CWF Low Bowl Container Irrigation Insert

Low bowls are some of the most maintenance-intense elements in a commercial landscape. The CWF Low Bowl container irrigation is a self-watering system designed to solve this problem. For over 30 years Tournesol’s proven vacuum-sensor watering system has precisely controlled moisture levels in the soil, watering the plant when the soil starts to dry. The oversize reservoir allows for refill intervals up to four times longer than typical hand watering (up to 2-4 weeks for interior plants, 1-2 weeks for exterior). This moisture control, when combined with sub-irrigation (watering from the bottom) makes CWF the most water-efficient of all irrigation for pots & planters.

Features

  •  Extended maintenance intervals

  •  Controls moisture for healthy plants

  •  Built-in overflow drain

  •  For flower bowls and planters

How container irrigation works

Container Irrigation: Self-Contained Insert-Style

Tournesol Siteworks has produced the highest quality of self-watering systems since 1979.The proprietary moisture sensor controls the water released into the soil allowing for the largest water reservoir and the longest interval between watering. For more information,please see individual product details sheets.
1. The key to the system – A micro-porous sensor tube acts as a simple valve. It allows air to pass when the soil is dry, closes when soil is moist.
2. Reservoir is filled through a hole at the top – the amount of water is dependent on the size of the insert.
3. Once full, the reservoir is closed with a rubber stopper, which creates an airtight seal.
4. When the soil is moist (the plant has water), the sensor is closed and a vacuum is created above the water, preventing it from flowing.
5. When the soil dries, air is allowed through the sensor and breaks the vacuum. Water flows into the soil from holes in the bottom, and wicks up into the soil like a sponge.
6. When the roots become moist, the sensor closes and the vacuum is created – stopping the flow until the plant uses the water and the process starts again.
7. When it rains, excess water builds up in the bottom of the insert until it reaches the overflow hole.
