PROBLEM TO BE SOLVED: To solve the problem in which hydroponic cultivation requires an electric motor to be rotated to flow water and liquid fertilizer in order to cultivate plant roots in the liquid fertilizer.SOLUTION: There is provided a hydroponic cultivation planter having a double structure of an inner container and an outer container thereby to allow plant roots cultivated therein without using an electric motor. The plants are cultivated in the inner container. The outer container has a lid to seal inside the planter. The sealed structure can reduce the rate of natural evaporation of liquid fertilizer and prevent sunlight and other outside light from entering the inner container.SELECTED DRAWING: Figure 2 |
