The Blumat Tropf Maxi Sensor is a longer (9″ end to end) “carrot” sensors, to adequately water plants in deeper pots of 30 cm or more. The sensor includes a short piece of 3mm Blumat drip tube and a 8-8-3mm T-Piece that will fit into the 8mm Blumat water supply line. It works in the same way as the standard 5″Blumat Tropf sensors, but will remain in open until a deeper watering has occurred, read more below…

The Blumat Tropf system works by using gravity and the capillary interaction between the soil and the orange Blumat clay “carrot” cones. When the soil or substrate is dry, it will create a suction inside the water filled cone tubes – opening the diaphragm at the top of the carrot and allowing water to drip from the tubing. Once the soil around the clay cone becomes moist, this suction will cease and close the diaphragm again.

This allows for each individual pot to be watered automatically only when needed, and a single Tropf system can have up to 500* watering points ! The “carrot” does the thinking for you ! 


Whether a person can use a mineral nutrient solution for feeding in conjunction with the Blumat system is debatable – as the small diameter pipping may easily clog up over time with normal salt build-ups and nutrient calcification. A flushing and rinsing agent like Flash Clean may have to be used periodically to dissolve any nutrient build-up inside the piping and/or clay cone “carrots”.  An alternative would be to top-feed with your favorite nutrient range as needed and to rely on the Blumat system for regular watering in between feedings.
