The present invention relates to a hydroponic cultivation apparatus for sprout feeds, which performs seed sowing and germination growth in one container, and has an improved structure to optimize the growth environment of sprout feeds by supplying water to the sprout feeds at a temperature corresponding to the temperature in a cultivation chamber. The present invention comprises: a container which is divided into a seed chamber and a cultivation chamber, is formed in a box shape where six surfaces can be sealed, has an insulation material on an inner side, and has a cooling and heating air conditioner for controlling a temperature in the seed chamber and the cultivation chamber by being formed on the upper side a shelf plate which is symmetrically arranged on both sides of the left and right sides with respect to a center passage in the cultivation chamber, has a plurality of cultivation shelves vertically stacked on the frame, seats a plurality of cultivation plates on each of the cultivation shelves, and allows a front end portion of each cultivation shelf to be inclined downward toward the center an irrigation means including a water tank which is provided on the outer side of the container and has a water heater for controlling a water temperature inside, a supply pipe which is connected to supply water in the water tank to the upper side of each cultivation shelf with pressure of a pump, and a spray head for spraying water supplied to the supply pipe in a spray form on the upper side of each cultivation plate and a lighting means arranged on the upper side of the cultivation boards to emit LED lighting when external power is applied.본 발명은 하나의 컨테이너 안에서 종자 파종 및 발아 성장이 이루어지도록 함과 아울러, 새싹사료에 제공되는 물의 온도를 재배실 내의 온도에 대응되는 온도로 공급하여 새싹사료의 성장 환경을 최적화시킬 수 있도록 그 구조가 개선된 새싹 사료용 수경재배장치에 관한 것이다.본 발명은 내부가 종자실과 재배실로 구획되며, 육면이 밀폐가능한 박스 형태로 구성되고, 내측에 절연재가 배치되며, 상부에 종자실과 재배실 내의 온도 조절을 위한 냉난방공조기가 마련된 컨테이너와 상기 재배실 내에 중앙 통로를 기준으로 좌,우 양측으로 서로 대칭되게 배치되며, 프레임에 복수의 재배선반들이 상,하로 적층되고, 각 재배선
