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 (Drip-Blumat) 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. Every plant, every container or group of plants requires at least 1 Tropf-Blumat adjusted to the individual needs of the plant. Larger containers or surfaces require longer or more than one sensor. All Tropf-Blumats are connected using one supply tube, this allows for flexibility in the layout and is changeable at any time.
Blumat Sensors use the 3MM drip tubing and come with one 8MM to 3MM reducer tee for connecting your sensor to the 8MM water supply tubing.
Makes watering a breeze
