Abstract
To grow a plant which stores nutrients synthesized in an above-ground part into an underground part, a hydroponic cultivation apparatus waters the underground part. The hydroponic cultivation apparatus includes: a void portion housing the underground part while establishing a substantially sealed state; a sensor which detects an amount of moisture in the void portion at the underground part or around the underground part; an air conditioning fan which introduces outside air to the void portion and controls temperature and humidity inside the void portion; and a controller which controls the amount of moisture detected by the sensor by driving the air conditioning fan in such a way as to adjust an amount of the outside air or an introduction period of the outside air.
