Abstract: A hydroponic cultivation system includes a plurality of hydroponic cultivation units vertically stacked one over another. Each hydroponic cultivation unit is configured to provide a cultivation bed for the plants. Every two neighboring units are hydrologically coupled to one another such that the culture solution flows top-to-bottom through each hydroponic cultivation units on each level. A plurality of support members, such as pipes, are disposed between, and provide mechanical support for, two hydroponic cultivation units on every two neighboring levels. A light source is disposed over a bottom side of one hydroponic cultivation unit on an upper level and can emit a plant-compatible light to support growth of the plants being cultivated on another hydroponic cultivation unit on a level immediately below the upper level. The hydroponic cultivation system can achieve a vertical recycling of the culture solution.

Abstract: A configurable hydroponic cultivation device includes a tank. The tank includes at least one separation bar and at least one removable dam member. The at least one separation bar is disposed on a bottom side of the tank and is configured to separate the tank into a plurality of trough regions. The at least one removable dam member is configured to be removably mounted in the tank to thereby block the culture solution from flowing therethrough. The at least one separation bar and the at least one removable dam member are configured to allow a configurable passageway for the culture solution flowing in the tank. Due to its modular features, the configurable hydroponic cultivation unit can be stacked one another to form a multi-level hydroponic cultivation system, which achieves a vertical recycling of the culture solution.
