MEISAIL 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

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!

I’ve used this for a week and so far so good. Easy to set up and install which is great considering I’ve had ones in the past that weren’t that easy. It has a large display so it’s easy to see where all your levels are at. I believe it’s accurate as I used a different brand in the same environment and they’re both readying the same. So far so happy with this product and it doesn’t break the bank.

It's a pretty good quality product. I got it set up in my greenhouse and I've had no issue setting it up or with it being out there so far. We'll see how well it works come winter.

Randomly reads 0% humidity, which keeps the humidifier on constantly. If you don't catch it in time, it can damage plants/mushrooms. Came home to a puddle after the humidifier ran all day while I was at work. Only had this for a couple days and the sensor has been in the same spot untouched.If it worked as intended, it would be great. But it seems like it wasted $30 on an unreliable product.

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.

Save your money over buying the more expensive ones as I have found that this one works perfectly and is easy to calibrate. The price as well as the other reviews had me leaning towards this one and I’m glad I got it.

This has been a noticeable difference in maintaining a consistent environment, it is easy to set up, user friendly, clear bright display and has been accurate.
