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 refi ll 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.
