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!!

This puts out a lot of humidity. It’s very simple to clean and assemble. Easy to refill and has wheels so it’s easy to move around. There is no sound when running & it appears to be durable. I’m impressed with its effectiveness and with the hose accessories I’m able to reach all my plants.

Hands down a really good humidifier works really great and never gives me problems I run it 24/7 and so far it’s been a beast more then happy with this purchase and it’s a really good price also I have this little guy in my 4x8

Nice little humidifier. Does well in my 2’x2’x3’. Love that I can check in on things through the app. Notifications in app are also a nice bonus. Get alerts when anything goes out of the ranges you set. Over all I would recommend and would buy again.

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.

I was using a no name brand combo humidifier/dehumidifier combo that was advertised as being fully automatic (set the rh and forget it kinda thing) it was anything BUT user friendly... it wpuld either humidity or dehumidify but wouldnt auto switch between the 2 like it was suppose to... that unit was almost $200... waste of money... THIS THING... Holy hell is it awesome... I set the rh level and it automatically keeps it within 2% on either side... it's been a game changer for my indoor grows and seedlings !!! I can easily see current real time temps, RH% and VPD stats... absolutely recommend this product line... if you have the space to grow more go bigger... I only have a small 2x4 tent but it could be used for much bigger (I beleive its advertised for 250 sq ft dont quote me though)

I have a few other VIVOSUN products.. 10/10 on everything.. longevity and efficiency.. I have had the VS 1000 light, for a couple years.. I recently needed a humidifier.. and I got the 9 L (2.38 gallon) one.. the automation to the app is that what absolutely sold me on the Wi-Fi automation in general!! Not only was the humidity/VPD changeable from the app on my phone- I just decided to get the GrubHub and plug in everything!! (Right now that’s just a duct fan and one of my VS 1000 Viva suns) otherwise the current lights I’m running are not supported by the GrubHub.. maybe one day..,! In fact I bought a brand new 6 inch exhaust fan with the same smart Wi-Fi app capability… be cool to have the option changing my environment fWhile away from the tent .. loving this brand soooo much … slowly building up to my hole set up being Vivosun .. tent, environment, only thing next will be my main lights.. and then I will literally have every single thing controlled through the app!! For right now the lights that I have with timers are fine.. The only thing preventing me from giving this five stars is I feel they should only make the biggest model.. I believe that one holds 19 L. Still awesome… but I should’ve got the biggest one.( my dad’s a plumber so I grabbed one of his condensate pumps. And I have it run about every two or three hours pumping about a half gallon of water into the humidifier so I don’t have to constantly fill it manually) my dad has so many useful things being a plumber lol

I use this to humidify my frog tank. I wish I had the ability to set a high and low humidity. I have to set it to turn on at intervals and watch the log to make sure my tank stays within the desired parameters.Minus one star because it is really sensitive. If you bump it, it will sometimes say low water and shut off, even if the tank is full. What I have to do in that case is take the water tank off, dump the base, turn the base upside down and shake it, and then reassemble it in order for it to recognize it that it has water in it. Once I had to restore it back to factory settings to get it to work.I do love the app capability, so I can see the temperature and humidity from anywhere, and review the log to see how the mist affects the temperature in my tank.The humidifier looks very sleek, and I like the tank capacity and the low noise level. I just wish it was less temperamental when moving it about.

Ich bin echt angetan von Produkt – die Handhabung ist ausgesprochen einfach und intuitiv, sodass ich mich sofort wohl damit gefühlt habe. Die Bedienung erklärt sich fast von selbst, auch ohne langes Nachdenken oder Anleitung.Die Verarbeitung macht einen soliden Eindruck: Alles sitzt sauber, die Materialien wirken hochwertig und langlebig, und auch nach mehrmaliger Nutzung bleibt alles stabil. Dieses Gefühl von Qualität ist bei günstigeren Alternativen oft nicht so stark gegeben.Kurz gesagt: Wenn du etwas suchst, das unkompliziert funktioniert und zugleich gut verarbeitet ist, dann bist du hier richtig. Ich würde das Produkt definitiv weiterempfehlen.

Fonctionne très bien et de bonne qualité. Je recommande.
