Abstract: A plant nutrient delivery system comprises a sensor, an electronically actuated valve and an electronic controller. The sensor is positionable in plant growing media and operable to detect a condition of the plant growing media. The electronically actuated valve has a connection to a liquid nutrient source. The electronic controller is linked to the sensor and to the electronically actuated valve. The controller is programmed to carry out automatic demand-based nutrient delivery to the plant growing media by controlling the electronically actuated valve to turn on and off based on signals received from the sensor regarding a condition of the plant growing media, thereby causing a flow of the liquid nutrient into the plant growth media to start and to stop. Methods are also described.
