A kind of cultivated vegetables cultivation apparatus of water includes: the box unit that an output input connection unit, a control unit being electrically connected with output input connection unit and one are electrically connected with output input connection unit. The temperature and humidity in the box unit are sensed by the sensing element of a box unit, and the message for being sensed Hou passes the processing element of a control unit back through output input connection unit, the processing element is accordingly to be respectively started or close a light-emitting component, a heating element, a cooling element or one make mist element, so that temperature and humidity best and that be suitble to the seed growth germination can be maintained in the box unit, and then promote percentage of seedgermination.一種水耕蔬菜養殖裝置，包含：一輸出輸入連接單元、一與該輸出輸入連接單元電連接之控制單元，及一與該輸出輸入連接單元電連接之箱體單元。藉由一箱體單元之感測元件感測該箱體單元內之溫度與濕度，且將其感測後之訊息經該輸出輸入連接單元傳回一控制單元之處理元件，該處理元件據此以分別啟動或關閉一發光元件、一加熱元件、一致冷元件或一造霧元件，使得該箱體單元內可以維持最佳且適合該種子生長發芽之溫度及濕度，進而提升種子發芽率。
