This Self-watering Recycled Sky Planter makes modern urban gardening easy and unique. The upside-down planter offers a unique way to display small plants or even grow a few fresh herbs. Perfect for compact spaces. The innovative shape of the self-watering planter conceals an inner water reservoir with a ceramic membrane (the patented Boskke Slo-Flo irrigation system) that slowly feeds the plant water up to over 4 weeks. The recycled sky planter can be used indoors with complete confidence as it has an effective locking disc holding the plant and soil in place, and no excess water to drain away. The Self-watering Recycled Sky Planter is made from 100% recycled polypropylene plastic to protect the environment with zero wastage, and also to make it much lighter. Color: Anthracite.
