Oliz Window Box Planters 6-Pack 13.8" White — Self-Watering Rectangular Planters with Trays

Oliz Window Box Planter 6-pack are 13.8-inch self-watering rectangular pots with built-in reservoirs, cotton wick irrigation, drainage holes and matching trays for hassle-free herbs, flowers and small vegetables.

These six white Oliz planters combine a 1L water reservoir with an absorbent cotton rope system and bottom air/drainage holes to reduce watering frequency while protecting roots. Each planter measures approximately 13.8" long x 6.3" wide x 5.9" high and is made from thickened polypropylene for outdoor resistance and long-term durability. The set is designed to fit windowsills, balconies, shelves and small garden areas where a compact, tidy planting solution is needed.

How does the self-watering system work?

The Oliz planters use a water reservoir plus an absorbent cotton wick that transfers moisture to the root zone by capillary action. This lets soil draw water as required, moderating soil moisture and reducing overwatering or underwatering between refills. Bottom air holes and drainage channels also help prevent root rot by improving circulation.

• About 1 liter reservoir capacity per pot, feeding plants up to ~10 days depending on conditions
• Cotton wick connects reservoir to soil for consistent moisture delivery
• Multiple bottom drainage and air holes to keep roots aerated and prevent waterlogging

Will these planters survive outdoor exposure and heavy use?

Yes — the Oliz products are molded from reinforced PP plastic and intentionally thickened to resist wear, UV exposure and occasional knocks. The manufacturer states a load-bearing capacity up to 300 kg (660 lb), which indicates solid construction suitable for filled soil and several pots side-by-side. They’re built for years of use on balconies and patios with routine cleaning.

• Durable, thickened polypropylene resists sunlight and weathering
• High weight tolerance for soil, plants and accessories
• Easy to clean; trays catch runoff and keep surfaces tidy

What kinds of plants grow best in these 13.8" window boxes?

The size and self-watering design make these planters ideal for compact edible and ornamental plants. Use them for culinary herbs, salad greens, compact vegetables, succulents, and small flowering varieties that prefer stable moisture. Taller or deep-rooted plants are less suitable unless pruned or grown in larger containers.

• Herbs: basil, parsley, mint, chives, thyme
• Vegetables: baby lettuce, microgreens, small pepper or cherry tomato varieties (monitor roots)
• Ornamentals: small annuals, succulents, ferns and trailing plants

How do I set up and maintain the Oliz self-watering pots?

Setup is straightforward: place the tray, insert the pot with wick into the reservoir, add potting mix and plant, then fill the reservoir. Refill the reservoir when the water level indicator or reservoir run-out occurs — typically every week to ten days under normal indoor conditions. Periodically flush the reservoir and clean the tray to prevent buildup and pests.

• Assemble wick into reservoir, fill with potting mix and plant
• Top up reservoir every 7–10 days depending on heat and plant size
• Clean trays and check drainage holes seasonally
