Automatic watering system for indoor plants. Simple, safe and easy to use. With the Blumat Classic, plants get exactly the water they need because this dripper works on demand. The water is absorbed by a small plastic tube and directed to the ceramic cone buried in the pot. The cone exudes water when the plant demands it. The Classic is capable of supplying 75 ml per day and the Classic XL is for plants with higher water needs and supplies up to 125 ml per day.
