Intelligent Programming for 4 Types of Lamps

The Controller 43 is specifically designed for intelligent programming of LED grow lights, UV, IR, RED, and BLUE lights. By connecting the controller to a dimming box through an RJ12 cable, you can control grow lights with customized LED intensity or PPFD value(Par sensor needed), operating schedules, and growth strategies tailored to each plant development stage,the system also simulates natural sunrise and sunset for optimal plant growth.

With the addition of the iHub-4AC power strip, you can automate ON/OFF switching and timing functions for the UV, IR, RED, and BLUE light bars. This setup allows for precise control over the lighting spectrum, duration, and intensity, enhancing the growth environment to meet specific needs at every stage of plant growth.

3 Types of Comprehensive Environment Monitoring

The Controller 43 kits added Temperature/Humidity/Light 3-in-1 Sensor,Par Sensor,and CO₂ Sensor,offers comprehensive environmental monitoring capabilities, including temperature, humidity, lighting,PPFD value and CO₂ levels.

With the Temp/Humid/Light 3-in-1 sensor, you can detect the current environmental temperature/humidity data and sense the presence of light. (It cannot measure PPFD values.)

By connecting the PAR sensor, the controller can operate in PPFD mode, allowing the grow light to automatically adjust its intensity based on the set PPFD value.

This system ensures optimal and stable conditions, promotes efficient photosynthesis and healthy development, and maximizes respiration and yield.

Remote Control Convenience

With the Controller 43 and MarsPro APP, you can effortlessly manage and regulate your grow environment from anywhere. Its remote control feature allows you to make necessary adjustments and monitor plant health, even when you’re away from your grow space. Stay connected and in control at all times.

Multiple Lights in Series Compatibility

Designed to cater to different grow setups, the Mars Hydro Controller 43 seamlessly integrates with up to 40pcs lights in series. This compatibility allows for efficient and synchronized management of lighting schedules, ensuring uniform coverage and maximizing growth potential for your plants.

Safety Warning Function

 

Your plant’s safety is our top priority. The Controller 43 is equipped with a safety warning system that allows you to set alert thresholds for temperature, humidity, CO2, and PPFD levels. In the event of any abnormal conditions or potential risks in your grow space, it will immediately notify you. Stay informed and proactively address issues to ensure the health and well-being of your plants.

Widely Applicable

 

The Mars Hydro Controller 43 is highly versatile, making it suitable for a broad range of indoor growing setups, from small home grows to large-scale commercial operations. Its advanced features can accommodate various plant types, including vegetables, herbs, and flowers, ensuring optimal conditions in diverse environments like grow rooms, greenhouses, and research labs.

    Nice controller

    pepask (Grower) – April 25, 2025

    Rated 3 out of 5

    Kaufgrund:
    Mein Anreiz den Controller zu kaufen war in erster Linie ein verlässlicher VPD Wert. Wenn die Umgebung schlecht ist, wächst auch Deine Pflanze schlecht, daher immer Augen auf bei den Umgebungswerten.

    Versand:
    Die Ware kommt gut und stabil verpackt im neutralen Karton per DHL bei mir an. Es wurden keine Transportschäden festgestellt. Alle Teile sind sicher und stabil verpackt.

    Aufbau:
    Hat man die Sensoren mit ihrer Gegenstelle an der Unterseite des Controllers verbunden, zeigt dieser zur Bestätigung die aktuell gemessenen Werte an. Es kann mitunter 10 Sek. dauern bis neue Werte geladen werden (Verbesserungspotenzial!). Die Positionierung ist dann von den jeweiligen Prioritäten abhängig.
    Einstellung:
    Nach dem ersten Einschalten und der WLAN-Einrichtung aktualisiert sich das Gerät selbständig. Blättert man durch die Menüs gelang man schnell zur Seite mit den Alarmeinstellungen, wo man Ober- und Untergrenzwerte manuell einstellen kann. Fällt ein Wert in so einen Grenzbereich ertönt ein Warnton und es wird eine Meldung im Controller aufgezeichnet, die über die Tasten Links und Rechts durchgeblättert werden kann.

    Aktuelles Setup:
    Bis zum Kauf habe ich mir mit zwei Smart Home Hygrometern beholfen, die jeweils +5°C und +3% RLF abwichen, aber wer schnell den Mittelwert zu errechnen gelernt hat, der kann sich die aktuellen Werte schnell ausrechnen.

    Der PPFD Sensor:
    Ein schicker kleiner Kasten mit einem Deckel, den man zur Seite drehen kann. So entblößt blickt man auf eine weiße Filterscheibe, die den PPFD Sensor abdeckt. Im Lieferumfang ist ein Teleskoparm mit Schraubgewinde für die Stangenbefestigung enthalten, worauf der Sensor gescheckt und dann festgeschraubt wird. Das Kabel des Sensors wird mit der entsprechenden Buchse auf der Unterseite des Controllers verbunden.

    Licht, Temperatur, CO2 und Feuchtigkeits-Sensor:
    Der Lichtsensor übermittelt dem Controller ob es Dunkel (Mondsymbol) oder Hell (Sonnensymbol) in der Growbox ist. Temperatur und Feuchtigkeit werden ebenfalls präzise ermittelt. Der CO2 Sensor misst die CO2 Sättigung in PPM.

    Alle Sensorwerte können kalibriert und mit Warnungen versehen werden, wie z.B. bei zu hoher Temperatur, zu hoher relativer Luftfeuchtigkeit, zu hohem PPFD und zu hoher CO2 Belastung.

    Steckdosen-Funktion:
    Ich nutze diese Funktion nicht, daher kann ich dazu nichts sagen.

    Positiv:
    – Die App stellt die Zeitzone selbst korrekt ein, die Einstellung funktioniert einwandfrei
    – Die Sensoren können nachträglich kalibriert werden
    – Das Controller-Display kann automatisch nach X Minuten abgeschaltet werden
    – Die App läuft stabil

    Negativ:
    – Obwohl die Werte kontinuierlich ermittelt und fortlaufend angezeigt werden, findet keine Aufzeichnung oder grafische Darstellung der Werte statt, was für viele sehr wichtig ist.
    – In der App gibt es kein Dashboard auf der alle aktiven Geräte gruppiert sind. Wer ein Lampe und einen Controller hat der muss zwischen vier Tabs hin und her blättern.
    – Die Tabs müssen richtig beschriftet werden, korrekte Deutsche Beschriftungen wurden bereits an den Customer Support geschickt.
    – Die Konnektivität der App über WLAN muss optimiert werden. Manchmal verliert die App die Verbindung für Minuten.

    Alle diese Vorschläge wurden bereits mit dem Customer Support besprochen. Sie werden geprüft und nach entsprechender Beratung umgesetzt.

    Kaufempfehlung?
    Ganz klar, JA! Das Gerät läuft aktuell bei mir im Zelt und tut das was es soll, Werte anzeigen. Was Funktionen angeht ist immer der Wunsch das Ziel, aber was das Gerät bislang liefert, ist ok. Warum nur drei Sterne fragt Ihr Euch?

    Ganz einfach. Ich finde dass MH mit diesem Controller noch nicht das volle Potenzial seiner Hardware gezeigt hat. Ich denke dass das Gerät nach entsprechenden Updates auch mit professionellen Sensoren mithalten kann.

    Before using this, I had to manually adjust everything. Now, my grow room stays stable without constant monitoring. The sensors are highly accurate, and the device is very responsive.

    I love the automation and precise control this smart controller offers. The only downside is the learning curve—it took me some time to understand all the settings. Once set up, it works like a charm!

    The functionality of the controller is very handy. You can control temp, humidity, co2, vpd, and ppfd, if you buy all the available sensors. Furthermore there is a power string, iHub-4C, that can be connected to the controller, so youcan configure the on/off time of the sockets on it. I can’t say anything about the other sensors, because I don’ t own them, but the read out values of the temp and humidity are very accurate. So, untill now I am satisfied with the product.

    The controller is great. A great thing in conjunction with the MarsPro app. The controller is very easy to set up in the app.
    The option of firmware updates via Wi-Fi means that bugs can be fixed quickly and easily. That’s great.
    After the last firmware update, the sunrise and sunset now work perfectly. Super! I am very satisfied.
    The PPFD sensor is also great and very accurate. I have clamped it on a mobile phone tripod and so I can adjust it exactly to plant height.
    I hope that the iHub-4AC will soon be available in the EU shop so that I can control my 3 MarsHydro additional lights (UV, IR, Deep Red).
    Thank you Mars Hydro for the good products. I hope there are many more great things to come from you.

Zur Zeit ausverkauft ? Wird es Nachschub geben ? Markus Beuck asked on July 16, 2025

Hallo Markus,

Wir haben den Icontrol -Controller von 2025 und IHUB Pro. Wenn Sie mehr Mars Hydro -Produkte haben, z. B. Light, Clip -Lüfter, Inline -Lüfter, Adlite -Licht, ist IHUB Pro für Sie mehr Suitbale, was zumindest 10 Geräte steuern kann.

Buenas tardes mi pregunta es con el controlador de humedad y temperatura con eso puedes saber la umedad y la temperatura pero como la regular mi pregunta es si ese controlador k venden tiene las tomas para conectar algo k de calor cuando le aga falta y no se algo k le kite la humedad Cristian Priet asked on April 18, 2025

The controller can only monitor temperature and humidity. You can set the temperature and humidity warning value. When the warning value is reached, the controller will remind you that you can adjust heat and moisture at this time.
