act as a drain for the fluid, which can drip from the container down into the apertures (10) of the tube, either through an external overflow (2) or through an internal overflow (16), ending in a tube stub (17) at the bottom of the container. |
