ABSTRACT:
A device comprising a porous, open-celled block, such as wood or foam plastic, having substantially parallel, opposed, planar major surfaces and adapted in size to support a single flower pot. A plastic tape, which may be perforated or unperforated, is wrapped around the block and covers at least half of each of the major surfaces of the block. The tape has a thin, single-particle-thick layer of quartz sand attached to the inner surface of the tape in close, non-adherent relation with the major block surfaces. The sand particles are interspersed with a network of capillary spaces which are conductive to lateral spreading of water along the layer.
The invention also includes a support block of a predetermined size and height having a single side panel that includes the plastic perforations and the quartz sand single layer proceeding up to the top plastic layer on the styrofoam block.
The invention also shows an alternate embodiment using a terra cotta or clay plant pot with no drain hole in the center bottom surface of the pot used in conjunction with a tray matting, a capillary layer which controls the water flow.
