PURPOSE: A plant cultivating apparatus is provided to control the supplying state of nutrition solutions economically and efficiently. CONSTITUTION: A plant cultivating apparatus comprises: a tray (20) accommodating nutrition solutions for growing plants; a light illuminating unit (30) illuminating light to the tray; a nutrition solution retrieving container (50) connected to a circulating pump and a supplying pipe supplying the nutrition solution to the tray; a first retrieving pipe portion (41) protruding with a fixed height from the bottom of the tray, and retrieving the nutrition solution which exceeds a fixed water height level; and a nutrition solution retrieving device (40) comprising a second retrieving pipe portion (45) with a control valve which retrieves the nutrition solution and selectively blocks the flow of the nutrition solution. The plant cultivating apparatuses are equipped in multi-stages by being laminated. The first retrieving pipe portion and the second retrieving pipe portion are connected to each other in a row, and connected to the nutrition solution retrieving container by mutually joining in the lower end. The control valve is controlled by a control part to open and close the second retrieving pipe portion with a set cycle. Guide rails installed in the both sides of the tray are equipped to be slid forward and backward by contacting to a roller placed inside a cabinet. |
