Oliz Window Box Planters 13.8" 6-Pack Grey — Self-Watering Rectangular Pots with Trays and Drainage

Oliz Window Box Planter 6-pack are 13.8-inch self-watering rectangular pots with built-in reservoirs and trays, designed to keep herbs, flowers and small vegetables hydrated while fitting neatly on windowsills and balconies.

These Oliz planters combine a shallow, modern profile with an internal water-storage system and absorbent wicks so potted plants receive consistent moisture without daily watering. Made from thickened PP plastic the set includes six identical grey boxes and matching trays, each offering a compact footprint for indoor and outdoor use. Drainage and ventilation features reduce the risk of overwatering while the 1L reservoir capacity supports plants for up to ten days between fills.

How does the self-watering system work and keep soil balanced?

Each planter has an internal reservoir beneath the planting chamber and an absorbent cotton rope that wicks water up into the soil as needed. This passive capillary action supplies moisture gradually so roots avoid constant saturation.

• About 1 liter reservoir per pot for extended watering intervals
• Cotton wick connects reservoir to planting soil for steady moisture
• Air holes and drainage points at the bottom improve oxygenation
• Separate tray catches excess water and protects surfaces

Will these planters fit my windowsill or balcony railing?

Each planter measures approximately 13.8" long, 6.3" wide and 5.9" high, a size that suits most standard windowsills, narrow balconies, shelves and kitchen counters. The rectangular form maximizes planting area while remaining compact.

• Low-profile length fits narrow ledges and sills
• 6-pack layout lets you create continuous planting displays
• Lightweight but durable for easy repositioning
• Neutral grey complements indoor and outdoor decor

What kinds of plants thrive in these window boxes?

The shallow, well-drained design is ideal for herbs, small vegetables, succulents, annual flowers and ornamental foliage. Root depth and water needs are best matched to medium- to shallow-rooted species.

• Herbs: basil, parsley, chives, thyme
• Small vegetables: baby lettuce, radishes, green onions
• Ornamentals: petunias, marigolds, small ferns
• Succulents and cacti with careful reservoir management

How durable and low-maintenance are these planters?

Constructed from thickened polypropylene, the Oliz boxes withstand outdoor exposure and heavy loads while remaining low-maintenance. The material resists cracking, UV damage and wear, and the trays simplify cleaning and water management.

• Reinforced PP construction supports heavy pots and long-term use
• Design tolerates sun, wind and seasonal outdoor conditions
• Removable trays and simple reservoirs for easy cleaning
• Minimal assembly — add soil, wick, and water to start
