Top 16.5" / Bottom 10.5" - 15"High - 2.25 Gal

Maintain healthy container gardens using a Self-Watering Planter Insert. This 16.5 inch Round model features a self-fill tank, water wick and moisture level monitor. The fill hole is large enough to fit a garden hose and the vacuum-sensor technology conserves water by only allowing the plant to drink when soil begins to dry. Water-smart planter inserts also minimize evaporation off the top layer of soil and catch rainwater to refill the tank while draining any excess runoff. Another perk is that self-watering planter tanks do not sweat, so terra cotta pots won't have any unsightly water stains. This size is designed for use in a 22 inch garden container and will extend watering intervals up to 4 times beyond regular hand-watering schedules. Streamline your watering and watch flower arrangements thrive with this smart self-watering irrigation system.

Additional Self Watering Insert Information

To fill your reservoir, simply remove the stopper plugging the fill hole on the top of the reservoir and pour water in by hand. Replace the stopper when the reservoir is full. The water will flow into the soil through the holes in the bottom of the reservoir. This allows the plants to be watered from the bottom up, the way that nature intended. The reservoir contains a moisture sensor, which will cause a tube to close once it absorbs moisture, preventing your plants from being over-watered. When the plant has used the water in the soil, the sensor will dry, and the tube will open again and the process will repeat.

Drainage Plug

These reservoirs have a built-in overflow drainage plug in the sidewall. If the reservoir will be used outdoors, remove the plug to allow excess water to flow out as necessary. If the reservoir will be used indoors, leave the drainage plug in place, as overflowing should not be an issue. Questions? Email or call us toll free 1-800-896-0978
