Smart Air Filtration PRO T4 Kit 4", AeroZesh T4 Inline Duct Fan w/GrowHub E42A+ Temp. Humidity WiFi-Controller, Carbon Filter & Ducting Ventilation System for Grow Tent, Hydroponics

Works beautifully, can't beat the Vivosun brand,gives you everything you need and more ,plug & play .

With the controller, this thing is super awesome and quiet. Without the controller, the fan just runs at full speed and is extremely loud. Comes with everything you need, would be nice to have 2 extra pulleys.

Works as intended on a awesome level no smells, low noise, easy install and the ability to operate

I emailed Vivosun when I found that the controller wasn't working properly. At first, it seemed it was a defective probe, as it wasn't detecting the temperature or humidity. I sent videos and pictures of this issue and my setup. Vivosun sent me a new probe replacement. Once I tried the new probe and found that this didn't work either, I sent them another email with updated images of the issue. The controller was defective as it was clear at this point that the port to plug the probe in was the problem. Vivosun was quick to make it right. They sent me a controller replacement. The replacement worked PERFECTLY. I couldn't be happier with Vivosun products, and I am incredibly impressed with the quick response of their customer service! I HIGHLY recommend Vivosun products!

You will need more equipment for a grow tent. Another exhaust fan. Using it as a intake fan. You'll need a humidifier. According too which grow light u buy from them. You'll need too buy another or one that's at least 200 watts. 4×2×5 is what I bought plus everything else for a grow tent. Do the research on what all you need. Good product dont get me wrong.

Very happy w this Vivosun Smart Grow System Controller and 4” Exhaust Fan kit. The Kit was very easy to install and set up. It has maintained connection and has impressed me so far within the first week of owning it. I will comeback with an updated review later down the road and see how it plays out.

This was for my son again and I didn’t hear any complaints so I’m assuming it worked well

It does what's is advertised to do.

This is a brilliant product. I am extremely pleased. It's easy to set up, moves a ridiculous amount of air relatively silently. Installation was tricky though without adjoining rope hangers, so if you want to buy this you should pick up an extra set of those (the ones in the photo i had to buy extra). Also you will need something extra to connect the filter because it is not a snug fit (I connected with extra ducting I had laying around). Either way, if you have any doubts, don't, just buy this and thank me later. Total VIVOSUN fanboy now.

Great system. Whisper quiet and works great!

L'extraction d'air et puissante , et facilement réglable et programmable , elle fait presque pas de bruit et n'est pas très lourd ce qui permet de la suspendre facilement.

Ich habe vor dem Kauf etwas Recherche betrieben und mich dann für Vivosun entschieden. Bin von der bedienbarkeit gerade per App sehr zufrieden. Die Bedienungsanleitung ist sehr sehr einfach gehalten. Reicht aber gerade so aus um alles vernünftig zusammen zu bauen. Nun hoffe ich dass Vivosun am Ball bleibt und sich immer weiter entwickelt.
