Window Planter Boxes 17 Inches

Key points

For apartment gardeners, small patios, or anyone trying to make a windowsill useful, this set offers a way to group plants without taking up the footprint of several separate pots.

You get eight rectangular plastic planters, each listed at 17 x 6.7 x 6 inches, in light gray. Drainage holes and trays are included, so excess water has somewhere to go instead of sitting around the roots.

The shape suits herbs, flowers, and smaller foliage plants for indoor or outdoor use. Keep in mind that these are planting containers, not a mounting system: no brackets or attachment method are specified, so plan to place them on a stable sill, shelf, or other suitable surface.

Best use cases

These boxes make sense when you want a continuous row of plants along a broad windowsill or need several containers that look consistent. For example, you could keep herbs in one box near a kitchen window and use another for flowers, rather than scattering mismatched pots across the sill. The set also gives you the option to spread the planters around different spots instead of using all eight together.

On the spec sheet, the 6-inch depth is a useful fit check before buying: measure your sill or shelf, and consider the root space your chosen plants need. A row of individual round pots may be easier to rearrange one at a time, these rectangular boxes suit buyers who prefer a tidier, grouped display. They’re less suited to plants that need deeper containers or to narrow ledges that can’t accommodate the stated dimensions.

Tips for day-to-day use

Place each planter where it can sit securely, then use the tray to catch runoff after watering. The drainage holes help excess water escape, but they don’t remove the need to monitor moisture, avoid leaving standing water in a tray for long periods. If the boxes are outdoors, choose a spot where you can reach them comfortably for watering and harvesting.

Before filling them, check that the full 17-inch length and 6.7-inch width fit the intended surface. A quick measurement matters more than the light-gray finish if the sill is tight. Because the containers are plastic, they offer a different feel from heavier ceramic pots, though the listing doesn’t give a weight or details about how they perform in specific weather conditions.

Questions before you buy

Are these planters for indoor or outdoor use? They’re described for both settings, including windowsills and garden areas. The listing doesn’t specify a particular mounting method, so use a stable surface rather than assuming they attach to a window or fence.

Do they have drainage? Yes. The boxes have drainage holes and come with trays to catch excess water. The exact number of trays isn’t stated separately.

What can I grow in them? The listed uses include herbs, flowers, foliage, grass, cacti, succulents, and ferns. Match the plant to the 6-inch container depth and the space available where you plan to place it.

Should you buy it?

It makes sense if you want several matching, rectangular containers for herbs or flowers and have a surface wide enough for their listed dimensions. The eight-box set is also more practical than buying a single planter when you’re planning a repeated display across a windowsill or several spots around the home.

Not the best choice if you need planters that come with a confirmed mounting system, have a narrow ledge, or need more depth for your plants. The listing gives the size and basic drainage setup, but not details such as weight, tray count, or specific weather-performance testing. If those points affect where you’ll use them, factor them in before choosing.
