ABSTRACT:
A vessel for automatically sustaining vegetation includes a lower container for storing a reservoir of liquid, an upper container for supporting the vegetation and receiving liquid from the lower container, and a flow regulator for controlling the flow of liquid to the vegetation. The upper container is engageable with the lower container and includes a stem, defining at least one passageway, for extending into the liquid. The flow regulator includes a member which defines a flow port and which is rotatably attached to the stem of the upper container. In one embodiment the flow regulator may be controlled from outside the vessel by means of a control arm extending from the member. The upper container preferably includes drain holes permitting the drainage of excess liquid from the vegetation and permitting aeration of the vegetation, while the lower container preferably is transparent for viewing the liquid level and includes a fill/drain opening for adding liquid without disassembling the vessel and for permitting the drainage of excess liquid from the lower container. The upper and lower containers are preferably tapered in their cross-sectional dimensions from top to bottom to permit the nesting of a plurality of such vessels and thereby facilitate handling, storage, and shipment. The cross-sectional dimensions of the upper and lower containers are additionally preferably arranged so that the assembled vessel presents a unitary appearance with a constant taper from top to bottom.
