Mars Hydro Controller 43 Smart Grow Tent Climate Controller with 3-in-1 Temperature, Humidity & PPFD Sensor

The Mars Hydro Controller 43 is a professional smart grow tent climate controller designed for growers who want maximum control over their indoor growing environment. This advanced Smart Control System monitors and optimizes crucial climate factors such as temperature, humidity, VPD, CO₂, and light intensity (PPFD) for a stable, efficient, and highly productive growing environment.

By collecting real-time data and automatically controlling compatible Mars Hydro LED grow lights, the Controller 43 creates a precisely tuned growth strategy for every stage of seedling and vegetative growth to flowering.

The result: consistent performance, stronger plant development and maximum yield per m².

Why a Climate Controller is Essential for Indoor Growing

In professional indoor growing, stability is key. Fluctuations in temperature, humidity, or light intensity can lead to growth retardation, stress, or lower yields.

With the Mars Hydro Controller 43 you can manage:

• Temperature control for optimal metabolic activity
• Humidity for controlled perspiration
• VPD optimization for maximum nutrient uptake
• CO₂ monitoring for efficient photosynthesis
• PPFD measurements for perfect light intensity

This integrated approach increases growth rate, root development and flowering performance.

Key Features

3-in-1 Climate Sensor with PPFD Measurement

The included 3-in-1 sensor measures:

• Temperature
• Relative humidity
• Light intensity (PPFD)

This gives you complete insight into your grow tent climate and allows you to precisely control VPD values ​​for optimal plant performance.

For accurate PPFD measurements:
Remove the gray cover to expose the white sensor and place it directly under the center of the LED light without any shadows.

Supports Up to 40 Mars Hydro LED Grow Lights

The Controller 43 can control up to 40 Mars Hydro LED grow lights in series . This makes the system suitable for:

• Compact home grow tents
• Medium-sized growing setups
• Professional indoor growing spaces

NB:
The Controller 43 does not control inline exhaust fans or oscillating clip fans. For 230V devices, the iHub-4AC is required separately.

Smart App control via MarsPro

Manage your entire growing environment remotely via the MarsPro app :

• Adjust settings via WiFi
• Real-time climate monitoring
• Set automatic light schedules
