摘要：

A modular, expandable, self-regulating watering system for burial in planters, which do not have access to water pipes nearby for use in watering plants continuously with on the amount of water the plant needs and which can be refilled by relatively infrequent visits. The system is comprised of a plurality of hollow sections each of which has two upper ports and two lower ports, unless there are only two sections in which case only one upper port and one lower port is needed on each section. One section has a fill pipe that extends above the soil level. One section has an air port at the top thereof, or close to the top, which is coupled to an air tube, which is plugged at the other end with a hydrophilic sensor. Expansion sections can be added or subtracted to make the system larger or smaller. All sections are coupled together at their upper ports by flexible hose or tubing, and are coupled together by their lower ports by flexible hose or tubing.
