VIVOSUNHumidity Controller, 1200W Dual-Stage Outlet, Pre-Wired Digital Humidistat with Dual LED Displays for Humidifier/Dehumidifier/Fan, Ideal for Greenhouse, Grow Tent, Home-Brewing, Mushroom

As described and works as intended with one month of continual use to adjust temperature and humidity of a 7'X3' grow room. **Do not run these at 100% duty cycle at max power limit**.

Very handy for humidity control.

Buyer beware!!!! Mine shorted out on me and almost burned down my house!

I love this controller. I have a regular house hold humidifier in a grow tent and this controls the humidity like a charm! It has two outlets one for humidifier and the other for dehumidifier. I don’t know how well the dehumidifier side would work because turning on and off I feel like would reset the unit if it were digital. With an analog dial on the humidifier this unit works flawlessly with it. Love it so far about 1 month into using it.

1500 Watt mention is misleading. Instruction Manual is updated to show 1200 Watt., 10 Amp.

seams to be really acurite on humidity comes with a long censor cord and is well made

great for tent

I don't care for the fact that there's only one set value and a difference from it that affects dehumidification and humidification. And that the range is only 20 plus or minus the set value. So you can't set it to dehumidify from 90 to 80 percent RH and humidify from 30 to 50 percent Rh. The best you can do is set it to say 60 plus or minus 20, so you could get dehumidification from 80 to 60 and humidification from 40 to 60. But it will stay on until it hits 60 which is too much and too precise a value to target. Essentially it doesn't target a range, only one specific value that it tries to get to. Plus and minus ranges can be different from each other, but can't bee more than 20. All in all too limited to work for a greenhouse application.
