PURPOSE: A plant cultivation system is provided to increase harvest yield of the culturing plants by making the optimum environment for plant growth and to contribute to the growth of plants according to the optical type. CONSTITUTION: An artificial weather information controller(100) receives the weather information and plant information, and inputs the correction value information to a terminal input-indication apparatus. The artificial weather information controller controls various apparatuses in order to optimize the environment for the growth of plants and displays the values. The weather information and plant information are transferred from a weather information providing server(300) and a plant information providing server(400) through the internet network(200). The various apparatuses are a humidifier and dehumidifier, automatic irrigator, lighting device, heater and cooling device. The correction value information is formed according to the plant type, weather information, location information and environmental change. The internet network wirelessly connects the artificial weather information controller, the weather information providing server and the plant information providing server. The weather information providing server transmits the regional weather information(310,320) to the artificial weather information controller through the internet network. The plant information providing server transmits the plant information according to the plant species to the artificial weather information controller through the internet network. The plant information providing server includes domestic and international plant information database(410) which stores the information about the domestic and international plants.
