Plant cultivation apparatus with uniform fluid dispensing system

摘要

A plant cultivation apparatus (10) that dispenses a uniform amount of fluid from a reservoir (14) to each of a plurality of plant receptacles (34) in apertures (32) by way of an open channel irrigation system. The system includes a first fluid dispensing unit (16) of a disc or saucer with concentric rings (76) about a central aperture (70); a second fluid dispensing unit (18) of a hollow cylinder (80) extending from a circular base (82) that has dispensing channels (84); and a valve (20) operated by a controller unit (21). The fluid from the dispensing channels is delivered by gravity to the plant receptacles via a respective shallow reservoir (36) and open channel conduit (38). The conduit is square shaped in cross section and can have a dividing projection (46) projecting upward from a centre location on the base wall (42) and extending along the length of the conduit.
