In known systems that symbiotically combine plant and fish cultivation, the upper planting container (02) is rigidly connected to the lower water container (03), so that only the entire system (01) can be rotated. Bending forces from the plants can cause instability. In the invention, the planting container (02) and water container (03) are rotatably mounted on top of each other by means of a rotary bearing (46), so that the planting container (02) can be rotated independently of the water container (03). Furthermore, a support plate (31) is connected to a base tray (08) on the planting container (02) via a support device (11), so that any forces occurring are transferred into the base tray (08). A water circulation between the water container (03) and the planting container (02) is created via an inlet device (19), whereby the inlet device (19) does not rotate with the planting container (02).The water container (02) is mounted on support legs (16) and can also be rotated independently via casters (17). This allows for optimal, separate alignment of the plant container (02) and water container (03) according to functional and aesthetic considerations. A variety of additional components, also serving functional and aesthetic purposes, can be optionally installed. The aquaponic growing system (01) is particularly suitable for home use, where a single large plant is cultivated. With scaling, it can also be used for private food production.
