I love the Vivosun Smart Grow System! I’ve been replacing everything (lights, fans, exhaust) with the new SGS products since they work so well with each other and are monitored and controlled easily with the Vivosun App, which is actually pretty awesome. I’m replacing my old AC Infinity 6” (bc it was too loud and did not have smart capabilities) with the Vivosun 8” G8 inline fan to move more air more quietly. The fan itself is great quality and is lightweight so it’s not too difficult or heavy to lift and mount to the ceiling of a tent. It is pretty quiet for the amount of air it’s able to push out. Another good thing is it’s easy to clean, being able to take the fan housing apart lets u get in there to wipe away any dust that may accumulate. This was a great upgrade from the AC Infinity.

My oh my... lets start at the beginning. The packagaing first abd foremost abd most important. Comes in a very nice bixox very well packaged. Hub controller came neatly packed in its own box with display cover, that was the. Placed very snug and safely inside the packaging. The fan itself was incased in a form fitting impact formed styrofoam to protect from shipping damage. All items came out of box like they were right off the manufacturing line. Now to the good stuff. The weight of the fan vs the output is outstanding. Were all use to if you need cfms the fan usually has the weight behind it. When i plugged this up for the first time glad i had teo hands as the hurricane force winds came rolling out of it. If you like your fan to hang or be on top have no fear as this is the lightest fan i have ever felt, zero bending on the rods that hold it airborne above the fruits. Installing the controller with supplied temperature and humidity sensor was a breeze, simple usbc connection to fan and 3.5mm jack for the sensor. The screen came alive and was off to linking the controller to the vivosun app and wifi which was a breeze. Note it only supports 2.4ghz wifi not 5g wifi networks. All in all maybe 10 minutes to setup. Will certainly be linking my light to the controller as its a all in one hub. Vivo has really got the growers struggles in mind and are there to support every step of the way as needed. Love this product and will certainly be getting the smaller fan for an intake to link in as well. Five out of five, slam dunk, grabdslam touchdown this product is what you need. Love what you grow and what you grow will love you with this setup.

So far, this is incredible. I have it in a greenhouse, attached to a 6" tube going underground into a climate battery. It is fairly quiet for how much air it is moving on Max. The app is great, allowing you to control speed and see temperature history from your phone. You can hook up grow lights to it and adjust the spectrum so can do many things. My only (minor) complaint is that even on max brightness the screen is difficult to see in a sunny greenhouse. This isn't really an issue b/c I can see and adjust any setting from my phone so don't need to use the display unit.

This bad boy is perfect for my 2 x 4 tent. At its lower levels, it's enough to circulate all the air in the tent while making almost no noise. Whereas, when it's at the higher levels, it's kinda loud, I'm not gonna lie, BUT it's doing one hell of a good job and no smell is escaping from that tent. Now, for the controller, it is nice and makes the tent look (for lack of a better word) cool. I have not messed with it manually too much, so I cannot speak of that. However, the app that connects to the controller is SO easy to use and comes with preset configurations for everything in your tent (lights, fan, duct fan, humidifier, etc..) based on what stage of growth your plants are at. The controller doesn't connect to everything, but it should connect to most name-brand lights (look for ones that daisy chain with an Ethernet cord, as this is what the Vivosun controller uses). My only gripe with this product is that the controller is very dim. It's slightly better than a Game Boy in that you have to hold it perfectly in light to see the display. Otherwise, I highly recommend this if you're looking to automate some of your gardening.

I have run this thing nearly nonstop for six months in my 3-D printing room to keep the air moving and it has been great. The remote control mounted to the cabinet makes it accessible anywhere in the room and with the magnet on the back it sticks right to the cabinet side.
