Patent attributes
A hydroponic cultivation system includes a plurality of hydroponic cultivation units vertically stacked one over another, each configured to provide a cultivation bed for the plants and including: a tank with an integrated structure; separation bars on a bed of the tank; a planting board; a plurality of removable dispensers, and a plurality of removable dam members. Every two neighboring hydroponic cultivation units are hydrologically coupled to one another such that the culture solution flows top-to-bottom through each of the plurality of hydroponic cultivation units on each level. The removable dam members and the separation bars are configured to facilitate flexible control of depths and passageways of a culture solution flowing in the tank, thereby allowing for convenient switching between a deep cultivation mode and a shallow cultivation mode to support different growth stages of plants being cultivated in the tank of the hydroponic cultivation unit.
