Abstract: By using internet and new materials technology, the structure of indoor intelligent soilless cultivation is designed based on WiFi. The whole structure consists of tubular soilless cultivation device, environmental factor device, and spray cultivation device. The tubular soilless cultivation device is mainly composed of cultivation pipes, supports and fixed cup, the spray cultivation device is mainly composed of nutrient liquid culture barrels, automatic timing water supply equipment, nutrient liquid intake pipes and reflux pipes, air pumps, sprinklers, etc. The device of environmental factors is composed of individual system of temperature, humidity, CO2 and light. The temperature, humidity, CO2 concentration and light in the structure are important factors affecting vegetable growth and development. By WiFi, the groove of these factors can be achieved for the growth and development of vegetables.
