ABSTRACT:
A self-watering plant pot consisting of an outer pot, a liner of translucent or semi-translucent material that fits within the outer pot, a soil platform assembly that divides the liner into a soil compartment and a water reservoir, an optional float positioned in the water reservoir, and a water delivery channel for allowing water and air to be introduced into the water reservoir. The water delivery channel can be a water delivery tube extending upward from the soil platform. The outer pot is typically opaque and includes a side window opening near its base. The water level in the water reservoir and, if a float is employed, the position of the float are visible through the liner and window opening in the outer pot. Water is conveyed from the water reservoir to the soil via capillary action.
