Abstract
Abstract The system includes an efficient, closed irrigation system in conjunction with insulating components for minimizing the harmful effects of extreme changes in ambient temperature, moisture and chemical concentrations in plant containers. Mechanisms are provided for permitting a single pallet, or a single plant within a pallet, to be readily removed from an integrated plurality of pallets without interfering with irrigation of the plants that are contained in the remaining pallets.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
182 words
A pallet for supporting a plurality of plants, each plant having roots contained within a container so that the plant shoots may extend above the container, comprising: a base having a bottom and sides; a top attached to the base, the top and base defining a compartment; container support means for supporting the containers within the compartment with the containers beneath the top, the top having a plurality of holes formed therein for permitting plant shoots to extend above the top; and insulating means for thermally insulating the top and sides of the base, the base constructed to define a reservoir for liquid stored within the compartment beneath the containers, the insulating means including a plurality of covers arranged for establishing a thermally insulating barrier between the containers and plant shoots extending therefrom, wherein each cover comprises a moisture impermeable, reflective, opaque, thermal-insulating member having an opening formed therethrough, the size of the opening being changeable so that plant shoot portions of various sizes may be surrounded by the flexible member, to prevent aerial-applied water from reaching the top of the containers.
Claim 2
Dependent Claim
182 words
A pallet for supporting a plurality of plants, each plant having roots contained within a container so that the plant shoots may extend above the container, comprising: a base having a bottom and sides; a top attached to the base, the top and base defining a compartment; container support means for supporting the containers within the compartment with the containers beneath the top, the top having a plurality of holes formed therein for permitting plant shoots to extend above the top; and insulating means for thermally insulating the top and sides of the base, the base constructed to define a reservoir for liquid stored within the compartment beneath the containers, the insulating means including a plurality of covers arranged for establishing a thermally insulating barrier between the containers and plant shoots extending therefrom, wherein each cover comprises a moisture impermeable, reflective, opaque, thermal-insulating member having an opening formed therethrough, the size of the opening being changeable so that plant shoot portions of various sizes may be surrounded by the flexible member, to prevent aerial-applied water from reaching the top of the containers.

Dependent Claim
27 words
The pallet of claim 1 wherein the insulating means also includes a layer of thermally insulating material attached to the top and the sides of the base.
Claim 4
Dependent Claim
62 words
The pallet of claim 1 further comprising irrigation means including a capillary mat carried by the container support means in contact with, and outside the container, the capillary mat being configured for transferring liquid to the containers, the irrigation means also including wicking means extending between the reservoir and the capillary mat for delivering liquid from the reservoir to the capillary mat.
Claim 5
Dependent Claim
25 words
The pallet of claim 3 further including level control means for establishing the level of liquid in the reservoir to be beneath the capillary mat.
Claim 6
Dependent Claim
26 words
The pallet of claim 1 further comprising level control means including a valve assembly connected to the base and operable for filling and emptying the reservoir.
Claim 7
Dependent Claim

The pallet of claim 1 further comprising coupling means for connecting the reservoir with a fluid-carrying conduit, the coupling means configured for opening fluid communication between the reservoir and conduit whenever the base is positioned adjacent to the conduit and for closing fluid communication between the reservoir and conduit whenever the base is moved from the position adjacent the conduit, the coupling means including a valve and stand pipe connected thereto and operable for establishing within the compartment a selected liquid level.
Claim 8
Dependent Claim
39 words
The pallet of claim 1 wherein the member is shaped as a truncated cone adjustable for defining the opening to be substantially circular irrespective of the size of the opening for supporting a plant shoot in an upright position.
Claim 9
Dependent Claim
30 words
The pallet of claim 2 wherein the bottom of the base is configured for placement in contact with an underlying surface for conducting heat between the reservoir and the surface.
Claim 10
Dependent Claim
141 words
A pallet for supporting a plurality of plants, each plant having roots contained within a container so that the plant shoots may extend above the container, comprising: a base having a bottom and sides; a top attached to the base, the top and base defining a compartment; container support means for supporting the containers within the compartment with the containers beneath the top, the top having a plurality of holes formed therein for permitting plant shoots to extend above the top, wherein the container support means includes an annular holder attachable to the plant container, the holder being hinged to open to permit movement of a contained plant out of the holder; and insulating means for thermally insulating the top and sides of the base, the base constructed to define a reservoir for liquid stored within the compartment beneath the containers.
Claim 11
Dependent Claim
141 words
A pallet for supporting a plurality of plants, each plant having roots contained within a container so that the plant shoots may extend above the container, comprising: a base having a bottom and sides; a top attached to the base, the top and base defining a compartment; container support means for supporting the containers within the compartment with the containers beneath the top, the top having a plurality of holes formed therein for permitting plant shoots to extend above the top, wherein the container support means includes an annular holder attachable to the plant container, the holder being hinged to open to permit movement of a contained plant out of the holder; and insulating means for thermally insulating the top and sides of the base, the base constructed to define a reservoir for liquid stored within the compartment beneath the containers.
