Boum - Smart solar-powered watering
Featured on TV, in the press and in research.
Now available in-store for the first time at HORNBACH.
How does Boum work?
- Smart controller: The controller acts as the lid of your water tank. Sensors monitor the water level and automatically manage the water supply to your plants.
- Efficient water distribution: Water is distributed to the pots through hoses. The plants draw the water they need upwards through wicks from below – just as in nature.
- Reliable app alerts: The app gives you an overview of all your data. Push alerts also let you know automatically and in good time when you should refill the water or add fertiliser.
Smart
Our smart, solar-powered watering system reliably supplies your plants with water and gives you all the key data.
Sustainable
Our self-regulating wick watering or drip irrigation saves up to 40% water compared with other solutions.
Autonomous
Once set up, the system runs independently in the background on solar power. No water or power connection is needed.
Keep track of everything in the app.
Whether you're on holiday or going about your day, the Boum App keeps you up to date. While the system cares for your plants, all sensor data comes together in the app, complemented by weather and plant data. The app automatically and reliably sends timely push notifications to remind you to refill the water tank or fertilise your plants.
The Boum story
More green balconies without the effort – our story began with this idea from a University of Bern project. Our Boum systems have already helped thousands of customers in Switzerland grow healthy plants.
Along the way, we gathered feedback and developed our idea further to make Boum accessible to everyone. The result: Boum Core. The proven technology stays the same, but the pots are a little smaller and lighter, more compact thanks to a new packaging concept – and much more affordable. And now available in Germany for the first time.

Is Boum Core suitable for beginners?
Yes, absolutely! Boum Core was developed specifically for beginners, but is also perfect for more experienced gardeners. Setup is very simple, and the system waters automatically and reminds you when it's time to fertilise. The app gives you an overview as well as helpful explanations, while our AI gardening assistant Herby and our human support team are always there to help. Nothing stands in the way of a green balcony.
How often does the water tank need refilling?
That depends on several factors: location (sun or shade), plant type, the number of pots per tank and, of course, the weather. Tests have shown that each pot on a balcony or terrace uses around 0.5–0.8 litres per day in midsummer. With two pots connected, the water tank only needs refilling after around three to four weeks. So you can go on holiday without worrying!
Which plants and soil are suitable for the Boum system?
You can generally use soil and plants from your local nursery. What matters is that the plant suits the pot size. We have tested many plants, and you can find recommendations for the different pot sizes on our website and in the Boum App.
Testing allows us to guarantee that the composition of our specially formulated soil is optimally suited to capillary watering in the Boum system:
- Potting soil for balcony and terrace pots
- Houseplant soil for all indoor pots
