Question about Gardena Balcony Watering

I have taken an optically matching flower pot in rattan look that holds 25 litres and will last for some time. I think there is enough choice in the colour and size of containers that will also fit the balcony. In my case, I simply put a matching wooden plate on top where a small flower pot decorates the whole thing visually.

I use a Samla box from IKEA. They come in all sizes, are cheap and you can see from the outside how much water is still inside. With a suitable lid, the evaporation losses are reduced and no dirt flies in. For our holidays, the 65-litre box should be sufficient.
