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.
Claims6
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.
