Who This Is For

  • You are automating your climate because manual adjustments throughout the day interfere with your work schedule.

What We Found

  • The magnetic backing is strong enough to snap onto tent poles, which keeps the controller at eye level and accessible.
  • The app interface is surprisingly clean, making it easier to set VPD targets than clicking through buttons on a wall.

What Users Say

  • Users who deal with frequent power dips say the memory feature saves them from recalibrating the whole system.
  • Growers who travel say the phone alerts let them fix climate spikes before they cause permanent crop damage.

FAQs

What devices can I control with the GrowHub E42A+? +

The GrowHub E42A+ allows you to control your grow lights, inline fans, circulation fans, humidifiers, dehumidifiers, and other compatible grow tent accessories. All devices connect through the controller or Vivosun App, creating a unified automated system for your entire grow space. For best results, pair the E42A+ with Vivosun's complete line of smart growing equipment for seamless integration and maximum automation.

What is VPD and why does it matter? +

VPD (Vapor Pressure Deficit) measures the difference between the moisture in the air and the moisture plants can hold at saturation. The E42A+ calculates and displays VPD in real time based on temperature and humidity readings, helping you maintain optimal conditions for each growth stage without complex manual calculations.

Do I need WiFi to use the controller? +

While WiFi is required for remote access and advanced app features like grow recipes and guided pilots, the GrowHub E42A+ can still function as a standalone controller using its built-in color display and manual controls. WiFi connectivity simply unlocks the full range of smart features and remote monitoring capabilities.

How difficult is the installation process? +

Installation is designed to be quick and simple. The controller includes magnetic mounts for metal surfaces or expansion screws for other mounting options. Most users complete installation in just a few minutes. The intuitive interface guides you through device pairing and initial setup step by step.

Can the E42A+ adjust settings automatically as my plants grow? +

Yes, the E42A+ allows you to create customized automated cycles for germination, vegetative, and bloom stages. You can program specific light spectrums, intensity levels, on/off timing, temperature ranges, and airflow settings for each stage. The controller will automatically adjust your environment as your plants progress through their life cycle.

What are grow recipes and guided grow pilots? +

Grow recipes are pre-programmed environmental settings optimized for specific plant types and growth stages. Guided grow pilots provide step-by-step instructions throughout the entire grow cycle, making it easier for beginners to achieve successful harvests. Both features are accessible through the Vivosun App and take the guesswork out of creating ideal growing conditions.

Is the sensor accuracy reliable for professional growing? +

The GrowHub E42A+ features high-precision sensors that continuously track temperature, humidity, and VPD in real time with professional-grade accuracy. The sensors provide the reliable data needed for both hobbyist and commercial growing operations, enabling precise environmental control and consistent results.

Can I make adjustments while I'm away from home? +

Absolutely. Once connected to WiFi, the Vivosun App gives you full remote control over your grow space from anywhere with an internet connection. You can monitor real-time conditions, adjust settings, receive alerts, and make immediate changes to protect your plants even when you're not physically present.
