Staggered rather than stacked, the five bins on this 44-inch black planter step back one behind the other so no tier shades the one below it. Each bin measures 19.5 by 7.5 by 6 inches and holds up to 22 pounds, which covers a row of herbs, leaf lettuce, or bedding flowers. Bins lift off the frame individually, making soil changes and rinsing quick, and every one pairs drainage holes with a detachable drip tray so you can let excess water run off outdoors or hold humidity indoors. The footprint stays at 23 by 27 inches, small enough for a narrow balcony or a corner beside a doorway. A powder-coated metal frame carries the load at 16 pounds assembled, and the unit bolts together from flat-packed parts with the included manual.
