When functioning correctly, the dispensed water is drawn in through the tube. The water level in the Blumat Classic remains virtually unchanged. Keep the water container topped up. If the water container is empty, the Blumat will also have to be refilled.
Long-term watering: It is best to use opaque containers as this prevents algae growth. In addition, water the plants every 4-6 weeks with a watering can.
Maintenance: Blumat will last longer if it is thoroughly cleaned once a year. Open the Blumat and lay both parts in warm water for about five minutes. Then press the cap on firmly several times under water to flush any impurities out of the tube. Clean inside the cone with a small brush and sand down the outside with sandpaper.
Fertiliser: You can easily add liquid fertiliser by pouring some into the water container.
