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.
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.
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.
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.
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.
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.
