Self-Watering Windowsill Planter Box with Water Level Indicator

This sleek self-watering planter box makes indoor gardening easier in any small space. The outer water basin holds up to about 1400 ml of water, while cotton wicks in the inner planting basket slowly draw moisture up to the roots. You water less often, and plants stay evenly hydrated without soggy soil.

Key features:

• Long rectangular 17 in planter, ideal for windowsills, shelves, and narrow ledges

• Double-layer design with separate water basin and ventilated planting basket

• Self-watering system using absorbent cotton ropes to prevent dry-out

• Built-in water level window to see when it is time to refill at a glance

• Side outlet port for easy draining and protection from heavy rain outdoors

The minimalist white-and-gray Nordic look fits easily with modern décor. Use this planter for herbs in the kitchen, flowering plants in the living room, or succulents by a bright window. It is a smart choice for travelers and busy plant lovers who want healthier plants with less daily care.
