Abstract
Abstract Cloches are disclosed for growing plants in desert areas where only salt water or brackish water is available. The cloches disclosed include a housing defining growing space for a plant or plants and a reservoir for water within the housing, the arrangement being such that water can be evaporated from the reservoir into the housing by solar energy to condense subsequently within the housing and water the plant or plants therein.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
An apparatus of substantially conical form for use in growing plants from seeds, bulbs, corms or the like, all hereinafter referred to for convenience as "seeds," comprising: a light transmitting generally impermeable housing of substantially frusto-conical form and comprising an outer frusto-conical wall and a coaxial inner frusto-conical wall; a reservoir within said housing, for liquid including or consisting of water, said reservoir occupying a relatively small part of said housing and being formed between said inner and outer walls of the housing; a trap disposed at the top of said housing, said trap including formations to assist the passage of water formed by condensing water vapour in said trap into the part of the interior of said housing below said trap, the latter part of the interior of said housing including a compartment for growth medium, said trap being located above the said reservoir and the said compartment for the growth medium being located beneath the said housing; means permitting the escape of water vapour from said reservoir into the interior of said housing while preventing the escape of liquid from said reservoir into the housing; and a membrane permeable to water vapour and separating said trap from said reservoir.
Claim 2
Independent Claim
201 words
An apparatus of substantially conical form for use in growing plants from seeds, bulbs, corms or the like, all hereinafter referred to for convenience as "seeds," comprising: a light transmitting generally impermeable housing of substantially frusto-conical form and comprising an outer frusto-conical wall and a coaxial inner frusto-conical wall; a reservoir within said housing, for liquid including or consisting of water, said reservoir occupying a relatively small part of said housing and being formed between said inner and outer walls of the housing; a trap disposed at the top of said housing, said trap including formations to assist the passage of water formed by condensing water vapour in said trap into the part of the interior of said housing below said trap, the latter part of the interior of said housing including a compartment for growth medium, said trap being located above the said reservoir and the said compartment for the growth medium being located beneath the said housing; means permitting the escape of water vapour from said reservoir into the interior of said housing while preventing the escape of liquid from said reservoir into the housing; and a membrane permeable to water vapour and separating said trap from said reservoir.
Claim 3
Dependent Claim
65 words
The apparatus of claim 1 including a detachable layer of moisture impervious material, covering said membrane, whereby such detachable layer may be kept in place until such time as it is desired to use the apparatus when the said moisture impervious layer may be removed in order to place the trap and the reservoir in communication with each other through the pores of the membrane.
Claim 4
Dependent Claim
50 words
The apparatus of claim 1 which comprises three parts which may be rigidly but detachably secured together namely, a first part comprising the said housing and reservoir, a second part comprising the said trap and a third part comprising the compartment for the growth medium and seed to be grown.
Claim 5
Dependent Claim
28 words
The apparatus of claim 3 constructed from plastics material and in which the frusto-conical walls surrounding the housing are at least partially formed from translucent or transparent material.
Claim 6
Dependent Claim
27 words
The apparatus of claim 1 including baffles for promotion of condensation of water vapour and serving to direct the condensed water vapour onto the said growth medium.
Claim 7
Dependent Claim
42 words
The apparatus of claim 1 and including means for temporarily sealing the said growth medium and seed within the growth compartment until such time as it is desired to promote the growth of a plant from the seed within the growth medium.
