How the CWI Classic Works
The CWI
Classic reservoir is filled
every 2 to 3 weeks (2-4 weeks interior, 1-3 weeks exterior). The fill
hole is closed with a stopper, creating a vacuum-tight closed reservoir.
When the soil is dry
(indicating 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 up through the soil,
irrigating the plant.
As the soil becomes
moist, the sensor (planted in the soil 1/3 to 1/2 way down the
container) 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.
