The Blumat Tropf Maxi Sensor 2 Pack includes two longer (9″ end to end) “carrot” sensors, to adequately water plants in deeper pots of 30 cm or more. They work in the same way as the standard 5″Blumat Tropf sensors, but will remain in open until a deeper watering has occurred.
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 !
Please note: The water tank must be at least 0.5 m higher than the Blumat Tropf system for every 5 m of tube but no more than 14 metres higher.
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 FlashClean 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.
Adding a Blumat Tropf Maxi Sensor 2 Pack to your arsenal will take the hassles out of keeping your deep rooted potted plants hydrated and healthy !
