This self-watering system ensures that your plants are well looked after, even when you're not at home. The system draws water from the integrated reservoir through a natural siphon action, without the need for electricity or batteries. Alongside the reservoir with a capacity of 4.4 litres, the set also includes four porous ceramic cones and an 83 centimetre siphon hose, which makes it possible to supply water to several indoor plants in one area. The water supply can be regulated by placing the cones in relation to the height of the reservoir. So you can ensure that your plants remain optimally hydrated even while you are away.
