Learn How to Save Water with: Education

Revolutionise your watering with advanced controllers

Drought and water restrictions in many parts of Australia have shown us that water is a scarce and precious resource. Many gardeners have found to their surprise that their plants survived, even thrived, despite receiving less water due to restrictions. In other words, most gardens are regularly over-watered. Just because water restrictions permit watering at a certain time doesn’t mean you need to water. And even where there are no restrictions we should all be doing our best to conserve water. Reducing the water you give your plants will also save your time, effort and money and you will still have a healthy garden.
