PURPOSE: A hydroponic culture bed is provided to safely culture plants by facilitating the smooth supply and the drainage of the nutrition solution. CONSTITUTION: A bed body(20) comprises an inlet(21a) and an outlet(21b) in the same direction in order to receive and discharge the nutrition solution simultaneously. A second external wall faces a first external wall(21) having an inlet and an outlet. A third external wall(23) and a fourth external wall(24) meet the end portion of the first and the second external walls perpendicularly and face each other. A base(25) is extended horizontally from the bottom of the first through fourth external walls. A cultivation domain(26) is gradually lowered from the first external wall toward the second external wall so that the nutrition solution flows to the second external wall. A drainage groove(27) is gradually lowered toward the first external wall, and disembogues the nutrition solution passing through the cultivation domain to the outlet. A filling groove fills up the nutrition solution while containing the nutrition solution so as to disembogue to the cultivation domain. A collection groove(29) collects the nutrition solution while containing the nutrition solution so as to disembogue to the drainage groove. First through fourth inner walls(33) are protruded perpendicularly on the edge of the cultivation domain facing the first through fourth external walls. A supply slit is punched with a constant gap so that the nutrition solution evenly flows to the cultivation domain. A drainage slit(32a) is punched with a constant gap so that the nutrition solution evenly is collected in the collection groove. A cover(70) has holes(71) for passing leaves which grows from seeds and covers the cultivation domain.본 발명은 베드몸체(20)의 한쪽방향인 제1외벽(21)에 급수구(21a) 및 배수구(21b)가 함께 배열 형성되고, 선반(10)에 급수구(21a) 및 배수구(21b)가 동일한 방향으로 배치되도록 하여, 공급관(40) 및 배출관(50)이 동일한 방향에서 급수구(21a) 및 배수구(21b)와 연통될 수 있도록 함으로써, 즉 베드몸체(20)들의 제1외벽(21)이 한쪽방향을 향할 수 있도록 간단히 밀어주거나 당
