| abstract |
Apparatus for cultivating plants comprises a vessel ( 15 ) for receiving a plant cultivating medium ( 10 ), the vessel wall having a number of apertures ( 30 ) which are substantially covered over by a water-permeable polymer ( 35 ) which controls introduction of aqueous media ( 25 ) into the vessel ( 15 ). The vessel ( 15 ) and polymer ( 35 ) sit in a reservoir ( 20 ) for the aqueous media ( 25 ). The polymer ( 35 ) may be water-swellable and may be a hydrogel and preferably is in the form of a film, membrane, layer or sheet having a thickness in the range 0.001 mm to 5.0 mm. The polymer ( 35 ) supports transport of the aqueous media ( 25 ) through the thickness of the polymer ( 35 ) by diffusion so that entry of aqueous media ( 25 ) into the vessel ( 15 ) by hydraulic or capillary flow is prevented. The diffusion rate is self-controlled by the plant species. |
