The Tropf-Blumat (Drip-Blumat) is a sensor that supplies plants with drips of water via thin tubing. It begins to drip automatically when the soil is dry and stops dripping when an adequate moisture level is reached. This process requires the presence of water pressure; this can be produced either by having a mains connection or by using an elevated water tank.

Every plant, every container or group of plants requires at least 1 Tropf-Blumat adjusted to the individual needs of the plant. Larger containers or surfaces require longer or more than one sensor. All Tropf-Blumats are connected using one supply tube, this allows for flexibility in the layout and is changeable at any time.
