Trolmaster Aqua-X Water Content Sensor (WCS-1)

Know exactly how wet your root zone really is

The TrolMaster WCS-1 Water Content Sensor measures the moisture percentage directly inside soil, coco or other growing media and feeds real-time data to the Aqua-X irrigation control system. Instead of watering to a fixed timer and hoping, growers get an actual reading from the root zone to base irrigation on, helping maintain consistent moisture for healthier development and better nutrient uptake. Up to 8 WCS-1 sensors can run on a single Aqua-X controller, so multiple pots or zones across a grow tent or room can be monitored at once, with readings shown on the sensor's LCD, the controller and the TM+ mobile app.

Key Benefits

• Direct water-content readings as a percentage within the growing medium
• Aqua-X integration with live display on the sensor, controller and TM+ app
• Up to 8 sensors per controller for monitoring multiple pots or zones
• Built-in LCD display for a quick on-site check without the app
• Mobile alerts through the TM+ app when moisture drifts
• Better-timed irrigation that avoids both overwatering and excessive dry-back

Not sure if you're overwatering or letting the medium dry out too far?

Incorrect watering is one of the most common indoor-growing problems. Overwatering starves roots of oxygen and slows growth, while letting media dry back too hard stresses plants and knocks back nutrient uptake. With a WCS-1 in each zone you see the real moisture trend rather than guessing from pot weight or a timer, so irrigation cycles can be tuned to what the roots are actually experiencing - building stronger roots and more even growth through veg and flowering.

How to Use

1. Insert the WCS-1 probe into the growing medium near the plant's root zone.
2. Connect the sensor to the Aqua-X irrigation controller.
3. Assign the sensor address with the built-in button if running more than one.
4. Let the system begin measuring water content in real time.
5. Check readings on the sensor display, Aqua-X controller or TM+ app.
6. Adjust irrigation timing based on the moisture data to hold optimal root-zone conditions.
