Trolmaster Water Content Sensor 3 w/ Splitter Cable Set (WCS-3)

See your root-zone moisture as a clear percentage

The Trolmaster WCS-3 Water Content Sensor measures the moisture level of your growing medium in real time, displaying it as a straightforward water content percentage (WC%) so you can dial in irrigation from data rather than guesswork. It integrates directly with Aqua-X, Aqua-X Plus, Aqua-X Pro, Hydro-X Pro and Tent-X controllers, showing live readings on its built-in LCD and through the TM+ Pro app. An ultra-slim probe slides into soil or coco without disturbing the root zone, and sensors can be daisy-chained to cover larger grows. The supplied splitter cable set makes connection straightforward.

Key Benefits

• Moisture shown as WC% for precise, at-a-glance irrigation control
• Broad compatibility with Aqua-X, Aqua-X Plus, Aqua-X Pro, Hydro-X Pro and Tent-X
• Built-in LCD plus TM+ Pro app monitoring with historical trend tracking
• Ultra-slim probe for easy insertion into soil or coco
• Daisy-chain capability for multiple sensors across larger setups
• Splitter cable set included for quick, tidy connection

Guessing at watering in soil or coco?

Incorrect watering is one of the most common problems in indoor growing. Overwatering suffocates roots and slows growth, while underwatering stresses plants, limits nutrient uptake and cuts yield. Live WC% readings give direct visibility of root-zone moisture, so irrigation cycles in drip and automated systems can be tuned to keep coco or soil in the ideal band for strong roots and dense flower.

How to Use

• Insert the WCS-3 probe into the growing medium near the plant's root zone.
• Connect the sensor to a compatible Trolmaster controller using the included splitter cable.
• Power on the controller and allow the sensor to initialise.
• Read the current water content on the sensor's built-in LCD.
• Monitor readings through the controller interface or the TM+ Pro app.
• Configure moisture alarms or irrigation adjustments based on the WC% data.
