I have been looking at this for about 2 weeks now before I pulled the trigger. It says it’s the 6” version, but it’s only a 4”. VIVOSUN was kind enough to reach out and take care of the issue with a partial refund. Even at 4” in a 4x4 tent, it’s doing it’s job and was simple enough to set up. I did have to calibrate the temp and humidity with a proper gauge though, so be warned. Most people don’t think of that. There are guides on how to do it online. Cables were plenty long enough also which is a big plus in my books. More plug-in options would be a plus on the growhub, but other than that, I am very happy with this! Can’t wait to see what else VS brings out to optimize your grows inside your tents!
