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.

I'm Not Disappointed ...
Size: 1 Kit, Size: 1 Kit
I knew going in that my expectations shouldn't be very high because my car is a first generation 2010 Kia Soul. So its old with 16 plus years of yellowing oxidation and some abrasion. I took a chance with doing this because of the reviews and pictures. To my surprise, it worked better than I anticipated and could hope for. My driver side(left) headlight was horrible but my passenger side(right) wasn't too shabby and didn't require as much care. This would have turned out better if I had power drill attachments of the same sanding grit to do this. My arm is going to be really sore come Sunday. 😆 It wasn't too hard to follow the instructions as they were very simple for the application process. I don't know about the 2 years for it lasting, but for now, its durable. Once I drive at night, I'll be able to But all in all, it worked for me and its better than before I tackled it. All in all it looks good, I feel like I'll have a better beam when night 🌙 driving.

Let this restoration kit light up your life
Size: 1 Kit
I have a car that is 24 years old and is my daily driver.  Understandably, the headlight lenses have deteriorated to the point where I was using my brights exclusively at night yet never being flashed to turn them down.  I got quotes between 60-80 dollars per headlight for restoration which I just wasn't willing to pay so I decided on this kit to try restoring them myself.  I read reviews before I ever make a decision on a product and noticed many reviewers of other products stated that this product works better so I went ahead and purchased it.  Man, am I glad I did!!!   The kit arrived late this afternoon, I opened it, READ AND FOLLOWED THE INSTRUCTIONS and within 1 1/2 hours had turned a travesty into a triumph.  I started by taping around both lights with 1 inch blue painters tape to protect the paint around the lights.  The kit comes with everything necessary to remove most moderate deterioration but be sure to purchase one that corresponds with your actual situation.  I believe my lenses were far beyond "moderate" but with some heavy elbow grease, the correct use of both supplied sanding disks and my hose set on "mist" I was able to sand off years of damage leaving behind a smooth, albeit opaque surface.  After making sure everything was totally dry using both towels and my leaf blower, I was ready for the Magic!!!  I opened the first clearcoat package (while wearing the provided glove) and lightly but steadily applied the liquid with the supplied towelette and the required 50% overlapping passes.  The opaque lenses instantly turned clear upon contact with the clearcoat.  After waiting around 25 minutes to be sure the lenses were completely dry I opened the second package of clearcoat and applied it in the same manner as the first.  I had no misses or problems with my first coat but for those who do...NOW is the time to make corrections, NOT during the first coat process.  Leave things to dry for around an hour and you are done. The end result?  AWESOME, INCREDIBLE, UNBELIEVABLE...shall I go on???  Not necessary, but I can say I am thrilled with the outcome.  My wife said the lights look new and I agree, there is a night and day difference between before and after. Only time will tell how long the restoration lasts but for now I am very very happy with the results I got from this 3M product.  I highly recommend it to anybody who can read, understand and follow the instructions.  5 stars all the way on this one!!!
