GREANER Rectangle Planter 3-Pack Long Window Boxes 16.9x7.48 in Black — Removable Trays & Adjustable Drainage

GREANER 3-pack rectangle planters are long, durable plastic window boxes with removable trays and drainage features designed for indoor and outdoor container gardening.

These compact, rectangular flower boxes (16.9 x 7.48 x 5.5 inches) come in a set of three, each with a detachable water tray. Constructed from UV-stabilized plastic, the planters resist fading and impact while offering elevated feet and multiple drainage options to protect surfaces and support healthy root conditions. They’re made for balconies, windowsills, patios, and small vegetable or flower projects where space and clean watering matter.

How do these planters manage watering and drainage?

Each planter includes a removable tray and elevated feet so excess water can drain away without pooling under the box. The design offers four pre-opened drainage holes and two reserved holes you can activate if needed, giving flexible control over moisture levels.

• Removable tray separates from the planter for easy cleaning and water collection.
• Elevated feet allow air circulation beneath the box to prevent soggy roots.
• Four active drainage holes plus two reserve holes to customize drainage.
• Tray protects windowsills, shelves, and railings from stains and runoff.

What size plants can I grow in these 16.9 x 7.48 inch boxes?

The planter length and depth suit small to medium plants such as herbs, compact vegetables, annuals, and bedding flowers. The internal space supports multiple herb stems or a row of bedding plants, while the depth gives roots room to establish without needing frequent repotting.

• Fits herbs (basil, parsley), small veggies (lettuce, radishes), and compact flowers.
• Depth supports root development for seasonal crops and ornamentals.
• Three identical boxes let you rotate crops or create coordinated plantings.
• Tray allows indoor placement without water damage to shelving or sills.

Are these planters durable enough for outdoor exposure?

Yes. GREANER planters are molded from UV-protected plastic that resists fading, cracking, and impact under typical outdoor conditions. Their moisture-proof, wear-resistant construction makes them suitable for balconies, patios, and other semi-exposed locations.

• UV stabilization reduces color fading from sun exposure.
• Impact-resistant plastic withstands bumps and seasonal handling.
• Moisture-proof material avoids degradation from frequent watering.
• Lightweight design simplifies moving and seasonal storage.

How do these planters make planting and maintenance easier?

The trays, removable design, and pre-formed drainage setup streamline potting up, watering, and cleaning. Three identical boxes let you group plants for coordinated care, and the lightweight plastic eases repositioning for sun, shade, or seasonal decor changes.

• Removable trays speed up emptying and cleaning tasks.
• Lightweight construction simplifies filling and relocating boxes.
• Uniform size helps plan and rotate plantings efficiently.
• Two reserved drainage holes provide optional customization for different plants.
