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 few 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 spike is used by, just filling the ceramic cone with water, putting the cap on and push the cone into the soil. Then place the supply hose in a nearby container of water.
It will now draw water into the pot as the plant needs it. As the water in the clay cone is drawn into the dry soil, it creates a vacuum that pulls more water in through the supply hose.
