Total Control of Your Grow Environment with the VIVOSUN GrowHub E42A 

The VIVOSUN GrowHub E42A Controller brings every part of your growroom under one easy-to-use platform.

It monitors and automates lights, fans, temperature, and humidity; giving you consistency, efficiency, and bigger yields without constant manual adjustment.

• All-in-one controller; run your lights, fans, and humidifiers from one hub
• Smart scheduling; dynamic timers with ramping, day/night cycles, and climate triggers
• Environment monitoring; live readouts of temperature, humidity, and VPD
• App connectivity; make changes remotely from your phone
• Expandable system; link with other Vivosun Smart Grow devices for full automation

Instead of juggling timers and switches, the GrowHub E42A gives you precision scheduling and real-time data so your plants always have the perfect conditions.

All-in-One Environmental Control

Lights, fans, humidifiers — the E42A ties them all together. Create tailored programs that adjust with the stage of growth, or let the unit automate fan speeds based on real-time climate readings. Everything is controlled through one clean, intuitive interface.

Dynamic Scheduling

Build custom on/off cycles for every device. Ramp light intensity gradually; trigger fans to kick in when temperatures rise; reduce humidity overnight. It all runs automatically once you’ve set your parameters.

App Connectivity

Pair the E42A with your smartphone to monitor and adjust your environment from anywhere. You’ll see live temp and humidity data, receive alerts, and tweak settings on the fly.

Expandable & Future-Proof

The GrowHub system is modular; as you add more Vivosun Smart Grow products (lighting, fans, sensors), they all connect back to the E42A. It’s a controller that grows with you, not one you’ll outgrow.
