  • Patent number: 7748930
    Abstract: A system and method for efficiently delivering an aqueous solution to plants includes a microporous hydrophobic tubing coated with a hydrophilic polymer that has a distal portion positionable adjacent a root system of a plant and a lumen for channeling an aqueous solution from an inlet to the distal portion. The tubing along the distal portion has a porosity adapted for permitting a flow of the aqueous solution therethrough when acted upon by a surfactant root exudate generated by the roots due to water stress. A pressure regulating device is upstream of the tubing's inlet, and a reservoir adapted for holding the aqueous solution therein is situated in fluid communication with an upstream end of the pressure regulating device. Additional tubing can be provided for channeling a nutrient solution to the plant roots.

    Abstract: An irrigation system for watering a substrate, comprising a pipe having a longitudinal dimension. A hermetically closeable inlet portion is connected to a water supply. A passageway extends generally throughout the longitudinal dimension and is in fluid communication with the inlet portion such that water can fill the passageway. Openings are in fluid communication with the passageway such that water in the passageway can exit the pipe through the openings. The openings are distributed along the longitudinal dimension of the pipe, the pipe being adapted to be at least partially buried in the substrate with said longitudinal dimension being generally horizontal. Porous members are secured to an outer periphery of the pipe so as to each cover one of the openings and so as to be in contact with the substrate such that water flows out of the passageway through the openings and the porous member and into the substrate as a result of a capillary action of the substrate.

    Abstract: A plant pot drainage system has a pot or planter-type container with potting soil. Lightweight, non-mineral rock shaped filler elements are located in the lower section of the container. The elements are irregular in shape, allowing the potting soil to fill spaces between the elements. This promotes drainage and proper root growth within the container. The elements are formed from synthetic, crush-proof material, for example high strength plastic, and can be hollow, to enhance the lightweight nature of the elements. Use of these filler elements ensures that the planted container can be easily lifted and readily transported.

    Abstract: A self-watering plant device has a reservoir for retaining liquid therein. The reservoir is provided with a venting tube having one end attached to the reservoir and another end carrying a sensing device placed in the soil surrounding the plant for detecting the moisture level therein. The reservoir is further provided with an outlet tube for delivering liquid to the plant in response to the sensing device. The invention is improved such that the venting tube is flexibly displaced so that the sensing device is variably and selectively positioned at different height levels in the soil so as to establish the degree of wetness and dryness in the soil. The outlet tube is installed in the soil adjacent the bottom wall of a pot housing the plant to directly deliver a free flow of liquid to a bottom portion of the plant in response to the moisture level detected by the sensing device.

  • Patent number: 5896701
    Abstract: A hydroponic cultivation receptacle comprising a tray 22 having a board 22a to place seeds of small vegetables like sprouts has plural drainage holes 23 on the board 22a and upper rims of said drainage holes 23 to form protrusion 24 so as to retain a little amount of water to dip lower part of the seeds placed on the board 22a. Accordingly, water remained to the height of protrusion 24 retains enough water to keep lower part of the seeds by surface tension while most water provided inside tray 22 drained from the drainage holes 23. Protrusion 24 prevents the seeds from moving from the place they are uniformly placed and the problem of moving of the seeds when water is poured is also solved.

  • Patent number: 5822919
    Abstract: This invention relates to a method for growing high protein natural vegetation on a reservoir system using only a a small section of land comprising of a trench of precalculated size dug in a suitable site close to wildlife; predetermined layers of lime, pine bark, polymer, fertilizer, bacteria, and soil; a water and water soluble fertilizer delivery system consisting of a netted polystyrene aggregate, sheet of kraft paper, and inserted rigid pipe with openings at either end; and natural vegetation either potted or transplanted from the wild; whereby the natural vegetation reservoir system allows for regular irrigation and fertilization of said vegetation growing on said trench, thereby allowing said vegetation to uptake said fertilizer and be ingested by said wildlife.

  • Patent number: 5351438
    Abstract: A planter container for growing a house plant in soil or a growth medium which contains multiple vent pipes extending vertically from the bottom to the top of the container. Air convection occasioned by the natural water transpiration processes of the growing plant is sufficient to cause polluted air flow through the vent pipes, and the vent pipes then enhance air flow throughout the root growth medium, exposing the air to large surface areas of plant root and biologically active growth medium for enhanced microorganism removal of volatile organic chemicals.

  • Patent number: 5247762
    Abstract: A controlled release hydraulic watering system for either an individual plant pot or for a plurality of potted plants. The system utilizes a porous terra cotta water-receiving reservoir which, through permeation, can distribute water either into an individual potted plant at a controlled release rate without over-watering the plant contained therein or onto a capillary sheet and horticultural matting used in an irrigating tray containing a plurality of potted plants providing a proper amount of water to the tray for watering all the plants contained therein. The terra cotta reservoir may include an exterior side wall covering of horticultural matting, silica sand and a plastic sheet.

  • Patent number: 5189835
    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.
