Function

This is how it works

The Tropf-Blumat is filled with water. This water is not used for watering but for control. If the soil gets dry, the Tropf-Blumat releases a bit of water onto the soil. The pressure goes down inside as a result and a valve opens. Once the soil is moist enough, the water is drawn back into the Tropf-Blumat through the clay cone and the valve closes. A simple principle of physics but highly effective and reliably for many years.
