One Controller To Rule Them All.

Meet the Mars Hydro iControl Smart Grow Room Controller - the upgrade growers didn’t know they needed until they held one.

Unlike earlier controllers that only managed lights, this new version ties into your entire ecosystem: lights, fans, humidifiers, dehumidifiers and more. It doesn’t just switch things on and off - it orchestrates the dance of your grow room. Because controlling one thing is fine, but controlling everything is smart.

Smart Climate Management.

Unlike most grow room controllers, the iControl doesn’t wait for trouble - it anticipates it. Using real-time VPD (Vapour Pressure Deficit), combined with temperature and humidity sensors, it adjusts your gear on the fly.

Too humid? It’ll ramp up dehumidification. Too dry? Humidifier gets called in. Fans, extraction, intake - it’s handled. You set the ideal conditions, and the controller ensures your grow space stays there. It’s climate control with reflexes.

Grow Stage Automation.

Why fuss over seedling vs. vegetative vs. flowering stages when your controller can do it for you? 

The iControl allows custom scenarios by growth stage. Set your timelines, tell it what the room should behave like in each phase, and it swaps modes automatically.

No more forgetting to adjust humidity or light cycles when switching phases - it just does the work, leaving you free to focus on bigger-picture things like the pub, (or even your day job).

Remote App Control, Logging & Alerts.

No matter where you are, the iControl app lets you peek into your grow room. Temperature, humidity, VPD, alerts - everything’s in your pocket. It keeps detailed logs over days, weeks, and months, so you can look back and spot trends.

And if things go wrong - a disconnected sensor, a spike in temperature - you get alerts instantly. Your growroom becomes your personal Netflix show, operable from anywhere.

Ready, Set, Grow.

This is the new generation of controller. It ships with the iControl unit, a 3-in-1 temp/humidity/light sensor, RJ-12 splitters, sensor cords, hanging kits and power supply.

Set it up, link your equipment, and go. However - and this is crucial. However -it’s not backwards-compatible with older Mars Hydro lights. This is a clean slate. To enjoy full environmental control, you need the new controller and compatible devices. Treat it like a fresh start.

 

A Giant Leap Forward.

The Mars Hydro iControl Smart Grow Room Controller is more than an accessory - it’s the central brain of your grow. It handles multi-device climate automation, supports stage logic, accepts advanced sensors, logs data, and gives you remote access.

For growers who want confidence, consistency, and control (without daily tweaking), this is the tool you didn’t know you were missing - until now.
