1. Can the iControl controller work with older Mars Hydro iHub or controller models??
No, the iControl Smart Controller is only compatible with the new generation iHub devices such as iHub Pro and iHub-4AC. The old iHub and older controller model (Controller43) cannot be used with the iControl controller due to hardware and protocol differences. Additionally, the new iHub-4AC also cannot be connected to the old controller.

2. What types of devices can be connected to the iControl controller, and how many??
The iControl controller can connect multiple devices including LED grow lights, clip fans, inline fan, humidifer, iHub Pro units, and iHub-4AC power strips. The actual number may vary depending on the total power capacity and how many RJ12 ports are available on the iControl. It’s best to refer to Mars Hydro’s user manual for specific port limits and safe load guidelines.

3. What is the difference between iHub Pro and iHub-4AC?
iHub Pro is a smart power strip that works independently, with built-in smart control capabilities. It can be used without the iControl controller and supports smart environmental strategies. In contrast, iHub-4AC requires the iControl controller to enable its smart features and cannot function independently.

4. Can iHub Pro or iHub-4AC control devices from other brands?
Mars Hydro’s smart control system is designed exclusively for Mars Hydro products. While other brand devices can be powered through the iHub Pro or iHub-4AC outlets, only basic timer functions (e.g., On/Off scheduling and environmental triggers) can be used. Advanced features like light dimming and fan speed control are not supported for third-party devices.

5. Are new and old Mars Hydro sensors compatible across controllers??
Yes, both old and new sensors are compatible with either the old controller (Controller43) or the new iControl controller.
This ensures flexible upgrades and sensor reuse across generations.

6. What are the differences between the new iHub-4AC and the old version?
The new iHub-4AC is exclusively compatible with the iControl smart controller, while the older version is only compatible with the previous Controller43.
Functionally, the new iHub-4AC offers an additional feature: environmental control strategies, allowing users to set devices to respond to temperature and humidity thresholds.
This makes the new version more advanced and integrated with Mars Hydro’s smart ecosystem..

7.How does the new iControl controller differ from the old Controller43?
The older Controller43 was limited to smart control of LED grow lights only.
In contrast, the new iControl controller supports a wide range of Mars Hydro smart products, including inline fans, clip fans, humidity control devices, and more products planned for future integration.
It also introduces comprehensive environmental strategies, making it a more powerful and flexible controller for modern grow setups.

8.What is the maximum wattage capacity of the iHub Pro power strip?

The maximum supported wattage depends on the regional version of the power strip:

US standard: up to 1875W

EU standard: up to 3680W

9.Can one iControl smart controller control multiple grow tents or rooms?

The iControl Smart Controller is recommended for use in only one grow tent at a time.
This is because each controller or smart power strip can only read data from one sensor set, making it impossible to accurately control devices across multiple tents with different environments.
Additionally, the controller can support up to 2 groups of LED grow lights, 1 group of clip fans, 1 inline fan, and 1 6L humidifier. While LEDs and clip fans can be daisy-chained for convenience, all devices connected in a chain must follow the same switching strategy and cannot be programmed with individual settings.

10.Can one iHub Pro power strip control multiple grow tents or rooms?

It is generally recommended to use one iHub Pro smart power strip per grow tent or grow room.
There are two main reasons for this limitation:

1. An iHub Pro can only recognize data from one set of sensors (temperature & humidity, soil, CO₂, and PPFD). If connected to multiple tents, it cannot accurately control devices according to the unique environmental conditions of each space.

2. Each iHub Pro can only run one grow scene strategy at a time, and it cannot execute multiple grow strategies simultaneously.

However, if a user only wants to set basic On/Off schedules for each outlet without relying on scene strategies or environmental triggers, then one iHub Pro can technically be connected to devices in multiple tents and used for simple, separate timing control.
