Embodiment Construction

[0090] With reference to the accompanying drawings, first of all figure 1 , which shows a foam-making unit 1 for making liquid foam commonly used to grow plants, unit 1 comprising a coaxial duct or tube assembly 2 comprising an elongated air tube perforated along its length A supply conduit or tube 3 and an outer conduit or tube 4 arranged coaxially with the air supply conduit 3 is also perforated or otherwise liquid permeable along its length. The annular chamber 5 between the inner duct 3 and the outer duct 4 defines a mixing chamber in which the air from the duct 3 mixes with the liquid supplied to the annular chamber 5 . Surrounding the outer tubing 4 is a breathable layer 6 typically comprising resilient open cell plastic foam or any other breathable material. Foam or other material may be helically wound on the outer tubing 4 . Alternatively, foam or other material may be formed into a self-supporting sleeve that may be positioned around or house the outer tubing 4 . ...

Abstract

This invention relates to a method and apparatus for producing liquid foam wherein the liquid foam is used to facilitate the delivery of nutrients to plants. The method and apparatus comprises a foam production unit (1) comprising a chamber (5), inlet means (8,9) to said chamber (5) for oxygenated air and liquid, and means for controlling the flow of said oxygenated air and liquid through or from said chamber (5) to thereby create a liquid foam.

Description

technical field [0001] The present invention relates to a method and apparatus for producing liquid foam. In another aspect, the present invention relates to a method and apparatus for growing plants, and in particular, to a method and apparatus for assisting in the delivery of nutrients to plants using liquid foam. Background technique [0002] Oxygen-containing air foams are used in a wide variety of applications, including those for fire suppression in water-scarce areas. Different types of eductors are used to produce foam, however, each type of eductor known has disadvantages. [0003] Many different methods and apparatuses are used to grow plants, including those using conventional growing substrates such as soil or other solid growth substrates. Other methods and devices are available that use water as a growth substrate, such as those using hydroponics and other techniques. In such methods, the plants are grown by submerging their roots in a water-based solution c...
