Unpowered Wicking Irrigation Controller
Irrigation controllers rely on power for continuous operation. If there is a power failure or a battery runs flat, the irrigation stops and your plants may die. The Unpowered Wicking Irrigation Controller is the only irrigation controllers that does not need power. Provided the water supply is continuous, the irrigation controller will operate indefinitely.

Innovation and gravity feed irrigation
This video features a large garden in Adelaide using gravity feed irrigation from a header tank. A single zone can be used because the pressure at the tank outlet is the same regardless of the number of drippers. There are about 1000 non pressure compensating drippers and the pressure at each the dripper is about 50 cm. For conventional pressurised irrigation a pump is needed and the single zone would need to be replaced by many zones. The water usage is directly proportional to the prevailing net evaporation rate.

This video provides step by step instructions so that smallholders can use smart irrigation scheduling. All that is needed is a steel pipe and a storage container. Use for high or low pressure for any irrigation zone, big or small. The irrigation scheduling takes account of
the evapotranspiration of your plants, the soil type, and the depth of the root zone.

Gravity feed drip irrigation of my large native garden
This video has pictures of my beautiful Australian native garden. I will show you how to irrigate a garden with more than 1000 drippers so that you can set the volume of water delivered by each dripper during the irrigation. A unique feature of the irrigation system is that the volume of water delivered by each dripper is independent of the water supply pressure.
