Not every balcony has an immediately accessible water connection - especially since this should not be left open when you are away for a few days or even weeks. The risk of water damage is just too high. Fortunately, however, there are a number of irrigation systems that work without a water connection.
If you don't want to run back and forth with the watering can umpteen times, you can set up an irrigation system
You do not need a water connection for these systems
Each of the systems listed here is based on the proven principle that the plant draws water from a storage container. This water tank can be small or large, installed directly in the pot or located outside and connected to the planter with a hose.
Planters with water reservoir
Anyone who regularly goes away for a few days should place their balcony plants in a planter with a water reservoir from the outset. Although these are a bit more expensive to buy, they save you regular watering - and reliably supply your plants if you go away for the weekend or even for a week.
PET or glass bottles
A well-known and proven DIY method of watering potted and tub plants is using PET or glass bottles that are filled with water and placed upside down directly in the planter.
Irrigation Cone/Ball
This method works better if you screw a clay or plastic watering cone onto the bottle beforehand. Glass watering balls work on the same principle, but of course they look prettier.
high tank
High tank systems, in which a larger vessel is filled with water and placed above the planters to be watered, are also very practical. The elevated tank is connected to these via thin hoses, with the water running slowly and evenly into the pots and boxes due to gravity and the resulting hydrostatic pressure.
tips
With a battery-operated pump and a timer, you can perfect the high tank system and adapt it better to the needs of the plants.
