Take the guess work out of watering your plants with the self-watering system built into these attractive planters. To avoid damaging plant roots from over-watering, these innovative planters feature a 'next generation' water reservoir in the base. Water is wicked upwards into the soil around the plant roots with the included Vermiculite bag assisting the process. A filler tube feeds the water reservoir and also houses a water level gauge for at-a-glance checks. Adjustable mounting brackets are included, allowing the planters to be hung from a balcony rail. Each planter consists of two containers: the upper for soil and the lower for water. The easy-to-read gauge indicates when the reservoir needs refilling. Made from 95% recycled plastics, these planters are suitable for indoor or outdoor use. Specifications: Dimensions: H:17.0 x W:21.0 x D:39.0 cm. Colour: Anthracite. Guarantee: 2 Years.
