Plant pot assembly

Claim 2

A plant pot assembly comprising: a growth medium container having substantially contiguous upwardly tapering sidewalls and an upwardly opening mouth to define a truncated conical contour, said container made of a porous material, said sidewalls terminating in a lip portion at said mouth, covering means made from a material which is substantially impermeable to liquids, said covering means having an inner surface following the contour of at least the majority of the outer surface of said sidewalls, where said covering means is operationally separated from said outer sidewall surfaces to form a capillary space therebetween, said covering means extending over said lip portion of the container and entering said mouth, whereby liquids can be drawn upwardly within said capillary space and released into said mouth of said container, and a collection tray below said container and in fluid communication with said capillary space, said container having at least one aperture providing fluid communication between the inside surfaces of the container sidewalls and the collection tray.

Claim 3

A plant pot assembly as recited in claim 1 further comprising an outer enclosure surrounding major portions of said container and said covering means, said enclosure having a condensation surface which inclines towards said outer surface of said sidewalls, said mouth of the container exposed to the exterior of the outer enclosure.

Claim 4

A plant pot assembly as recited in claim 2 wherein said enclosure is sealed to said container and said covering means to provide a sealed evaporation volume within said enclosure.

Claim 5

A plant pot assembly as recited in claim 3 wherein said sidewalls of said container and said covering means are provided with apertures which permit gas, vapor, and other fluids to flow between said evaporation volume and an interior volume of said container due to pressure differentials therebetween, whereby vapor saturated air may be forced, under pressure, into said interior volume from said evaporation volume to provide both irrigation and aeration.

Claim 6

A plant pot assembly as recited in claim 4 wherein said enclosure includes a base portion adapted to contain a supply of irrigation fluid.

Claim 7

A plant pot assembly as recited in claim 5 wherein said collection tray overlies said base portion of said enclosure, said collection tray being adapted to collect fluid runoff from said covering means and said condensation surface, whereby said supply of irrigation fluid and said fluid runoff are separated by wall portions of said collection tray.

Claim 8

A plant pot assembly as recited in claim 6 further comprising a platform disposed within said interior volume of said container having a support surface for supporting growing medium, where said platform, said container, and said covering means permit fluid communicaton between said collection tray and a volume beneath said support surface of said platform.

Claim 9

A plant pot assembly as recited in claim 1 wherein said container is made from a porous material, whereby fluids may be drawing upwardly within said sidewalls of said container by capillary action.

Claim 10

A plant pot assembly comprising, a porous growth medium container having an upwardly tapering sidewall and an upwardly opening mouth defining a truncated conical contour, said sidewall terminating in a lip portion at said mouth, a collection tray positioned below said porous container for the collection of liquid, said collection tray being in fluid communication with said container, a platform wall spaced apart from the collection tray and attached to the lower portion of said sidewall of the container to define a container interior above said platform wall, said platform wall having at least one platform aperture therethrough, a covering having a contour substantially identical to the truncated conical contour of said container, said covering spaced apart from said container to form a capillary space in fluid communication with said collection tray, said covering extending over said lip portion of the container and entering said mouth, said covering made of a material impermeable to liquid, said sidewall of the container and said covering having coinciding side apertures therethrough, and an airthight enclosure encasing at least the major portion of said sidewall of the container to define an evaporation volume, said mouth of the container extending above the enclosure, said enclosure being in fluid communication with said collection tray and with said side apertures of the container sidewall and the covering, whereby vapor saturated air may be forced into the container interior through said side apertures from said evaporation volume and through said platform aperture from said collection tray.

Claim 11

A plant pot assembly comprising, a porous growth medium container having an upwardly tapering sidewall and an upwardly opening mouth defining a truncated conical contour, said sidewall terminating in a lip portion at said mouth, a collection tray positioned below said porous container for the collection of liquid, said collection tray being in fluid communication with said container, a platform wall spaced apart from the collection tray and attached to the lower portion of said sidewall of the container to define a container interior above said platform wall, said platform wall having at least one platform aperture therethrough, a covering having a contour substantially identical to the truncated conical contour of said container, said covering spaced apart from said container to form a capillary space in fluid communication with said collection tray, said covering extending over said lip portion of the container and entering said mouth, said covering made of a material impermeable to liquid, said sidewall of the container and said covering having coinciding side apertures therethrough, and an airthight enclosure encasing at least the major portion of said sidewall of the container to define an evaporation volume, said mouth of the container extending above the enclosure, said enclosure being in fluid communication with said collection tray and with said side apertures of the container sidewall and the covering, whereby vapor saturated air may be forced into the container interior through said side apertures from said evaporation volume and through said platform aperture from said collection tray.

Claim 12

The plant pot assembly as recited in claim 9 wherein said airtight enclosure has a condensation surface downwardly inclined toward said sidewalls of the container.

Claim 13

The plant pot assembly as recited in claim 9 wherein said airtight enclosure includes a base portion adapted to contain a supply of irrigation fluid, said collection tray spaced apart from said supply of irrigation fluid by a wall.

Claim 14

The plant pot assembly as recited in claim 9 wherein the spacing between said platform wall and said collection tray is partially filled with a supply of fluid, the area immediately above said supply of fluid being airtight other than through said platform aperture.
