I can finally go away without having to ask the neighbours for help. It's worked flawlessly since day one.
Easy to connect, looks good, and my plants no longer die. I'd buy it again.

Questions & Answers
Frequently asked questions about balcony watering without a water connection
Does the Boum watering system really work without a water connection?
Yes, entirely. All Boum systems come with an integrated water tank. Depending on the model, it holds 32, 35 or 55 litres — so you can water your balcony or terrace completely independently of a tap or water connection. Simply fill the tank, and Boum takes care of the rest.
How long can the watering system run without refilling?
That depends on the tank size, the number of plants and the time of year. As a guide: with a typical balcony setup, the 32 L tank (Bundle S) lasts around 1–2 weeks, the 35 L tank (Bundle M) about 2 weeks, and the 55 L tank (Bundle L) up to 3 weeks. A little less in hot summer weather — but Boum adjusts automatically.
Do I need mains power or a socket for the watering system?
No. The Boum Controller is charged by a built-in solar panel — it needs neither a mains connection nor a socket. This makes the system ideal for balconies and terraces where there is no socket or where cables would get in the way.
How many plants can the automatic watering system water?
The Boum Drip system waters up to 20 pots at the same time with a single controller. Each pot receives exactly the right amount of water through its own dripper — adjusted to the pot size, plant type and weather data.
Is Boum also suitable for watering my plants while I’m on holiday?
Yes — that’s one of the most common reasons customers buy Boum. The system waters fully automatically and adjusts to the weather and temperature. Thanks to the integrated tank, it runs for weeks without intervention. While you’re on holiday, you can keep an eye on the water level via the app or simply let the system run — without a smartphone.
What is the difference between Boum Drip, Boum Pro and Boum Core?
Boum Drip is a drip irrigation system: small drippers deliver water directly into your existing pots. The key difference from other systems: Boum Drip automatically adjusts the amount of water to current weather data and the selected plant type — watering less when it rains or temperatures are cooler, and more in hot weather. This means your plants always receive exactly the right amount.
Boum Pro and Boum Core use wick watering: the plant actively draws water from the water tank through a wick — exactly as much as it needs at that moment. This is the most natural and gentlest method for plants, as overwatering is not possible. It requires Boum’s own pots.
All three systems work without a water connection or mains power and are ideal for balconies, terraces and holidays.
Which pots are suitable for drip irrigation with Boum Drip?
Boum Drip works with virtually any standard pot — whether round, square, small or large. The included drippers can be positioned flexibly in most pot sizes. So you can keep using your existing pots and add Boum Pro or Core pots later.
Does the system also work when it rains — or does it keep watering anyway?
Boum uses current weather data and adjusts watering automatically. If it has rained heavily or rain is forecast, the system pauses or reduces the amount of water — so your plants are neither overwatered nor underwatered.
