VIVOSUNAeroStream H19 Intelligent Environmental 19L Humidifier with Temp & Humidity Probe, Top Control Panel, Smart Remote Control, Designed Specifically for Use with Grow Tents

April 27th 2025 I am updating my review for this product. as I had to return it .This company is awesome. I own practically everything they sell. I just happened to get a buggy unit. I would not have left the house on auto and felt comfortable. It's not the unit, the unit is fine, it was the fact I just received a unit that was malfunctioning. The unit is light weight , fills easily, connects flawlessly and quickly. (Had purchased another brand and could not connect after spending hours trying)So my review although I received a unit that didn't work right is A+ as I know others that use it. I will say the APP is so over engineered you need a very high IQ to comprehend it, use it, with the bazillion features it has.Someone needs to make a simple APP OFF, ON ,THERMOSTAT, TIMER, the app for this unit is like for a cannabis warehouse, which is cool, its just has too much going on to run a simple $60.00 humidifier. Maybe produce a LITE just for the humidifier without all the bells and whistles, and let me tell you this app has a lot of bells and Whistles.Highly recommend anything this company sells,

Very simple to use. I recommend actually reading the user manual to get the most out of this humidifier. It worked wonders in my 2x4 tent during the dry winter months when my small humidifiers (had 2 going) didn’t cut it. I set this on a low mist setting for my size tent but I feel like it would work just as well on tents twice that size or more. Customizable settings, grow hub compatible, decent size tank and easy to clean. Definitely clean it often. I rinse it out completely every time I refill it (about every 2 or 3 days) and I still got the mold smell at around 2 months. Now I wipe it out with soapy water every other fill and it’s been great. Highly recommend.

I've been an indoor farmer for 22 years, and will not lie...I have never even thought about one of the huge secrets of successful growing. Embarrassed to I've never thought about the importance of proper humidity and how it definitely will make a difference in your harvests. When I learned that VivoSun has produced this augment to growing, I did a ton of research. I am now ready for the finest harvests ever, and VivoSun, please keep upping my growing game. Your company is beloved to me.

Has out performed what I imagined, amazing set up with the app and use of it from outside the tent with the probe being smack dab in the middle love it.

Make sure to connect to the app before trying to set any controls it will save you time, app is great. Humidifier itself works as intended and filling is not hard. Can't hear it unless you are within a few feet and it's quiet. For the price it's a great tent humidity.

Calling this product line “smart” is a bold-faced lie. The humidity control? Pure fiction. It keeps running endlessly regardless of the set threshold until it drains itself dry—then expects you to refill it like some kind of unpaid intern. The wheels? Tiny plastic jokes that feel like they were borrowed from a toy car, not a device meant to hold and move a tank of water.I’ve given this system every chance to prove itself. Tweaked settings, checked placement, babied it like an overhyped Kickstarter gadget—and still, it fails at the basics. There’s nothing “smart” about a system that can't follow its own core function.Avoid this overpriced, overmarketed piece of frustration. You’ll save money and sanity.

I've been using this humidifier for a few months now and it's absolutely wonderful! I love being able to set a humidty target and let it handle the rest! It's also great being able to connect to it through the VivoSun mobile app!I'm giving it 4 stars because out of all my VivoSun devices, this is the only one that periodically loses connection to my mobile app requiring me to restart my router to get it to reconnect.Despite this trivial issue, the humidifier works perfectly. The mist levels are great and the remote operability through the mobile app and GrowHub are top notch!

Well worth the money, super easy to use and keeps humidity right where I want it.
