The CWC container irrigation insert is a self-watering system designed to be dropped into tapered round and square decorative pots. 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). The moisture control, when combined with sub-irrigation (watering from the bottom) makes the CWC the most water-efficient of all irrigation systems.
Rotationally molded Linear Low-Density Polyethylene material
Each insert may be used in either exterior or interior applications. A drain on the side will allow excess rainwater or moisture to overflow. The threaded hole may be filled with the included plug to prevent drainage indoors, or if the pot isn’t exposed to the rain.
CWC Classic inserts are typically used in tapered containers. Stage up under the bottom of the CWC Classic insert with foam, gravel, sand, or any other non-porous space filling material. The lip of the insert should be approximately 1″ below the rim of the pot.
CWC Classic container irrigation inserts are inventory items, and small quantities typically ship within 3-5 days from order. Larger quantities may take up to 2-3 weeks.
CWC Container Irrigation inserts are delivered with a standard fill hole plug for normal use. Use our Tamper Resistant Stopper in high-traffic locations to prevent removal.
