The first holds the growing material such as soil that provides nutrients and structure for plants to grow. The second holds a reservoir of water or liquid fertiliser to promote plant development. An inner shell form holds the growing material and an outer shell creates a cavity around the growing material that acts as the liquid reservoir. In normal use the reservoir is sealed to the atmosphere except for a series of small apertures in its base. These allow liquid to flow into the bottom of the growing material and spread by capillary action to the plant. This process continues until these apertures are covered by the rising liquid and a vacuum is established in the reservoir. When the growing material becomes sufficiently dry air is able to pass through into the reservoir again and more liquid flows out. This effectively regulates the amount of moisture to the plant. The amount of liquid flowing from the reservoir is controlled by a height differential in the water outlet and air inlet apertures. Excess liquid flow during filling of the reservoir is controlled by a series of channels, pockets and reservoirs in the bottom of the growing material. This eliminates the need for unreliable porous pads or very small liquid inlet holes to manage flow. In this way the invention creates a self-regulating gardening container that requires little maintenance and is easy to use.A 8 6 32 9 A 4 Figure 1 10 9 2 15 3 20 18 2 22 7 5 Figure 2
