2Pcs Easy Use Plant Waterer Automatic Houseplant Spikes Automatische We don't offer color choice. Your order will be sent in colors at random. 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. Using no power source, this high-quality, European-design but made in China plant waterer will automatically keep a potted plant's soil at the optimum moisture level. 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 wate. 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.
