VIVOSUNAeroWave D4, 4” Grow Tent Clip Fan with Detachable Hook, 3-Speed Strong & Quiet Airflow, Adjustable Airflow Angle for Hydroponics, Circulation & Cooling, Black, 1-Pack

This is a great little fan. It fits perfectly in the little port openings of your grow tent!The opening on my tent are about 6 inches across.It pushes quite a bit of air for how small it isIt has three speeds and they are pretty considerable from one to three,it can get a little loud on level three level one pretty quiet.The directional grill on the front is really interesting. It’s set at an angle, no matter how you have it so you’ll want to choose left right up or down as a direction but if you want to spin just loosen the front knob a little bit and it spins all over the tent, which is really cool.Your options for hanging this tent or attaching it to a Small diameter pole on like a basic tent, but if you have a tent or a gorilla tent, it will not clip onto those larger bars.It has a nice magnet on the back that you could find a little metal plate to have it attached to the side of your tent or you can hang it with a string,The only downside I can find in this little fan is it has a USB plug but most of us have an extra power cube laying around. If you live in a different country, this would be an ideal little fan for you. You could plug it into USB that goes into whatever power you have.For the price it’s made well.I give it five stars for price and quality.

This is perfect. It's small enough to fit anywhere, and is extremely powerful for its size. The magnetic base is good and strong, and let's it rotate in any direction. You can even hook it up to a timer and it keeps it's speed setting. It's a lil louder than I expected, but it blows has hard as a fan twice this size too. Will definitely buy again, I should have bought two the first time. Lol

It looks really cheap but it gets the job done. I leave it in my small greenhouse. It keeps the air flowing but I can be loud even the weakest setting.

This fan is a do all type of fan. I love that it can be hung or attached to a pole inside a grow tent or a regular tent for camping. I use mine for both. This little fan in sturdy and puts out a lot of air for its size. I wanted to test it out before I bought more for another grow tent. It is a perfect gift to another grower or someone that needs one for a greenhouse.

I'm pretty impressed with the VIVOSUN AeroWave D4, 4” Grow Tent Clip Fan! It's the perfect size for my 2x2 grow tent and makes a huge difference in airflow. It has 3 speeds low-med-high, and it's pretty powerful for such a small fan. Plus, it's really quiet! The adjustable airflow angle and detachable magnetic hook make it easy to use and move around. I highly recommend it for anyone needing a small clip fan for their grow tent!

It blows but barely. It is so small, it moves minimal air. Go for the big one.

I love this little fan. It clips on to the frame well and it’s easy to install and adjust. It’s been running 24/7 for a couple months now and I haven’t had any issues. The quality is great, especially for the price. I definitely recommend.

Here is the disappointment you will have. Picture shows two fans sounds great dosnt it. Well guess what you only get one fan. The picture of this misleads you to think your getting a great deal your not only getting one fan with a USB power source with no block. Also the cable is not long so don't count on that. Sure it's a good fan for what it is but being mislead into thinking you are getting two is enough two make sure that you will buy another fan next time.
