Easily keep your plants and flowers watered with this incredible window box drip system. The Oasis self-watering kit will automatically handle watering planters. This window box drip system is easy to setup and allows you to select 10, 20, 30, or 40 day cycles. This system can automatically handle watering planters for up to 20 plants. The LED light along the programming panel will indicate when the battery is low and when the Oasis self-watering kit is in use. An isolated tank will prevent condensation and rubber footing prevents scratching surfaces and the sliding of the tank. This complete window box drip system will operate on a single 9V battery.
