Abstract: A plurality of selectively actuable watering stations are spaced about a selected location such as a lawn and/or garden and are connected to a source of pressurized water. A set of data is stored representing environmental conditions of the selected location, said conditions being selected from the group consisting of evapotranspiration rates for predetermined intervals throughout a given time period, and temperature precipitation rates for predetermined intervals throughout a given time period. Another set of data is provided from at least one input device at the selected location, the input device being selected from the group consisting of a temperature sensor, a rain gauge, a hummidity sensor, and a flow meter. Each watering station is actuated for predetermined durations at predetermined intervals based upon the data representing environmental conditions and the input device data to thereby ensure optimum growth of the plants situated in the selected location.
