Usages:
To keep the soil moisture level as constant as possible, irrigation should
be carried out with short watering cycles and short watering times. This
especially applies to flower boxes on balconies, which have a watering
time of < 5 minutes.
The spread of moisture in the soil after watering or rainfall is rather slow.
In the worst-case scenario it may happen that irrigation and a rain shower
overlap until the required soil moisture is attained.
