ABSTRACT:
A self-watering and self-drying planter assembly with a water reservoir open to the air and a top downward system for supplying water into the soil through built-in water-feeding channels, each having a water-transfer control lever for controlling the quantity of water supplied to the soil in the planter.
The planter assembly automatically controls the amount of water and nutrients supplied to said plant by controlling the periods of water feeding and the intervening dry periods. There is an inner container assembly including an inner container for receiving a plant and soil, an outer container spaced from and surrounding the inner container and defining therebetween a water-receiving chamber, and a water-supplying chamber below for receiving water from said water-receiving chamber. A float assembly automatically supplies water from the water-receiving chamber to the water-supplying chamber in response to the water level in said water-supplying chamber. The water-feeding channels are connected to the water-supplying chamber for transferring water from the water-supplying chamber to the water-feeding channels for watering the plant.
