This paper proposes a technique of growing plants without soil using minimum usage of water. Sensors are connected to PIC Controller which monitors the supply of nutrients that requires for plant growth. In this project Internet of Things (IOT) is mainly used to regulate temperature, humidity, PH level , flow of water and nutrients. Correct air temperature, relative humidity, nutrient level of the water and correct irrigation of water is critically important in hydroponics. In this hydroponic system the user enables to control certain mechanisms for refilling, sprinkling, draining through web application. They can also monitor the pH level relative humidity and water level etc. which is data collected from the sensors.
