Relax with self-watering window boxes! Tapered window box reservoirs fits snugly in the interior of our tapered planter liners and tapered window boxes. Our exclusive design prevents overwatering by allowing excess water added to drip from the overflow drainage holes. If you have a longer garden box you can mix and match reservoir sizes to find the right fitting water supply for your container garden. Tank holds approximately 1.6 gallons of water. This size fits our 36" tapered liners like a glove!
