The VIVOSUN GrowHub E42A is an all in one smart controller designed to give complete control over your grow environment from a single, easy to use hub. It monitors and automates lighting, airflow, temperature, and humidity to deliver consistent conditions, improved efficiency, and stronger plant performance without constant manual adjustments. Instead of juggling multiple timers and controllers, the GrowHub E42A unifies your equipment into one intelligent system. Lights, fans, and humidifiers can be controlled together or independently, allowing you to stabilise your environment and adapt it precisely to each stage of growth. Built in temperature, humidity, and VPD monitoring provides live environmental data in real time. The controller can automatically adjust connected devices in response to changing conditions, ensuring your plants stay within their ideal climate range. Dynamic scheduling allows you to create advanced programs with ramping light intensity, day and night cycles, and climate based triggers. Fans can increase speed as temperatures rise, humidity can be reduced overnight, and lighting cycles can be smoothly adjusted without sudden changes. The GrowHub E42A connects directly to your smartphone via WiFi, giving you full control wherever you are. Through the app, you can monitor live data, adjust settings, receive alerts, and access advanced features such as Grow Recipes. For pairing, a 2.4GHz WiFi network is required. Designed to grow with you, the system is fully expandable. As you add more VIVOSUN Smart Grow devices, they integrate seamlessly into the GrowHub platform, making this a future proof solution for both beginners and experienced growers.
