Automatic irrigation system for indoor plants. Simple, safe, and easy to use. With the Blumat Classic the plants get exactly the water they need since this dropper works on demand. The water is absorbed through a small plastic tube and is led to the ceramic cone buried in the pot. The cone exudes water when the plant asks for it. The Classic can supply 75 ml per day and the Classic XL is for plants with higher water needs and supplies up to 125 ml per day.
