Blumat Maxi Automatic Watering Carrot (Pair)

The Tropf-Blumat Maxi acts as a regulator and dripper, just like the standard Tropf-Blumat. This one is 9 inches long though. You put it in the ground 6 - 7.5 inches so it senses the moisture at a deeper level. This is important when your plants get bigger because the regular Blumat sensor might turn the water off too soon. And this one might turn it off too soon if your plant still has surface roots. Some growers use both - especially if they are growing in coco or a hydroponic system.

The Tropf-Blumat Maxi is a sensor that supplies plants with drips of water via thin tubing. As the soil dries, its natural suction power triggers the opening of the Tropf Blumat allowing the water to flow. When the soil is sufficiently moist, the Tropf Blumat automatically stops. The system functions fully automatically.

  • Automatically waters individual plants, and only when needed. 
  • Connects directly to your hose tap or rain barrel. 
  • Easily installed with a pair of scissors
  • Inexpensive and works for years
  • Ideal for small or larger grow areas
  • Silent - makes no noise

The Process

Water is sucked out of the ceramic sensor through the suction force of the dry earth. Suction tension develops in the Tropf-Blumat, the flexible membrane is pulled downwards, thereby allowing the passage of water, the drip tube begins dripping. If the earth is moist enough, then the subpressure in the sensor causes the water to be sucked back into the cone, the membrane returns to its original position and squeezes the drip tube closed with a rod, the passage of water is stopped. The point at which the valve closes is set with an adjusting knob. This determines when the drip tube is closed and by which suction tension (i.e. by which degree of dryness) the watering should begin.

Tropf-Blumat is an intelligent watering system, enabling the plants to take care of themselves. Watering occurs only in amounts that the plants actually need, not just as a back-up during vacation periods, rather throughout the growing season. The self-regulating sensor uses water pressure to control a slow, low dosage dripping, without electricity or use of an automatic dispenser.


Customizing for individual plant sizes and variable system requirements is possible at all times. This opens up a wide spectrum of possible uses- from balcony boxes, to tub plantings on a patio or in a sunroom, to smaller bed plantings, or solitary bushes in the garden or even tomato plants in a small greenhouse.
