FillTouch 6 Packs 27 Inch Window Box Planters
This package includes six rectangular window planter boxes, each about 27 inches long. Made from thickened plastic for durability, they feature an elevated bottom design for better drainage and eight drainage holes per box to prevent waterlogging. Best for: users seeking modular, long arrangements in smaller spans or when multiple 27-inch boxes are easier to manage than a single six-foot box. Caution: not a single 6 ft unit, so multiple boxes are needed to cover a continuous run.
Buying Guide
What length should you choose? If you truly need a continuous 6 ft display, aim for a single 6 ft unit or combine multiple connected units. Long boxes reduce seams and create a seamless look, while multiple smaller units offer flexible configurations and easier handling.
What mounting method works best? Steel mounting brackets provide strong support and wobble resistance; ensure your wall material and window framing can bear the weight and mounting hardware. Self-watering designs help with busy schedules but require proper soil depth and reservoir maintenance.
What materials matter? UV-resistant finishes maintain color after sun exposure. Double-wall constructions offer insulation against temperature swings and added durability. Vinyl and high-grade polyethylene are lightweight yet resilient for outdoor use.
What maintenance is expected? Self-watering systems reduce daily watering but still require occasional refills and soil refreshing. Check drainage to prevent root rot, especially in boxes with higher water-holding capacity. Consider color stability if you want lasting curb appeal with minimal upkeep.
