  • A must have for Vivosun grow tent owners!!
I've had the GrowHub for about 3 months now and I can't imagine living without it now! I have mine controlling an AeroLight AW200 grow light, 4x LumaRay Side Lighting Bars, AeroZesh T4 inline fan, GrowCam C4 and AeroStream H19 humidifier and it has been performing seamlessly! Setup was extremely simple, just running a cable from each device to the hub - or some connect through your local wi-fi. Adding new devices has been a breeze with no issues thus far. To be fair, once the initial setup was done and I got the GrowHub connected to the mobile app on my Android phone I rarely touch the control panel itself as I'm always in the app! The mobile app is amazing! I am in the beta program and the developers have been steadily releasing updates with great new features! There are too many features to list but some of my favorites are being able to check in on my grow cam along with the current climate conditions even if I'm out. You can use youe grow cam to record a time lapse of your grow. You can set a lighting schedule, intensity, and spectrum. You can set the inline fan to work on a schedule or to activate when pre set humidty or temperature conditions are met. There is a journal section where you can log your watering, nutrition, lamp height, etc. You can also attach pictures and video to each entry. You can view historical logs of your tents environmental conditions (temp, humidty, VPD). There are just too many great features with more on the way, I'm sure! I really can't recommend this product enough. It's performance has been perfect and keeps getting better. This WILL help automate and improve your growing experience! ... show more

  • Reliable, well built and rechargeable via vivosun lights & rj45 connection
Good controller, well featured. The user interface (on the panel) is a little tricky to dial-in, but once you get the hang of it, programming is pretty simple. The magnetic back is a nice feature for affixing the unit to a metal pole or using the metal backplate for mounting to fabric, etc.

  • Excellent Environmental Controller for Grow Tents
I recently purchased the VIVOSUN GrowHub Controller E42A, and it has been an outstanding addition to my grow tent setup. Here’s why I’m giving it five stars: Comprehensive Environmental Control: This controller covers all the essential aspects of a grow tent environment, including temperature, humidity, VPD, and lighting. The ability to control and monitor these parameters through a single device has made managing my grow tent much more efficient. WiFi Connectivity: The WiFi functionality is a game-changer. I can monitor and adjust settings remotely using my smartphone, which adds a layer of convenience and peace of mind. The app interface is user-friendly and provides real-time updates on the tent's conditions. Versatile Scheduling: The timer and schedule controls are very versatile. I can set precise schedules for lighting and ventilation, ensuring my plants get the right conditions at the right times. This feature is especially useful for maintaining consistent growth cycles. Easy Installation and Setup: Setting up the GrowHub Controller was straightforward. The instructions were clear, and the device integrated seamlessly with my existing equipment. The included sensors are accurate and responsive, providing reliable data. Build Quality and Design: The build quality of the controller is solid, and the design is sleek and modern. It feels durable and looks great in my grow tent setup. Overall, the VIVOSUN GrowHub Controller E42A has significantly improved the way I manage my grow tent environment. It offers excellent functionality, ease of use, and reliable performance. I highly recommend it to anyone looking for a comprehensive environmental controller for their grow tent. ... show more

  • Vague instructions, effective once figured out
We got this to be able to control light and humidity levels in our grow tent. So far it's working fine. It did take some effort to figure out how to set everything up since Vivosun's instructions are ridiculously vague though.

  • Pure Junk - find a cheaper alternative
Absolute garbage. Straight out of the box I couldn't get the display to show readings until I disconnected/connected the probe multiple times. Then the app wouldn't show any readings on my android phone. I tried my wife's iPad and the app wouldn't allow me to add a device and complete the setup. The whole reason for this purchase is to have remote monitoring. You need to master the basics before you start adding other control features. ... show more
