Claim 5

An arrangement for growing plants, comprising: a multiplicity of individual containers each having a bottom wall, side walls and an open upper face, said containers being at least partially filled with a medium for growing plants and being stacked in the form of a self-supporting column, and all containers above the lowest one being supported at least indirectly by a container positioned below, the stacking formation allowing an open space to remain between the side walls of upper and lower containers or between projections thereof; drain means in at least the side walls of said containers for allowing excess fluid to exit therefrom; and an excess fluid draining system communicating with a lower container of said column.

Claim 6

An arrangement for growing plants, comprising: a multiplicity of individual containers each having a bottom wall, side walls and an open upper face, said containers being at least partially filled with a medium for growing plants and being stacked in the form of a self-supporting column, and all containers above the lowest one being supported at least indirectly by a container positioned below, the stacking formation allowing an open space to remain between the side walls of upper and lower containers or between projections thereof; drain means in at least the side walls of said containers for allowing excess fluid to exit therefrom; and an excess fluid draining system communicating with a lower container of said column.

Claim 7

An arrangement for growing plants, comprising: a multiplicity of individual containers each having a bottom wall, side walls and an open upper face, said containers, except a lowest container, being at least partially filled with a medium for growing plants and being stacked above said lowest container in the form of a self-supporting column, and all containers above the lowest one being supported at least indirectly by a container positioned below, the stacking formation of said container above the lowest one allowing an open space to remain between the side walls of upper and lower containers or between projections thereof; drain means in each container for allowing excess fluid to exit therefrom; and excess fluid draining system communicating with said lowest container of said column.

Claim 8

An arrangement for growing plants, comprising: a multiplicity of individual containers each having a bottom wall, side walls and an open upper face, said containers, except a lowest container, being at least partially filled with a medium for growing plants and being stacked above said lowest container in the form of a self-supporting column, and all containers above the lowest one being supported at least indirectly by a container positioned below, the stacking formation of said container above the lowest one allowing an open space to remain between the side walls of upper and lower containers or between projections thereof; drain means in each container for allowing excess fluid to exit therefrom; and excess fluid draining system communicating with said lowest container of said column.

Claim 9

A plant growing and irrigating arrangement comprising: a multiplicity of individual containers each having a bottom wall, side walls and an open upper face, at least most of said containers being at least partially filled with a medium for growing plants and being stacked in the form of self-supporting plurality of columns, and all containers in a column above a lowest one being supported at least indirectly by a container positioned below, the stacking formation allowing an open space to remain between the side walls of upper and lower containers or between projections thereof; drain means in each container for allowing excess fluid to exit therefrom; draining network means in fluid communication with said columns for collecting excess fluid exiting from said columns; irrigating network means including an array of fluid emitting orifices disposed above said columns; and excess fluid recycling means for propelling said excess fluid from said draining network to said irrigating network.

Claim 10

A plant growing and irrigating arrangement comprising: a multiplicity of individual containers each having a bottom wall, side walls and an open upper face, at least most of said containers being at least partially filled with a medium for growing plants and being stacked in the form of self-supporting plurality of columns, and all containers in a column above a lowest one being supported at least indirectly by a container positioned below, the stacking formation allowing an open space to remain between the side walls of upper and lower containers or between projections thereof; drain means in each container for allowing excess fluid to exit therefrom; draining network means in fluid communication with said columns for collecting excess fluid exiting from said columns; irrigating network means including an array of fluid emitting orifices disposed above said columns; and excess fluid recycling means for propelling said excess fluid from said draining network to said irrigating network.

Claim 11

The arrangement as claimed in claim 6 further comprising means for conditioning said excess fluid prior to propelling the fluid to said irrigating network.

Claim 12

A plant growing and irrigating arrangement in accordance with claim 6, wherein all said containers in each said column above the lowest container are supported by a sidewall of the container immediately positioned therebelow, all said containers in a column being generally the same size, said drain means in each said container comprising at least one hole provided in a sidewall of said container, said draining network means comprising an individual fluid collection means for each column, and means for collecting together said individual drainage collection means, and said arrangement further comprising means for purifying fluid collected by said draining network means prior to passage to said fluid recycling means.

Claim 13

A plant growing and irrigating arrangement according to claim 8 wherein said irrigating network means comprises a venturi aerator.

Claim 14

The arrangement as claimed in claim 1, 4, 5 or 6, wherein the side walls of said container slope upwards and outwards.

Claim 15

The arrangement as claimed in claim 1, 4, 5 or 6, wherein at least some of the upper containers have a smaller base area than containers below them.

Claim 16

The arrangement as claimed in claim 1, 4, 5 or 6, wherein the walls of each of said containers form a polygon having corners and wherein said containers are stacked so that each upper container is skewed, relative to the container supporting it, at an angle, providing plant space near the polygon corners.

Claim 17

The arrangement as claimed in claim 1, 4, 5 or 6, wherein said drain means are one or more holes made in at least one of said side walls above said bottom wall.

Claim 18

The arrangement as claimed in claim 13 wherein fluid supply is arranged to provide for irrigation, fertilizer, pesticide or any combination thereof.

Claim 19

The arrangement as claimed in claim 1, 4, 5 or 6, further comprising light reflecting surfaces placed adjacent to said drain means for directing light thereon.

Claim 20

The arrangement as claimed in claim 1, 4, 5 or 6, wherein said lower container communicates with said draining system via a transparent conduit directly connected to said system.

Claim 21

An arrangement as claimed in claim 1, 4, 5 or 6, wherein each said container is only partially filled with said medium for growing plants, and wherein said bottom wall of each upper container is spaced above said medium for growing plants in a container therebeneath so that each said bottom wall does not come into contact with growing medium therebeneath.
