Blumat Super Long 16" Outdoor Sensors
The Blumat Super Long acts as a regulator and dripper, just like the standard Tropf-Blumat. This one is 16" long though. It senses the moisture at a deeper level which 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. In a very large pot, sometimes it's best to use all 3 sizes to monitor high, medium and low levels. These are also great for trees, big plants and going through the side of a large fabric pot.
