Style: E42A Controller
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!

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.

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.

I picked up the VIVOSUN GrowHub E25 to control my AeroLights for starting vegetable seedlings indoors, and overall, it’s been a great addition to my setup. While it’s clearly designed with a different audience in mind, it still offers solid functionality for anyone looking to automate their grow tent environment. Setup & Ease of Use Right out of the box, setup was painless. The E25 connected to my Android phone immediately, and getting it onto my WiFi network was just as simple. The VIVOSUN app was straightforward, and I didn’t run into any connection issues or troubleshooting headaches—something I really appreciate in a smart device. Functionality & Performance I’m using it to control four AeroLights that are linked together, and while this is my first time using artificial light for seedlings, I’m feeling optimistic. Last year, I learned the hard way that my windows don’t provide enough natural light, so I’m hoping this setup gives me stronger, healthier plants. The app itself is very responsive, and while I’ve only browsed the automation scheduling, it looks easy enough to set up. I like the idea of having light schedules tailored to different plant growth stages, but this leads to one of my biggest gripes… Missed Opportunity for Vegetable Growers VIVOSUN’s app is clearly designed with cannabis growers in mind, which is fine—but for those of us growing vegetables, it feels like an afterthought. The default pictures of marijuana plants in the app feel out of place when I’m just trying to start tomatoes and peppers. It would be fantastic if VIVOSUN included grow recipes for common garden vegetables instead of just cannabis. Even better, if they allowed customizable grow schedules with user-uploaded images, that would make it much more versatile. Build Quality & Reliability So far, no glitches or disconnects—the connection has been rock-solid. One concern I do have is the physical design of the dongle—it sticks out a bit, and I worry about accidentally snagging it and damaging the port on the AeroLight. A right-angle or recessed connection would have been a better design choice. Pros & Cons ✅ What I Like: ✔ Super easy setup – No headaches getting it connected ✔ App is very responsive – No lag when controlling lights ✔ Controls multiple AeroLights at once – Great for my grow setup ✔ Works well for all experience levels – Beginner-friendly but powerful ✔ Reliable connection – No disconnections or weird glitches so far ❌ What Could Be Better: ✖ App is too cannabis-focused – Needs grow recipes & images for veggies ✖ Dongle design – Could be more secure to prevent accidental damage ✖ No Home Assistant integration – Would love to control it alongside other smart devices Final Thoughts – A Solid Controller with Room to Grow The VIVOSUN GrowHub E25 is a great tool for automating grow lights, and it works seamlessly for my vegetable seedlings. The easy setup, reliable app, and good automation features make it a strong choice for growers of all levels. That said, VIVOSUN could really improve this product by making it more inclusive for vegetable growers and adding Home Assistant integration. If you’re looking for a simple way to control and automate your grow lights, this is a solid pick—just be prepared to ignore all the cannabis imagery if you're growing veggies! ⭐ 4 out of 5 stars – Would be 5 stars if it had more customization for non-cannabis growers.
