    • Great, effective, and worth the price
Size: 9 L
Hasn’t had any issues so far, perfect for tropical plants, set it to 90% and it will fog out a small room all day long, I don’t even hear it when it’s on, literally no noise at all. Just make sure to pipe it vertically so the water runs back into the unit so you don’t have water all over the ground from perspiration ... show more

    • Awesome humidifier!
Size: 9 L

Works great! I like how you can set it in any % and increments. Such as 55%, 56%, 58% and so on. Some only do increments of 5% but not this one! It keeps my 8x3.5 on target all the time. And has a nice sized water tank to fill and lasts much longer then my older smaller humidifier! Awesome buy to add to the Vivosun hub and all works together (Lights, inline exhaust fan, cirulater fans ect) set it and forget it! And has an option for a low water alert so you don't run it dry. Also has a clear strip in the front for a sight glass to see the amount remaining or for filling. This thing is great!!! And having the app allows way more options, and a log chart, with a sensor for accurate temps, humidity, and Vpd!! Game changer!! ... show more

    • Great product for anyone trying to dial in their garden!
Size: 5 L
This is an incredible device for keeping humidity and Vpd in check. I love that it shuts offs when humidity hits desired level and then turns back on automatically as the humidity lowers. This really helps so that I’m not having to refill with water as much, plus the reservoir tank is huge, so I only have to refill with water every few days. The app is great for setting parameters and keeping readings accurate, so I’m not having to check on my plants as much. I can check the conditions of my grow tent from anywhere now. The hose attachment is also great to go directly into tent. ... show more

    • Possible overheating issue but can be solved.
Size: 5 L
Update: since my review, I read that the device sometimes overheats and needs to be fully turned off for 10-15 minutes to let it cool off. I tried that and it seems to have worked - the device responds to settings made in the App as expected. Bumping up to 4 stars. Original: I bought two of these 6, and 7 months ago respectively. They worked great at first, I have one that's just setup to run via the App, while the other is setup to run via a recipe on the Controller box that Vivosun provide. A couple of days ago, noticed the humidity in one of my tents was too low. Turns out: the humidifier just refuses to mist anymore. It will do it for a second or two when it starts up, then it will say it's misting but nothing happens, the water reservoir stays full. Even if I set target humidity to "100%", nothing happens. I also had a Vivosun AeroWave E6 fan crap out on me (the buttons on the top no longer work) and I'm starting to think that maybe Vivosun is not such a great brand when it comes to the electronic devices. Best stick to the "analog" items like tents or fabric pots. ... show more

    • Great for reptile enclosures !
Size: 5 L
Purchased this to keep a steady humidity for my tortoise enclosure. The app is very user friendly and the water tank last about 4-5. I’m able to set it to automatically come on when the humidity drops below the set level and it’s quiet. It’s very easy to clean. No different than any other humidifier. ... show more

    • Excellent Humidifier With Smart Features and Huge Capacity
Size: 19 L
The VIVOSUN AeroStream H19 Intelligent Environmental 19L Humidifier has been a fantastic addition to my setup. The large 19L capacity means I’m not constantly refilling it, and it runs for a surprisingly long time before needing attention. That alone makes it far more convenient than smaller humidifiers I’ve owned. The built-in temperature and humidity probe works really well and keeps the environment much more stable and consistent. I especially like the intelligent controls and the easy-to-use top control panel — everything is straightforward and responsive without feeling overly complicated. Mist output is strong, consistent, and adjustable, and the unit runs quieter than expected considering its size. It’s been great for maintaining proper humidity levels without constantly monitoring things manually. Build quality also feels solid and well thought out. Overall, this humidifier delivers excellent performance, smart automation, and convenience. Definitely worth it if you need a higher-capacity humidifier for a grow tent, larger room, or controlled environment setup. ... show more

    • almost perfect.
Size: 9 L
I used this in a 6x8 greenhouse for humidity and temperature monitoring. Initially, the humidity was all over the place, temp monitoring was with 4-5 degree's compared to other sensors. Contacted Vivosun and told to reset the external probe. I did that, the humidity was slightly better, but I felt that this was working way too hard to maintain 60% humidity, lowered to 55% with better results but not ideal. After 10 days I bought the H19 and found that it was able to maintain humidity with almost precision. As for temperature monitoring, I think may have been the external sensor on the H09. They are easy to set-up, wifi monitoring with the app. Ideally it is a good product, just undersized from my project. ... show more
