The present invention relates to a hydroponics device. The hydroponics device includes: a housing (100) in which a plurality of parts are accommodated; a water tank (162) in which water and culture solution are stored; a cultivation plate (170) which is installed on top of the water tank (162) and on which a plurality of seeds or nursery plants are planted; a circulation passage through which the water stored in the water tank (162) is supplied and which guides water to circulate outside the water tank (162); a water circulation means (180) which is installed inside the water tank (162) and circulates the water stored in the water tank (162) through the circulation passage (210); a nutrient solution storage tank (240) which is placed on the circulation passage (210) between the water circulation means (180) and the water tank (162) and supplies nutrient solution to the water circulating through the circulation passage (210); and a light radiation member (300) which is installed in the upper part of the housing (100) and radiates light to promote the growth of plants. According to the present invention, by including the water circulation means inside the water tank to automatically circulate water and including a heating member to control the temperature of water depending on the kind of plants, it is possible to prevent the water from being spoiled or decomposed. Also, by preventing the water from being decomposed, it is not necessary to place an additional drainage installation inside the water tank. Furthermore, by sensing the level and temperature of the water automatically to maintain the appropriate environment for the growth of plants, the present invention improves user convenience in using the device. As the water and the temperature are controlled automatically, operation efficiency can be also improved. |
