There are different models of InkBird such as the ITC-608T ​ which has one input for temperature and one input for humidity. The controller comes with two input plugs, labeled “Work 1” and “Work 2.” Work 1 is where you’d plug in the humidifier and Work 2 is where you’d plug in the dehumidifer/AC/exhaust fan. Why these plugs aren’t labeled “humidifier” and “dehumidifier” is beyond me.

After setting the high and low alarm levels hit the set button again to display the delay protection time. By default this is one minute, and it can go up to 10 minutes. You may want to adjust this if your devices are turning on and off too frequently. For example content on and off cycling isn’t good for air conditioners. For most users the one minute setting will be sufficient.I have noticed a quiet buzzing sound coming from the unit, because of this, I do not have the curing chamber running close to where I’m blogging or doing other work.

When you’re looking for something which is a plug-and-play option, this really is the product for it on the market.

We’ve used the Inkbird IHC-200 controller for a few scenarios when growing weed and have found it to be very helpful. In dry conditions we have used it to turn on humidifiers in a grow tent that had a constant exhaust fan running, so the incoming air was constantly drier than ideal. The Inkbird is also helpful for situations in medium and larger grow tents where a dehumidifier is placed right inside the grow space and is set to run only when humidity exceeds 65%. As you can imagine, I prefer to not put holes into a fridge when I don’t have to. Overall Review of InkBird Controllers Once the base level is where you want it, hit the button again to bring up the low setting variance. For example if you’re looking to keep your grow room range between 40 and 60, set the humidity for 50 and then set the low differential to 10 (holding the set button down while you adjust). Then hit the set button again to show the high humidity differential, and while still holding it down set the high range to 10 as well.

The Inkbird has a 5 foot power cable to plug into a wall outlet, working with either 120v or 240v humidifiers or devices. Both plugs are rated for 12 amps.

Summary of the Inkbird IHC-200 controller

When I started doing meat curing about 15 years ago, I had an engineering friend of my brother’s who knew how to hardwire the system. Primarily you use the IHC–200 InkBird humidity controller for 70 to 75% humidity inside the curing chamber. The Inkbird IHC-200 comes set up to maintain 45%–55% humidity out-of-the-box. The default setting is 50% with a low differential of 5%, and the high differential of 5%. This means that it will automatically maintain a range of 45%–55% by turning on a humidifier below 45% and turning on a dehumidifier in conditions above 55%. This is the ideal humidity range for most grow room conditions. For the thousands of people that are interested in DIY curing chambers through this blog, I have done a lot of extensive research and have been keen to show the various options.
