Wide adjustability and simple to use
Read manual first. Simple to setup. One nice feature, on the sensor, open the case and you are able to unplug and put wire thru a small hole with a grommet if you using with a sealed cabinet like I am. Excellent adjustability range.

Great, but sensor wire is a little on the shorter side
Works great, but the sensor wire is a little short. If you use a Martha-style tent measuring humidity higher up in the tent is difficult with the length.

works great,, really clear instructions
I wanted a way to control the humidity in my new grow tent. I had a humidifier, and this controller made that fairly simple. If you follow the instructions it is easy to set up.. You plug the control into an outlet, Then you set an upper lower limit, called the run humidity, and the upper limit called the stop humidity..To make it all work you need a humidifier. Just plug the humidifier into the control and turn it on. If the ambient humidity is below the run level, the power comes on.. There is a small indicator light on the upper right of the control. Once the desired humidity is reached, it turns the power off to the humidifier. There is a warning not to set the limits close together. There is also a warning not to place the sensor (that gray piece in the last pic) too close to the humidifier. Follow the instructions, it was clearly explained.I set this all up in a grow tent, a bit larger than a phone booth, it worked just fine. One thing that I noticed was that the vapor from the humidifier sinks. To really disperse it, you need a kind of fan, some sort of ventilation. Other than that, easy peasy. I was very happy that I was able to set, then run this humidity control.
