How the Controlled Watering System (CWS™) Balances Moisture and Oxygen
When the soil is dry (the plant needs water), the moisture sensor allows
air to pass through the tube into the reservoir, allowing water to flow
into the container from the bottom. The water wicks through the soil,
irrigating the plant.
As the soil becomes moist, the sensor absorbs water. When wet, it
acts like a valve, blocking the flow of air through the tube. A vacuum
is created above the reservoir, preventing further watering until the
soil begins to dry again.
- CWI™ Features
- Vacuum-sensor technology to balance moisture and oxygen levels in the soil.
- Larger fill hole is recessed to be less noticeable.
- Narrow wall design drops into most decorative containers.
- BioGuard Squares (optional) prevent roots from growing into the water supply.
- New simplified water inlet area is designed to eliminate clogging - no parts to change, no need to remove plant.
- The largest water reservoir of any sub-irrigation system allowing up to 4 weeks between refilling.
