PURPOSE: A hydroponic culture facility is provided to minimize a facility for a nutrient solution supply and a water level control which were mounted in each cultivator. CONSTITUTION: A frame(1) comprises four perpendicular frames(11) installed vertically and a horizontal frame(12) forming the mounting space of multi-stage perpendicularly by connecting mutual perpendicular frames. A nutrient solution acceptance panel(2) comprises a settlement section(21) for settling a cultivator growing plants, one or more nutrient solution saving protrusion(22) forming a nutrient solution acceptance part(23) in which nutrient solution is stored, a water level control drainpipe(24) making a nutrient solution higher than an optimal water level fall down, a complete drainage hole(25) formed to be penetrated in the other side of a water level control drainpipe. A nutrient solution storage tank(3) forms a water level sensor(31) sensing a given or higher water level and a drainage hole. A nutrient solution supply pipe(4) supplies nutrient solution to a nutrient solution acceptance panel(2) located in the top by a nutrient solution supply pump(41). The upper end of a drainage pipe(5) is connected to a water level drainage pipe in the lower surface of a nutrient solution acceptance panel(2) so that given or higher water level of nutrient solution is flowed in, a drainage pipe equips with a first valve, and the lower end is located in the nutrient solution acceptance panel of an adjacent lower part or the upper surface of a nutrient solution storage tank. A second drainage pipe(6) equips with a second valve(61) in the center, and the lower end comprises a second drainage pipe located in the nutrient solution acceptance panel of an adjacent lower part or the upper surface of a nutrient solution storage tank. The bottom surface of a nutrient solution storage tank is made of a V shape formed in a slope from center to both ends. |
