Vivosun GrowHub Controller E42A+

Take full command of your indoor grow environment with the VIVOSUN GrowHub New Gen E42A Controller, the central brain of the VIVOSUN smart grow ecosystem. Designed for serious growers, the E42A unifies lighting, ventilation, airflow, and environmental monitoring into one intelligent control hub, giving you precise, automated control over every stage of plant growth.

Powered by advanced environmental sensing technology, the E42A continuously monitors temperature, humidity, and VPD (vapour pressure deficit) using a high-precision external probe. This real-time data allows the system to automatically adjust connected devices such as fans, lights, and ducting systems to maintain stable and optimal grow conditions.

With built-in WiFi connectivity and full VIVOSUN App integration, the GrowHub E42A enables remote monitoring and control from anywhere. Create custom grow recipes, automate climate cycles for germination, vegetative, and flowering stages, and receive instant alerts when conditions change—giving you complete visibility and control over your grow space at all times.

The E42A is designed to scale with your setup, supporting multiple devices through the VIVOSUN Smart Grow System. Whether you’re managing a compact grow tent or a fully equipped multi-device environment, it provides seamless synchronisation and intelligent automation across your entire system.

Its intuitive touchscreen interface, magnetic mounting design, and plug-and-play compatibility make installation simple, while advanced programming options give experienced growers the flexibility to fine-tune every environmental variable.
