Use

Deciding how many Tropf-Blumat are necessary

For watering planter boxes, use the rule of thumb: 4 drip locations (Tropf-Blumat) per 100 cm box length (box width- 20 cm), 3 drippers for 80 cm. For wider troughs (such as 100x40 cm), usually 6-7 Tropf-Blumat are enough, depending on the size of the plants – also see bed plantings.
For watering in pots, every plant / every pot should have 1 Tropf-Blumat. According to the pot size, 1 Tropf-Blumat is enough for pots up to ca. 20 cm in diameter, for pots up to 40 cm use 2 Tropf-Blumat, up to 50 cm 3 Tropf-Blumat.
The size of the plant is also an important factor and sometimes the needs of a particular plant species plays a role when deciding on the number of Tropf-Blumat needed. Large Containers such as planting tubs, for example, should often have fewer drippers in order to avoid overwatering.
For bed plantings, 2 plants (the size of typical summer flowers such as geraniums)  require 1 Tropf-Blumat (plant spacing ca. 20-22 cm), when planted closer together (about 15 cm), 1 Tropf-Blumat is enough for a group of 3 plants.

Extras in the PLUS-Set:

The additional fittings make it possible to use chains of drippers for watering, the water supply tubing can be branched repeatedly, it can also be shut-off using the stop valve, the dripper tubing can be branched using Mini-Branchers – advantageous when multiple drippers per tub are desired -, or also sealed with 3 mm-sleeves. The additional dripper tubing allows for a movable connection for tubs which are not able to be placed directly by the water supply tubing. Chains of drippers are also practical for bed plantings.

Connection to tap water

The required pressure reducer fits a standard water faucet with  ¾ inch outer threading. The water faucet must be kept constantly open for operation of the system. If the water tap is to be used for a garden hose in addition, then it is practical to use an optional 2-Way-Branch Connector, this allows for the watering functions (hose or Tropf-Blumat) to each be used separately.
The pressure reducer sets the pressure at 1 (0.8) bar, the pressure from the water source should not exceed 6 bar. It is also possible to connect to a house tap with less upstream pressure. For normal upstream pressure of 4-5 bar, the pressure reducer can handle about 250 Tropf-Blumat units over a length of 60 m.
It is important, that the pressure reducer be stored over winter protected from frost, or for the purpose of winter operation, that the water connection is located in a frost-free cellar.

Tubing Installation

The 8 mm-water supply tubing can be placed alongside the bottom of the containers to be watered or also somewhat further away, for example, in order to hide the tubing under an edge (depending upon the length of the tubing). In this case, the dripper tubing extends upwards to the pots or tubs. For each desired Tropf-Blumat location, the tubing is cut and a t-connector is inserted into the two ends of tubing ( for the last Tropf-Blumat at the end of the tubing, use a end piece instead of a t-connector).
The tubing can be branched as desired, also there can be some variation in elevation within the layout, for example, from the point of the faucet upwards max. 4-(6) m and downwards ca. 2-(3) m.
Drippers and water supply tubing can be mounted using support pins which are an accessory to the  system. The support pins allow the drippers to be mounted above the soil level, thus allowing them to be more easily controlled. An occasional control is recommended - see Dripper Chain.  Drip tubing should not be longer than 150 cm, also here, an occasional control with flushing is recommended.
The water supply tubing can also be mounted using any wire fasteners or nail clamps.
 
Function

System

"Tropf-Blumat" (Tropf = Drip) works using pressure as its basis, it requires a minimum pressure for the correct functioning of the watering head and to avoid cloggage.
The Tropf-Blumat is the heart piece of the entire system and acts as a moisture sensor and dripper at the same time. Every dripper location is therefore sensor controlled according to the tensiometer principle. Also included in the system are fittings to connect the tubing.

Procedure

Fill the Tropf-Blumat with water (part of the sensor function only!) – see Directions for Use  – and insert into moist soil. As the soil becomes drier, water is sucked out of the feeler which is a porous clay cone. This creates a sub pressure (partial vacuum). As the pressure develops, a membrane in the watering head is released (before then it is squeezed together), opening the thin dripper tubing; the tubing begins slowly to drip. The water seeps through the soil once again to the clay cone, causing a lessening of the sub pressure, the valve closes; the dripping slowly stops.

Adjusting

The Tropf-Blumat is adjusted using the brown knob; it should be set so that when the soil is optimally wet, the dripper has just stopped dripping. When first using, the sensor requires a certain settling period. Therefore, adjusting should be carried out only after a day of use. The general recommended adjustments are described in the Directions for Use or in our Recommended Settings. It is important that the adjustment is correct from the beginning! 

Maintenance

The water being used must be clean (there is no filter in the system), it can contain completely water soluable fertilizer. It is recommended to treat water that is extremely hard (over ca. 30°dH) by softening or to use rainwater, if possible. Light lime deposits in the tubing can be removed by rubbing. 
The water inside the sensor should be occasionally checked. However, in general, the water will not need to be topped off during the watering period. Under certain conditions, winter operation is also possible.
