When needed water is dripping out of the end of the dripping hose annexed at the Tropf-Blumat. To launch the Tropf-Blumat on larger areas more effectively you use the drip devider. Up to 5 drip devider can be installed in one row, connected by 20 cm long parts of the dripping hose. At the end of this you install an end drip devider. You should not chose this possibility when you're connected to water tank. The pressure is not high enough. But you can use a water tab for this.

Now, when the soil becomes dry, the desiccating pottery sensor creates a certain section power for the physical wetness balance, that releases the watering. As soon as the soil is wet enough, the suction power stops and the watering ends just by itself.
You will find find all information about the Blumat-watering system in the annexed brochure. You can download it here (only available in German).
