THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are switching to feed-on-demand irrigation because your timer-based cycles leave your substrate too dry when temperatures spike.
  • You are adding root-zone monitoring because you need to see exactly what is happening in the medium instead of relying on manual pot checks.

  • We suggest mapping your sensor placement early, as the daisy-chain setup saves significantly on cable labour and clutter.
  • The data averaging function is the real winner here for smoothing out readings if your emitters have inconsistent flow.

  • Operators who integrated these sensors with their irrigation system report they no longer worry about dry pockets in large-volume pots.
  • Growers who moved to this multi-point setup say they have a much clearer picture of salt build-up compared to single-probe systems.

TrolMaster WCS-9 3-in-1 Substrate Sensor Set (VWC, EC, Temp)

Commercial cultivation demands precision, yet localized variations in substrate can lead to uneven growth and wasted nutrients. The TrolMaster WCS-9 Substrate Sensor Set provides professional growers with high-precision measurements of Volumetric Water Content (VWC), Electrical Conductivity (EC), and Temperature within the root zone. By integrating directly with controllers like the TrolMaster Aqua-X NFS-1, this system enables you to automate irrigation based on real-time substrate data, ensuring a perfect balance for every plant.

What's Included

  • 1 x WCS-9 Sensor Display
  • 1 x WN-9 Sensor Node
  • 1 x 16ft RJ12 Cable Set
  • 1 x T-Splitter

FAQs

How does the WCS-9 handle localized dry spots in the substrate?+

The system utilizes multi-point data aggregation to average readings across the medium. This prevents localized anomalies like dry pockets or water channeling from causing false readings or premature irrigation cycles.

Is this sensor compatible with the original Aqua-X controller?+

Yes, the WCS-9 is fully compatible with the Aqua-X NFS-1 and larger systems like the Aqua-X Plus NFS-3. It connects via the standard RJ12 ports.

How many WCS-9 sets can be daisy-chained together?+

The maximum number of units depends on your specific TrolMaster controller capacity. The daisy-chain architecture allows you to scale root zone monitoring across large facilities without individual cable runs for every sensor.

Does the sensor require manual calibration for different substrates?+

The WCS-9 features a simplified calibration process managed through the TrolMaster app. This allows you to fine-tune accuracy for specific media types, such as rockwool, coco coir, or soil.

Can the WCS-9 trigger automated feeding?+

Yes, when paired with a compatible controller, the VWC data acts as a trigger for "Feed on Demand" irrigation. Pumps can be activated automatically once the substrate moisture drops below your defined threshold.
