The Hydro-X Plus controller is an upgraded version of the Hydro-X controller. It’s a professional-grade single-zone environmental control system that can control your entire grow space.

It has an 18cm LED display monitor and can control an unlimited number of lights, 8 temperature devices, 8 humidity devices, 4 CO2 devices, and 12 programmable timer devices (up to 50 schedules can be created). With incredible flexibility and the expanded product capacity, anyone can now easily customize their own grow room control system for maximum yields. Having multiple control modules also provides the option for the user to create multiple “stages” of temperature and humidity control, which will provide a more stable environment.

The HCS-3 system comes with an MBS-PRO 4-in-1 sensor to measure temperature, humidity, CO2 ppm, and the presence of light. Lighting control has never been easier or more capable. The optional MBS-PAR light sensor can be added to the system. It will automatically adjust light intensity to precisely provide the exact amount of illumination for optimum plant growth. The Hydro-X Plus can also track your DLI levels. Having 2 separate lighting control channels allows the user to create multiple lighting layouts (and dimming sequences) based on their individual preferences.

Besides controlling your room, if a problem is detected by the HCS-3, a warning message (notification) will be sent to your smartphone. Up to 10 smoke detectors and 10 water leak-detectors can be connected to the Hydro-X Plus which will alert you if there is a fire or water leak. The HCS-3 also offers multiple advanced functions to control your entire grow room or greenhouse such as Sunrise / Sunset simulation, DLI control, overheat protection, Spectrum & Group lighting control, and more.
