Hydro-X Plus Controller with 4-in-1 Sensor

Step Up to a 7-Inch Touchscreen with Dual Lighting Lines

The TrolMaster HCS-3 Hydro-X Plus controller builds on the HCS-1 with a 7 inch touchscreen display and support for up to 256 lights across dual lighting lines, giving larger single-zone rooms more direct, on-device control.

The included 4-in-1 sensor adds CO2 readings to the standard temperature, humidity, and light measurements, and the controller can monitor for smoke and water leaks in addition to managing your grow equipment.

Key Features & Benefits

• 7-Inch Touchscreen — Larger on-device display for direct scheduling and monitoring.
• Dual Lighting Lines — Supports up to 256 lights split across two independently dimmed lines.
• 4-in-1 Sensor Included — Adds CO2 monitoring alongside temperature, humidity, and light.
• Smoke and Water Detection — Built-in alerts for smoke and water leak conditions.

Who Should Use the HCS-3 Plus Controller

Growers running larger single-zone lighting setups who want a bigger on-device touchscreen and built-in CO2 sensing will benefit from stepping up to the HCS-3.

Choosing Between HCS-1 and HCS-3

If your room needs more than one lighting line, a larger on-device display, or CO2 monitoring out of the box, the HCS-3 is the better starting point than the base HCS-1 controller.
