Self-watering probes are a simple and effective way to water plants during a holiday.
Just immerse them in the water for a few minutes to prepare the tip, then insert the probe into the soil of the potted plant and place the ends of the hose in a nearby pool.
Water will flow slowly through the ceramic cone, watering the plants automatically, without setting a timer, and without having to worry about the electronic device turning on when you leave.
This high quality European design, using Chinese plant drinking water, without power, automatically keeps the soil of potted plants at optimum moisture levels.
