Included: 1/6/12/18/30 x Automatic Watering Spike Features: 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. When using spike, simply fill the ceramic cone with water, cover it and push it into the soil. Then place the supply hose in a nearby sink. Now it will draw water into the pot as the factory needs. When the water in the clay cone is inhaled into dry soil, it will produce a vacuum to inhale more water through the supply hose. This is the perfect choice for watering any indoor plant. It is perfect for those who travel and want to make sure their plants are properly watered. The large planter will require two or more plant fountains.
