Mars Hydro iControl Grow Room Controller

Mars Hydro iControl Smart Grow Room Controller

Managing multiple devices separately while trying to maintain optimal grow conditions creates constant guesswork and inconsistent results. The Mars Hydro iControl Smart Grow Room Controller eliminates this complexity by automating your entire environment through WiFi-connected control of Mars Hydro lights, fans, humidifiers, dehumidifiers, and sensors—all managed from a single app interface with real-time VPD monitoring and stage-based automation.

The iControl represents a complete evolution from previous Mars Hydro controllers. This standalone smart hub connects to Mars Hydro devices via RJ12 connections, orchestrating your full spectrum LED grow lights, ventilation fans, 6L humidifiers, and environmental sensors into one unified automation system. Set your target temperature, humidity, and VPD parameters, and the iControl automatically adjusts connected equipment to maintain ideal conditions throughout each growth phase. The system includes intelligent stage-based programming that transitions your environment settings from seedling to vegetative to flowering stages based on your customized timeline.

Unlike basic timers or single-device controllers, the iControl provides true environmental control with expandable sensor integration. Add optional PPFD sensors for precision light intensity management, soil moisture sensors for irrigation optimization, or CO₂ sensors to trigger supplementation at specific PPM thresholds. The companion app delivers remote monitoring, comprehensive data logging, and instant alerts for device disconnections, temperature spikes, or humidifier refill notifications—giving you complete visibility and control whether you're on-site or managing your grow remotely.

FAQ

Is the iControl compatible with my existing Mars Hydro Controller43 or older iHub-4AC? +

No, this is the latest iControl model with upgraded features and a completely new system design. It is not compatible with previous Controller43 controllers or older Mars Hydro iHub-4AC power strips. To use the new environmental control functions, you'll need the new iControl and compatible Mars Hydro devices with RJ12 connectivity.

For a simpler, Bluetooth-based solution, consider the Mars Hydro iConnect controller.

What devices can I connect to the iControl controller? +

The iControl connects to Mars Hydro grow lights, including efficient models like the FC-E 4800, ventilation fans, the 6L humidifier, and various sensors via RJ12 cables. You can expand the system with iHub Pro or iHub-4AC units to control additional equipment like dehumidifiers. The included T-shape splitters make it easy to connect multiple devices to a single controller.

How does the stage-based automation work? +

Stage-based automation allows you to create custom environment profiles for seedling, vegetative, and flowering phases with specific temperature, humidity, VPD, and lighting parameters for each stage. Set your desired timeline for each phase, and the iControl automatically transitions to the next stage's settings when the time comes, ensuring your plants always receive optimal conditions without manual intervention.

What sensors are included and what additional sensors can I add? +

The iControl includes a temperature/humidity 2-in-1 sensor. You can expand with optional sensors sold separately: PPFD sensors for precise light intensity automation, soil moisture sensors for irrigation optimization and nutrient tracking, and CO₂ sensors to trigger supplementation systems based on real-time PPM readings.

How does the VPD monitoring improve my grow? +

VPD (Vapor Pressure Deficit) monitoring measures the difference between the moisture in the air and the moisture plants can hold, indicating optimal transpiration rates. The iControl uses real-time VPD data to automatically adjust temperature and humidity through connected devices, maintaining the ideal range for each growth stage to maximize nutrient uptake, growth rates, and overall plant health.

Can I control the iControl when I'm away from home? +

Yes, the iControl connects to your WiFi network, allowing full remote access through the companion app from anywhere with internet connectivity. You can monitor real-time conditions, adjust settings, view historical data logs, and receive instant alerts for any issues regardless of your physical location.

What kind of alerts does the iControl send? +

The iControl app sends instant notifications for critical events including device disconnections, temperature spikes or drops beyond your set thresholds, humidity extremes, and low water levels in connected humidifiers. These alerts help you respond quickly to potential issues before they impact your plants.

Do I need any special equipment to connect multiple devices? +

The iControl package includes everything you need to get started: 4 RJ12 T-shape splitters for connecting multiple devices, 3 short (0.82ft) RJ12 cords, and 5 long (8.2ft) RJ12 cords. The T-shape splitters allow you to daisy-chain devices together, making it simple to expand your system without additional adapters or complicated wiring.
