Product detailed description

VIVOSUN GrowHub Controller E42A+, Smart Environmental WiFi (Temperature, Humidity, Scheduling) for Ventilation

VIVOSUN GrowHub Controller E42A+ is an intelligent WiFi control unit designed for monitoring and automating climate conditions in grow tents. It enables speed control of compatible duct and circulation fans, monitoring of temperature and relative humidity, and automated operation of equipment according to current conditions or set schedules.

The control unit is equipped with a 4.3" colour display with six touch buttons and an external temperature and relative humidity sensor with a 3 m cable. Thanks to the combination of internal and external sensors, it can monitor climate conditions both inside and outside the growing area. The displayed values also include VPD (Vapour Pressure Deficit), an important parameter when optimising the growing environment.

Automatic ventilation control enables the speed of compatible fans to be adjusted according to temperature, relative humidity and set operating conditions. Manual modes, automatic control, timers and cyclic switching are available. Supported circulation fans can also use modes simulating natural airflow.

Thanks to WiFi connectivity and the VIVOSUN mobile app, measured values can be monitored remotely, the settings of connected devices can be adjusted and automated operating schedules can be created. GrowHub E42A+ also supports preset growing programmes, enabling the operation of individual components to be adapted to different stages of plant development.

In addition to ventilation, the unit can also control compatible LED grow lights. Supported models allow light intensity control and light-cycle setting, as well as additional functions depending on the specific light, such as adjusting the light spectrum.

For connecting accessories, the unit is equipped with five universal USB-C ports and a separate USB-C port for lighting. It supports connecting selected VIVOSUN AeroZesh and AeroWave fans. Compatible LED lights can also be connected using a USB-C to RJ11/RJ45 converter. The available control options always depend on the specific model of the connected device.

GrowHub E42A+ features magnetic mounting, allowing easy installation on the wall of a grow tent without drilling. Alternatively, fixed wall mounting can be used. Thanks to the external sensor, the control unit can be placed outside the growing area while still monitoring climate conditions inside the tent.
