Oliz 17" Window Box Planter 4-Pack — Self-Watering Rectangular Flower Pots with Trays, White

Oliz 17-inch window box planter set are four self-watering rectangular pots with reservoirs and trays, designed to keep herbs, vegetables and flowers hydrated while fitting narrow windowsills and balconies.

These planters combine a built-in water storage system, absorbent wick, and drainage vents so you can grow multiple small plants without daily watering. Made from thickened polypropylene, each 17 x 5.1 x 6 inch pot is lightweight yet strong, resistant to sun and weather, and includes removable trays for easy cleanup. The set is tailored for indoor and outdoor micro-gardens—herbs, succulents, annuals and small vegetables all fit comfortably.

How does the self-watering system keep plants healthy?

The Oliz window box uses a bottom reservoir that holds roughly one liter of water per pot and an absorbent cotton rope that wicks moisture from the reservoir into the soil. Vent and drainage holes balance air and excess water so roots breathe and avoid rot. Together these features provide steady moisture while reducing overwatering and daily maintenance.

• Approximately 1L water capacity per pot for extended hydration
• Absorbent cotton wick transfers consistent moisture to roots
• Multiple drainage and air holes prevent waterlogging and improve oxygenation
• Removable tray collects runoff for easy draining and cleaning

What sizes and weight can these planters handle?

Each planter measures about 17 inches long, 5.1 inches wide and 6 inches high—long enough for multi-plant arrangements but narrow enough for window ledges. The reinforced PP construction is thickened to support heavy loads without cracking, rated to withstand significant pressure for durable outdoor use. Their low profile works well with shallow-rooted herbs and compact ornamentals.

• 17 x 5.1 x 6 inches fits most window sills and narrow balconies
• Thickened polypropylene body for long-term durability and UV resistance
• Engineered to support heavy soil and multiple plants without bending
• Lightweight for handling but strong enough for outdoor exposure

How easy is planting, refilling, and maintaining these boxes?

Setup is straightforward: place the wick into the soil, add potting mix and plants, then fill the reservoir via the designated fill point. Trays make emptying and moving simple, and the self-watering design reduces how often you need to water manually. Routine upkeep is minimal—top off the reservoir when it drops and refresh soil annually or as needed.

• Simple wick installation connects soil to reservoir for passive watering
• Fill port and removable trays speed refills and cleanup
• Low maintenance—reservoir supplies water for days to weeks depending on conditions
• Suitable for potting mixes, specialty soils for succulents, or herb blends

Where can I use these planters and what plants work best?

Oliz planters suit indoor windowsills, balconies, kitchens, office shelving and outdoor railings when protected. Their slim profile makes them ideal for grouping and creating layered displays. Best choices are herbs, lettuces, compact vegetables, small annuals and succulents that prefer steady but not waterlogged soil.

• Perfect for herbs (basil, parsley, chives), salad greens and compact veggies
• Works for succulents, sedums and small flowering annuals
• Decor-friendly minimalist design complements modern interiors and patios
• Four-pack allows coordinated displays or separate planting zones

Who is this for: The Oliz 17-inch window box planter 4-pack is made for busy gardeners, apartment dwellers, kitchen cooks who want fresh herbs, and anyone wanting low-effort container gardens. If you need durable, space-saving planters that reduce daily watering and look neat on narrow ledges, this set is practical and attractive. It’s also a good fit for people who travel occasionally or prefer a more hands-off approach to small-space gardening.
