The Nantucket is a 20 in. square floor planter with a self-watering reservoir that holds 960 oz. of water. It is molded from UV-resistant polyethylene, with a double-wall design that insulates roots and retains moisture. The planter measures 20 in. H x 20 in. W x 20 in. D, weighs 12.8 lb. empty, and holds 1.46 cu. ft. of soil (43.6 qts.). No assembly is required, a fill port plug is included, and the planter carries a 15-year residential warranty (5-year commercial). The 20 in. square footprint suits a porch or entryway, where a pair can be set on either side of a front door. The 960 oz. reservoir and fill port suit hot-summer patio planting, reducing the need for daily watering. At 12.8 lb. empty, it can be carried to its final spot and then filled with soil, which helps when placing it on a deck or balcony. Color: Black. Material: Plastic.
