It is an irrigation system based on watering plants on demand adapted to plastic bottles. Almost any standard plastic bottle between 0.25 liters and 2 liters can be used with Blumat Easy. Simply fill the bottle, install the dripper and make a small hole at the end opposite the dripper to prevent a vacuum. The Blumat Easy is capable of supplying 200 ml of water per day and the XL up to 300 ml.
