Humidity Controller IHC200 Inkbird Humidistat Mushroom Greenhouse Pre Wired Outlet Dual Stage Humidifier Dehumidifier(new version)

With an oversized fogger in a small room for growing mushrooms, this is incredibly quick to respond and very accurately controls humidity to mushroom fruiting levels despite the fogger being way bigger than needed. Setting hysteresis to 2% works perfectly, turning on when humidity drops 2%, and off fast enough to prevent a condensing atmosphere even when set as high as 90%. I'm using it now in a 120 square foot area with an eight puck fogger. Set at 90%, humidity rises to 98% a few minutes after the fogger shuts off and all the fog evaporates. Set at 85% it goes up to 88 or 90% a couple minutes after the fogger turns off. My fogger is probably four times too big for this space, having been bought with future expansion in mind, but the Rainbird still responds fast enough to make things work OK as long as I don't try to hold humidity at 95% in a grow room torture test. Then I get a condensing atmosphere when I do that.

The media could not be loaded. Update: this humidity controller ( paired with Zoo Med Reptile Fogger Terrarium Humidifier) is the best thing I bought ! Still works great! Most part I keep it at 50.0% but changed when it kicks on (3.0%). When Angus started sporting his zombie eyes and his whole body is dull. I turned the controller up to 55.0% for a few days, then kick it up to 60.0% and left it there. I also have on the top of his tank cover half of the top.Well he finally shed! And it’s not in several pieces. But only his body and head. But they are solid piece! Trust me when I say I Don’t know everything, I’m still learning! But to me I’m headed in the right direction!!So far I’m loving it I haven’t set the settings to what I actually want, yet! But what it looks like the default settings is 50% and if it goes 5% below or above, it will kick on and off accordingly. I’m using this Device for a ball python tank. And only have a humidifier hooked up to it. Only once the dehumidifier side did kick on, even though I don’t have a dehumidifier. I have not heard no alarm go off. Just make sure you have water in your humidifier!As of now, yes I’m going to be buying another one of these for my other snake.Anything changes, I will update.

Pros:* Works perfect- turns on humidifier when too low(which you can set), turns off when reaches the set humidityCons:* A bit time consuming to setup, manual a bit hard to follow, but you'll eventually get it setup (and once it is, you're good)* The little humidity sensor on the wire is NOT waterproof! Mine accidentally fell in some water when I was dumping it out, and it errored out for several days. I ended up having to break the plastic to get to the chip inside, let it dry out, spun it around like crazy, and now it's not beeping loudly all the time (with an error message). I'm not sure whether it's getting the right humidity level anymore, and need to find a replacement chip/ sensor (but the overall device did give the loud warning that the sensor wasn't giving the right info).

Bought this product to control an evaporative cooler so it would function as a humidifier in a large room. We are not using the dehumidifier function, but it should work for that also. Programing is easy enough with the instructions, but is NOT intuitive -- don't lose the instructions. It would be better if they printed the instructions ON the device itself with a decal. It would also be improved if they labeled the outlets. One turns on at below setpoint, the other turns off if below setpoint (dehumdifier function). It has a delay start for the dehumidifier outlet, which is a good touch. It has adjustable deadband and set point. It says it can be calibrated, but we didn't need to. The sensor is permanently attached by a modestly long cable; it would be better if it was extendable or if the cable was longer to allow better positioning of the sensor. (I think its about 6 feet long). As a pre-assembled, ready to use humidistat, it's a fair value.

Customer service is excellent. Quick to solve any problem that may arise. Stand behind their products. Would buy inkbird items again.

Easy to set up, will take reading the directions at least once(twice in my case). Other than that, it's smooth sailing, this dead on accurate. Using in my tent its holds 65% humidity with out issue, I have mine set to kick the humidifier on at >60% and vents on at <70% with a 5% deviance to hold the 65%. Took no time to set this up first try. I just bought the temp control too. Really enjoying Inkbird. New loyal customer right here.

I wanted something that could detect the humidity accurately in my basement that could turn my dehumidifier on ONLY when needed. By default, the dehum fan runs constantly to in order to accurately detect the humidity in the room, but this results in LOTS of wasted energy. I previously had it set up on a timer but didn't like the thought that I couldn't control it running when it needed to and not running when it didn't. THIS WAS THE PERFECT SOLUTION. You can set your desired humidity level and the differential as well (for example: desired humidity 55% with a differential of 10%, it would allow it to reach 65% before turning the dehum on and then take it down to 55% then shut off). There are even alarms for high and low humidity levels! I would say priced well for the value for sure! Looking forward to saving money for years to come!

I bought this a while back as a backup for a dehumidifier but never ended up using it. Recently started growing mushrooms and the read out is almost dead on. Now for the bad and unforgivable. 3 times now this units relay has gotten stuck and kept the humidification system running even though the unit show its no longer in humidifier mode. Other reviews have stated the same thing. It's running a humidifier that draw 3 amps which is well within specs. Came home to a grow tent that had standing water, water on the ceiling/walls, and a quite bit of water on thankfully a concrete floor. I took that unit out out of service today and will only use it to show humidity levels.
