CWM Modular™ is a versatile container irrigation system designed for use in any large planter, freestanding or otherwise. The hand-filled reservoir system can go 2-3 weeks between fillings. It utilizes Planter Technology’s exclusive vacuum-sensor system to precisely monitor the soil moisture in the container, giving plants exactly the amount of water they need (see below). The CWM provides optimal flexibility for use in virtually any shape planter, will not interfere with lighting or other electrical connections, and requires no plumbing. With the use of a overflow drainage adapter CWM can control run-off of irrigation water – no more overflowing saucers or stained pavers.

The CWM system consists of several oversize reservoir modules connected together with flexible tubing. It is filled by hand every 2-3 weeks. The fill hole is closed with our exclusive tamper-resistant cap, creating an airtight seal. The upper connecting tubes allow air and vacuum to be transmitted to all modules, the lower connecting tube passes water between the units.

When the soil is dry, the porous moisture sensor allows air to pass through the tube into the reservoir, permitting water to flow into the soil through the holes in the bottom of the "cup" in the CWM. This water wicks up through the soil, watering the plant.

Overflow drainage adapter prevents discharge of irrigation water

As the soil becomes moist, the sensor (planted _ to 1/3 way down in the container) absorbs water. It closes like a valve, preventing air from passing through the tube. A vacuum is created above the reservoir, preventing further watering until the soil dries again.

The overflow drainage adapter allows excess water that builds up (typically rainwater) to escape without disrupting the system. Underplantings, after a short acclimation period, typically may be watered on the same cycle as the primary planting.

Components of the CWM™ Modular

Fill Module – An adjustable height fill tube allows use of a garden hose or watering wand. One fill module is required in each system.
Sensor Module – The "brains" of the CWM, one unit is needed in each system. Precisely controls water provided to the plant based upon the soil moisture level.
Secondary Module – Intermediate units hold irrigation water. Quantity depends upon size and requirements of planter. Up to 4 units for each system.
Extension Module – A flat module for very large containers. Connected to the front of a CWM.
Connections – Braided flexible PVC tubing and quick-snap nylon hose clamps provide a reliable seal between each module.
Overflow Drainage Adapter – Sealed over each drainage hole in the planter to keep irrigation water in, allow rainwater out.

Specification Guidelines

1. Each system needs one fill module and one sensor module. For solo units, these are combined (use the configuration code "MS").
2. One fill module and one sensor module can support up to 4 secondary modules. For containers where more are required, break into two separate systems.
3. Modules in system must be the same height. Otherwise shapes and sizes may be mixed where needed.

BPVC-75 Reinforced tubing for connections
AC-75 Nylon quick-snap clamps for all connections
F-7590 Plastic elbow connector for square, CRT Configurations.

BG25P BioGuard fabric to keep roots from growing into reservoir. One per "cup"
P-75 Plug for end units – connection.
