Great Controller!
Size: GrowHub E42A+
This worked better than I expected at helping me maintain my peppers. It's so convenient being able to check the temperature of my peppers and manage the air circulation. I'm a big fan

Absolute Must Have
Size: GrowHub E42A+
If you are deciding on whether or not to buy this and looking through reviews, ABSOLUTELY BUY THIS! I have been newly experimenting with their products and this controller makes so much possible with automating processes. I have relied on their recommendations with lighting, airflow, watering, etc. and have had INCREDIBLE results. The screen is lit nice and all of the information is right there. The WiFi connection was good and I can control everything from my phone with their really nice app. I reached out to their customer service with a few questions and received wonderful experiences there also. Quick response and helpful information. Can’t say enough good things. Really hope to get into one of their alpha/beta opportunities one day.

A must have for Vivosun grow tent owners!!
Size: GrowHub E42A+
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!

Does not run lights separately but over all great hub
Size: GrowHub E42A+
Just upgraded my hub to the plus and so far I like it I had many issues keeping the temp and humidity correct on the old hub so far this one is staying on about right both temp and humidity are off by one degree (only been installed for 3hours) anyways the reason I bought the new hub was because I had added the Luma ray side bar lights too my 4x4 tent and I have 2 200wat aero light wing lights. I was hoping to be able to run all of it on the new hub which you can but you can’t run the side bar lights and the over head lights separately unless you use both hubs which was kinda disappointing honestly. But the fact the temp and humidity readings are staying correct and I don’t have to adjust them a 100 times and hope they stay correct is a huge win. So now I use the old hub to control the luma side bar lights only and the new hub runs the fans and the lights and exhaust.

Zeroed in!
Size: GrowHub E42A+
This allowed me to zero in my humidity and temperatures so acutely it's amazing. Controlling my lighting my fans my filters everything is so easy and be able to look at past logs looking at mistakes I've made to changes that improved my yield. All this is absolutely incredible and the fact that I can expand to many tents with one controller. Amazing! You can program multiple different tents "gardens". Multiple ways to set up the auto functionalities whether it's designing your own recipe and grow automatic growth schedules to setting the filters and fans to kick in due to humidity increase or decrease or temperature increase and decrease I mean literally everything, it's amazing 👍😎

Stay away from Vivosun
Size: GrowHub E42A+
This is the second one i have purchased. The first one would not report interior temperature or humidity. Now the second one does the same thing. Vivosun customer service is a joke, to warranty the item they asked for a video of my set up and pictures. i offered to send them the old one and they could send me a replacement, but no they still wanted video and pictures so i just purchased the replacement and it does the same thing. Research the E42A+ controller and this is a very common problem with this unit, and yes updated to the latest firmware. This was my first And last Vivosun Grow Tent, for $700 you should expect better quality but you get a inferior product.
