Our 33.5” PlanterWell Reservoir for Tapered or Rectangular Window Boxes will keep your window boxes hydrated while preventing root rot. This plastic water reservoir is constructed with tabs at the bottom that allow excess water to drain through the window boxes’ drainage holes. Water wicks up and into the plant as needed through the inlet tube, keeping the soil hydrated without becoming over watered. A large water reservoir that holds approximately 1.6 gallons of water, it is ideal for keeping larger window boxes watered and happy while adding days and even weeks between watering sessions.
