Generally, hydroponic cultivation is a cultivation method in which plants are cultivated using a culture solution in which various necessary nutrients are dissolved in water, instead of supplying water and various nutrients required for plant growth from the soil.

Such hydroponic cultivation is known to harvest the uncontaminated clean vegetables and crops because it does not use pesticides harmful to human body, and it is known that it can obtain a large amount of yield in a relatively short period of time.

Accordingly, various hydroponic cultivation apparatuses capable of hydroponically cultivating have been disclosed in the past, for example, in Registration Practical Utility Model No. 20-0261098, Registration No. 10-0459631, and Registration No. 10-0761253.

However, the conventional hydroponic cultivation apparatuses disclosed are techniques for improving the technical aspect of supplying the culture liquid to hydroponic plants more smoothly, and the following problems are encountered.

There is a problem in that the efficiency of energy used in hydroponic plants is low in terms of energy from cultivation in the soil. In other words, in the case of general cultivation, there is a merit that natural light is not used separately, and in the case of hydroponic cultivation, excessive power is used in circulation for supply of culture liquid for hydroponics.

In addition, there is no specific design for ascending and descending paths for supplying the culture liquid and a method for passing the power supply line when cultivating hydroponic plants, or there is a problem that the paths occupy a large space unnecessarily by separately designing the respective passages, Occurs.

In addition, since it is impossible to adjust the stacking volume for the hydroponic plants loaded in a multi-layer structure, it is difficult to install in a narrow space such as an apartment or an office room in the structure of the apparatus, There has been a problem in that it is unnecessary to make a custom design through a separate design.
