CWM Modular Container Irrigation Systems

CWM Modular is a versatile self-watering system designed for use in any large planter, freestanding or otherwise. Reservoir modules are linked together and buried within the pot. The hand-filled reservoir utilizes Tournesol Sitework’s vacuum-sensor system to precisely monitor the soil moisture in the container, giving plants exactly the amount of water they need. The CWM Modular provides optimal flexibility for use in virtually any shape planter, will not interfere with lighting or other electrical connections, and requires no plumbing.   

Features

  •  Extended maintenance intervals

  •  Controls moisture for healthy plants

  •  Modular construction for all size & shape pots

How container irrigation works

Container Irrigation: Modular Style

Connect as many as five modules together and plant in the pot to store incredible amounts of water and reduce maintenance. The CWM™ Modular System includes all parts required for installation, including the modules, connecting tubing, a drainage overflow adapter, and BioGuard root barrier. 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 modules are filled through a hole at the top of a fill pipe, which extends above the soil – the amount of water is dependent on the size and number of the modules. Water flows from the fill module to the others via a tube connecting them at the bottom.
3. Once the modules are full, the fill pipe is closed with a tamper-resistant stopper, which creates an airtight seal (and prevents curious fingers from removing it).
4. When the soil is moist (the plant has water), the sensor tube is closed, and a vacuum is created above the water, preventing it from flowing. The vacuum is shared by a tube connecting the tops of the modules.
5. When the soil dries, air is allowed through the sensor tube and breaks the vacuum. Water flows into the soil from holes in the bottom of each module, 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 container. The modular system includes an overflow drain adapter to be glued in place over the drain hole. Excess water flows out, preventing oversaturation.
