PLANT CULTIVATION DEVICE AND PLANT CULTIVATION SYSTEM

The present invention addresses the problem of developing a plant cultivation device having a small number of components and low energy consumption. The invention is configured by connecting a plurality of seedling raising units in series. The seedling raising units have a case in which both ends are open and the peripheral surface can be covered. A lighting device 16 is provided inside the case. The cases of the seedling raising units are connected, forming a series of cylindrical spaces, and a cultivation tray 38 is placed in the series of cylindrical spaces formed by the cases, said cultivation tray 38 spanning the cases and being movable downstream. The further downstream in the lighting device 16, the greater the number of light-emitting elements 205, the higher said light-emitting elements 205 are, and the greater the distance between the light-emitting elements and a seedling holding plate 41.
