  • Real-Time Environment Data Monitor: 4 inch inline fan comes with a probe sensor so key climate data- temperature and relative humidity- can be displayed in real-time on the APP screen, whether you are near your grow unit or not. When the inline ventilation fan is operating, growers can get a clear picture of the duct fan speed (RPM) and airflow (CFM) on the screen.

By establishing a designated "safe range" for temperature and humidity, the inline fan will activate at maximum speed when the temperature or humidity is not within that range. Grow room consistently maintains an ideal climate.

Works Great. . . This fan is super powerful. Much more power than the other 2 different brand name fans that I had prior to this one, this one has plenty of Bang for the “Buck”.

The app for this fan and reaction from fan by the app is confusing and does not work as they say it should. It's either run like a fan all the time or use limit switch. However the fan will not work with limit switches at all. It just runs all the time. The app is super confusing with strategy switch limits as they don't work. Been trying to have it work with mars for 2 months, still does not work. Same with smart lights.. they don't bind to wifi when more than 1 smart light and do not work as a Daisy Chain. Mars has allot of work yet to be leader in smart tech.

If you have an Android and planned on using the app, don't bother buying the iFresh fan. No setup info as it's on the app. Scanned the QR code which opens the Play Store and shows the app can't be found. Checked the download link on their website and was met with the same result. Googled and found tons of people having issues with the app and lack of responses from Mars Hydro. Quite frustrating to buy something with app control to find it doesn't exist. Confirmed the item on here still claims to have app control but that's clearly false. Single star as it was at least packaged well.

Excellent fan for you grow tent! Whether you are home watching tv or working at the office, the iFresh lets you dial in your grow environment on your phone anytime and anywhere. The Mars Hydro app is easy to use and can control your lights and the iFresh fan.

Bought this item and then found out you cannot have 5G Internet, and use the app. Totally useless purchase.

I wanted to like this product because I've bought their tent and lights, and they were great. First, the straps are just tedious, slow and tedious. I would have been better off just using zip ties, because the straps are way to long for a tent this size, and they're cheap feeling. Second, the carbon filter and inline fan are a very loose fit. It needs to be snug to prevent the smell from escaping, and I had to use duct tape to seel it. If there was some sort of coupler that conjoins them, that was missing as well. Third, the smart controller is now integrated into the fan, so it can be accessed via the app, but there was no mention that it had been changed, and the installation video still shows the old system. Confusing. Fourth, there were no instructions of any kind, and I had to use YouTube to get an idea of what I was supposed to do. Most of the instructions were for use of the old version of smart controller. The fan and filter do look to be of decent quality, and the fan is quiet.

UPDATE: Great fan from a great company with some of the better customer support I've dealt with. Purchased in December and left the initial review. I was contacted by Mars Hydro in regards to my problem. I told them I was fine with what I received and left it at that. Jump forward almost 5 months later to the other night when I responded to their message.After a few back and forth messages, trying everything they suggested, we finally found the solution. If you're phone can't find the device in BT, make sure your location on your phone/tablet is turned ON. I'm not sure if this is stated in the operation manual or anything.They were still willing to help me fix the problem even after I told them I was okay with it not being the right one and not responding to their messages for months. This may be the first instance where customer support actually helped me to fix a problem.ORIGINAL: I ordered the iFresh inline fan, that's supposed to connect to an app on your phone. I either just can't get mine to even be discoverable on the app or I wasn't given the correct fan and just got a normal one with a speed controller and a useless temperature probe. I followed the instructions on the Mars Hydro site on how to connect it and how to reset it. Clicking the speed controller on and off 3-5 times in quick succession will cause the fan to make a clicking noise 3 times letting you know it was reset. Mine doesn't do that which make me think it's just the regular speed controlled fan.

I love the sleek stylish design. The powerful motor is a lot quieter than other big brand name inline fans. Perfect for my 3x3 grow tent, this circulates the air exceptionally well.
