Humidity Controller Greenhouse Shiitake Mushrooms Humidifying dehumidifier humhumidistat controlleridity Humidity Switch Controller for Grow Ten thygrometer humidistat Controller

This Meisail humidistat has worked very well for me in my shiitake mushroom greenhouse. It accurately detects ambient humidity and turns on the misting system exactly when I need it. It's easy to set up: just adjust the minimum and maximum humidity levels, and the unit does the rest. The display is clear and the buttons are responsive. It also has a delay function to prevent the system from turning on and off constantly, which helps extend the life of the connected equipment. Excellent option if you need to maintain controlled humidity automatically and without too much hassle. I RECOMMEND IT

This humidity controller works exactly as described. I use it in a walk-in grow tent with multiple high-maintenance plants, and it’s made a big difference. Super easy to set up—just plug it in, set your desired humidity range, and it takes care of the rest. It reacts quickly and keeps the environment stable. The display is clear, and the controls are straightforward. Great choice if you need consistent humidity control in a larger setup.

This controller is built sturdy and is very accurate. The humidity reading matches multiple other hygrometer in my tent. The probe wire is also decent length.

Unit arrived today, very nicely packaged. Unit appears very well built. Directions were a bit hard to figure out, but in a matter of maybe 10 minutes I had it up and running. Using only for a humidifier that the humidistat stopped working on. This was much cheaper than a ne room humidifier. So may plusses over the built in humidistat. Remote sensing so I can get it away from the unit, Can put whatever delta you want and also has the capability to adjust the "current reading" Only using it for a humidifier right now, but in the summer I will use it on our dehumidifier, which also has a dead humidistat.

Overall, I find this product to be fairly easy to use. The user interface is simple and intuitive, which makes setup and operation straightforward. However, I’ve repeatedly encountered issues with the sensor. Despite setting the humidity threshold at 90%, the sensor often fails to work properly. After just a few hours, it will read zero humidity—even though there is no visible moisture on or around the sensor that would justify a false reading. To reset it, I constantly have to remove the sensor and let it sit in ambient air, which defeats the purpose of having an automated system. In short, while the product design is promising, the unreliable sensor makes it more hands-on than it should be.

The accuracy and Temperature control is amazing, this product is very reliable and works very well! I would highly recommend to others.

I bought this to keep a stubborn little indoor grow tent happy, and wow!!!this thing understood the assignment. It keeps the humidity exactly where I set it, no drama, no weird spikes, no mysterious overnight drops. Setup was surprisingly painless (even for someone who usually treats instruction manuals like abstract art), and I love being able to just set it and forget it!! Now instead of obsessively checking hygrometers like I'm defusing a bomb, I get to relax knowing this controller has it handled. My plants are thriving, and I might be too. 10/10 for saving me from becoming a full-time moisture detective!

Using this with my Vicks warm mist humidifier. So far it is working well. This is saving me from having to refill the humidifier multiple times at night and throughout the day. It’s also saving me on electricity, not running my old school humidifier 24/7. Taking a star off for a couple things. 1) directions are confusing. Need a little intuition and common sense/deductive skills to figure out. But once you do, it’s easy to use and control temperature/humidity. 2) the digital display is really bright and blue. No one wants a blue light glowing while trying to sleep. I sleep with an eye mask but for humans and pets that don’t, it may be nuisance. 3) would be nice to have an off button. But can easily unplug. Doesn’t make any noise which is a plus. A little pricey compared to others out there but so far quality seems to be good. Came packaged well.
