The main objective of an irrigation system is to supply adequate and timely water to plants. With precision agriculture, irrigation zones should be selected based upon plants' irrigation water requirements and sized according to available water supply. Designing and having precise control of multiple zones enables separate and distinct watering requirements for turf, drought tolerant vs. non drought tolerant landscape plants and herbaceous garden plants (vegetables and flowers). An irrigation zone does not have a predetermined size, but should be selected by an area or group of plants that have similar watering needs, and in the case of RainCloud, can be serviced by the water supply from a 3/4" garden hose. Therefore, a single zone RainCloud could be used to water a group of potted plants, one or more areas of your lawn, one or more garden beds, etc. This is possible by using various irrigation techniques downstream of RainCloud (e.g. drip or micro irrigation, rotary sprinklers, etc.) that can proportionally adjust application rates, but with one valve, watering for all areas in a zone will occur at the same time and frequency.
