Oliz Window Box Planter 6-Pack 13.8" Self-Watering Rectangle Pots with Reservoirs & Trays — Green, Durable PP for Herbs & Flowers

Oliz Window Box Planter 6-Pack are 13.8-inch rectangular self-watering pots with built-in reservoirs, wicking ropes, drainage and matching trays for easy indoor and outdoor planting.

These six matching planters are designed to sit on windowsills, balconies, shelves or tabletops and simplify growing herbs, vegetables, flowers and small decorative plants. Each pot holds a generous planting area while concealing a water tank beneath the soil that feeds your plants through an absorbent cotton wick. Built from thickened polypropylene for long-term outdoor exposure, the boxes combine practical irrigation with a clean, minimalist look that complements modern interiors and small-space gardens.

How does the self-watering system keep plants hydrated?

Each planter includes a hidden reservoir that stores about 1 liter of water and an absorbent cotton rope that draws moisture up into the potting soil. That capillary action supplies a steady, measurable water source so plants receive moisture without frequent surface watering.

• Approximately 1L reservoir per pot—supports up to 10 days of hydration depending on plant type and conditions.
• Absorbent cotton wick links reservoir to soil for continuous moisture transfer.
• Visible fill access makes refilling quick and simple without disturbing roots.

Will these planters prevent overwatering or root rot?

Oliz planters are engineered with multiple drainage and air holes in the lower chamber to avoid waterlogging and improve aeration. Excess water drains away from the root zone and the integrated tray collects runoff, making it easier to manage moisture levels.

• Bottom drainage holes allow excess water to escape the planting area.
• Air holes increase circulation around roots to reduce stagnation.
• Included trays catch overflow and protect surfaces from stains.

How durable and weather-resistant are these window boxes?

Made from thickened PP plastic, each Oliz planter is built to stand up to sun, wind and outdoor use for many seasons. The material is wear-resistant and strong—tested to carry heavy loads—so you can use the boxes outdoors on a balcony or indoors on a sunny sill with confidence.

• Thickened polypropylene construction for lasting strength and UV resilience.
• Rated to support heavy loads, suitable for dense soil mixes and decorative stones.
• Suitable for indoor or outdoor placement—resists fading and cracking from sun exposure.

What plants and situations are these planters best for?

The shape and size of these rectangular pots make them versatile for herbs, leafy greens, compact flowers and multiple small succulents. Their compact footprint and matching aesthetic make them ideal for organizing a string of planters along a windowsill or outfitting a small balcony herb garden.

• Perfect for herbs (basil, thyme, parsley), small salad greens, and flowers like pansies or petunias.
• Works well for succulents, ferns and decorative foliage when drainage is managed.
• Great for staged arrays—six identical pots create a cohesive, tidy display.

Who is this for: The Oliz 6-pack window box planters suit busy plant parents, apartment gardeners, and anyone who wants an attractive, low-maintenance planting solution. If you need reliable watering between trips, a neat row of herb pots for cooking, or a durable set of planters that fit narrow ledges and balconies, these boxes offer an easy, long-lasting option.
