Description

Environmental-Responsive Control

A true game-changer from the previous generation—iControl now offers advanced temperature and humidity strategies along with real-time VPD (Vapor Pressure Deficit) monitoring. Simply set your target growing environment, and the controller will automatically adjust connected devices like fans, humidifiers, and dehumidifiers to maintain ideal conditions throughout the entire grow cycle.

All-in-One Smart Light Control — Precise, Automated, and Natural

Take full control of your grow lights with iControl: adjust brightness manually or by schedule, automate light intensity with PPFD sensing, and simulate real sunrise and sunset transitions — creating the perfect lighting environment for every growth stage.

Smart Climate Control — Perfect Temperature and Airflow, Fully Automated

Keep your grow room in the ideal climate with iControl. Precisely regulate inline and clip fans through the app — adjust speed, set schedules or cycles, and let the system automatically respond to temperature and humidity changes. From powerful ventilation to gentle natural breezes, iControl maintains stable airflow and temperature for healthier, faster plant growth.

Smart Humidity Control — Balance Your Grow Environment with Precision

Maintain the perfect humidity automatically with iControl. Connect humidifiers or dehumidifiers to set schedules, run cycles, or enable environmental mode — the system will detect real-time humidity and adjust devices accordingly to keep your grow space in the ideal range for healthy, vigorous plant growth.

Intelligent PPFD Control — Light Precision That Adapts to Your Plants

With real-time PPFD monitoring, iControl automatically adjusts your grow light’s brightness to maintain the perfect light intensity at every stage. No more guesswork — achieve consistent, optimized PPFD levels for stronger growth, higher yields, and maximum energy efficiency.

 

Soil & CO₂ Monitoring — Stay Informed, Grow Smarter

iControl provides real-time soil moisture, temperature, and CO₂ data, helping you understand your grow environment at a glance. These insights empower you to make timely adjustments for healthier plants and more efficient growing decisions.

Scalable Smart Control — Power Up to 40 LED Lights with One Controller

Designed for large-scale and commercial growers, iControl can daisy-chain up to 40 LED grow lights, delivering synchronized, stable, and intelligent lighting management across your entire grow space. One controller, total control — reliable performance for every plant, at any scale.

    I really like this device and use it to control a Mars Hydro humidifier, an iFresh inline fan and a 200W LED grow light from a different brand. I wanted to base the automation on VDP and this controller allows me to do just that. Excellent.

    Der Controller liefert dem GrowControl-System aus Frankfurt, eine sehr gute Konkurrenz. Temp. RH, VPD, Lichtzyklus, uvm. lässt sich ohne Probleme steuern. Der Controller war definitiv sein Geld wert. Vielen Dank Mars Hydro

    Super einfache Installation und Einrichtung. Habe meinen Mars Hydro Lüfter und das Licht angeschlossen. Funktioniert tadellos zusammen. Die automatischen Profile für die verschiedenen Wachstumsphasen sparen echt Zeit und Nerven. Sehr empfehlenswert.

    Bin absolut begeistert von dem Controller. Alles läuft jetzt automatisch: Lüfter, Licht, Luftfeuchte. Die App ist übersichtlich und zuverlässig. Besonders gut finde ich die Warnungen per Push-Nachricht, wenn was nicht stimmt. Einwandfreie Technik!

    Upgraded from their old light-only controller. This is a massive improvement. It actually controls everything now. The stage-based automation is my favorite feature – I set it once and forget it. Installation was a breeze. Solid piece of kit.

    Finally got my environment fully automated! Setting up the lights, fan, and humidifier was straightforward with the included cables. The app is a game-changer – I can check on things from work and the automatic VPD adjustment actually works. Took my grow to the next level.

Q & A

Is it compatible with Mars Hydro VG80 lamp? Can I be able to use dimming function in this combination? Thx! Bozena asked on December 21, 2025

The Mars Hydro VG80 does not support dimming, so it cannot be dimmed using the iControl. However, if you would like to manage scheduled on/off control for the VG80, this can be achieved through the iHub Pro smart power hub.

will i control work with other led lights with rj12 connector and option to dimm?Im from Eu and i wonder if i can use other grow equipment with marshydro icontrol and 4ac smart plugs?thx for answer Dado asked on December 7, 2025

At the moment, dimming control is only supported with Mars Hydro devices that are equipped with an RJ12 port. If you are using other brands or devices without an RJ12 connection, the iControl and 4AC smart plugs can still be used for scheduled on/off control, but dimming will not be available.
