Self Watering Probes are a simple and effective way of watering
your plants while you are on vacation. Just soak them in water
for a couple of minutes to prepare the tips, then insert the
probes into the soil of your potted plants and place the hose
ends in a water reservoir nearby. The water will be slowly
emitted through the ceramic cones, automatically watering your
plants without the need to set timers or worry about electronic
devices being turned on while you are away
