The present disclosure provides a configurable hydroponic cultivation unit and system. The configurable hydroponic cultivation unit can include a tank. The tank comprises 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.
