ABSTRACT:
An apparatus for the delivery of water, nutrients or other liquid materials to the growing medium of potted plants, including a refillable chamber for the storage of the liquid, and means for attachment of the chamber to the vessel in which the growing medium is maintained. The chamber is equipped with a rigidly supported wick in the shape of an inverted U, one end of which is equipped with a float support, holding the wick in the liquid storage chamber. This allows adjustment of the depth of the wick into the chamber. The other end of the wick is inserted in a rigid passageway co-located with the growing medium. The apparatus is also equipped with an adjustable moisture-sensitive brake mechanism, regulating the movement of the wick support in relation to the liquid level in the refillable chamber thereby regulating the flow of liquid from the refillable chamber to the growing medium.
