PROBLEM TO BE SOLVED: To provide a hydroponic apparatus and a hydroponics method, in which water quality of water flowing inside a cultivation vessel can be further uniformized.SOLUTION: A hydroponic apparatus 10 comprises: an inflow part 51 for allowing water to flow into a cultivation vessel 20 an outflow part 52 for allowing water to flow out from inside the cultivation vessel 20 and a water flow direction control part 100 for controlling the water flow direction of water in the cultivation vessel 20. Further, the inflow part 51 includes a plurality of inflow lines 51a, 51b, 51c, 51d which can be opened and closed, the outflow part 52 includes a plurality of outflow lines 52a, 52b, 52c, 52d which can be also opened and closed, and the water flow direction control part 100 controls changeover between opening and closing of at least one line among the plurality of the inflow lines 51a, 51b, 51c, 51d, and the plurality of the outflow lines 52a, 52b, 52c, 52d.COPYRIGHT: (C)2014,JPO&INPIT【課題】栽培容器内を流れる水の水質をより均一化させることのできる水耕栽培装置および水耕栽培方法を得る。【解決手段】水耕栽培装置10は、栽培容器20内に水を流入する流入部51と、栽培容器20内から水を流出する流出部52と、栽培容器20内の水の水流方向を制御する水流方向制御部100と、を備えている。また、流入部51は開閉可能な流入ライン51a,51b,51c,51dを複数備え、流出部52は開閉可能な流出ライン52a,52b,52c,52dを複数備えている。そして、水流方向制御部100が、複数の流入ライン51a,51b,51c,51dおよび複数の流出ライン52a,52b,52c,52dのうち少なくとも1つのラインの開閉を切り替え制御するようにしている。【選択図】図2
