ABSTRACT:
A self-watering plant device has a reservoir for retaining liquid therein. The reservoir is provided with a venting tube having one end attached to the reservoir and another end carrying a sensing device placed in the soil surrounding the plant for detecting the moisture level therein. The reservoir is further provided with an outlet tube for delivering liquid to the plant in response to the sensing device. The invention is improved such that the venting tube is flexibly displaced so that the sensing device is variably and selectively positioned at different height levels in the soil so as to establish the degree of wetness and dryness in the soil. The outlet tube is installed in the soil adjacent the bottom wall of a pot housing the plant to directly deliver a free flow of liquid to a bottom portion of the plant in response to the moisture level detected by the sensing device.
