VIVOSUN AeroWave D4 Grow Tent Clip Fan with Detachable Hook, 4" Fan, 1-Pack

These are great little fans for small environments that don't need cyclone-force winds, lol. They are also very reasonably priced for what you get, so I've bought multiple units now. They're not as quiet as I had hoped, but they are quiet enough in the environment in which they've been used that I am still very pleased. I tried to use the oscillation feature, but it was a little bit hard to adjust so I eventually gave up on that. The flexible mounting options have been extremely convenient, and their light weight makes them easy to use pretty much everywhere. I'm not terribly pleased with having to provide my own USB power source, but I suspect most of us have a few laying around so it wasn't the biggest deal. Overall I would recommend them, and intend to buy at least one more.

Nice little tent fan. It’s quiet and just enough power with 3 speeds. Pairs well with the 750mL humidifier by Vivosun.

I don’t usually write reviews unless something really impresses me — and these fans absolutely do. I now own six of them and use them daily in my garden setup. They’re incredibly quiet, even at the highest speed, and the airflow is surprisingly strong and customizable. The fans are very well made, durable, and are nice and small so fit in my greenhouses perfectly. The adjustable hook is genius — I can direct airflow exactly where I need it. Between the multiple mounting options and the angle adjustments, I’ve been able to set them up in tight spots, on poles, and even in grow tent corners. They’ve made a huge difference in temperature control and airflow for my plants. The one-touch operation is simple, and I love that it remembers the last speed setting even after a power interruption. If you’re looking for a reliable, whisper-quiet fan that punches well above its size, this is the one. I can’t recommend it highly enough.

This is a palm sized fan. It has three speeds and the third level is pretty impressive for the size. I definitely need a larger more powerful one.

I had a lot of hopes for these fans but after using them for 2 months I’m not a fan… When I first unbox them I was very happy because it’s solid and well made. They are loud even when I have the lowest setting so sometimes I stop them - if they touch the shelf they vibrates and makes a humming sound, so I’ll have to readjust. The magnetic clips are nice and strong BUT its angle are pretty fixed and not easily adjustable - you gotta find a spot that works for the fan instead of putting the fan that works for you. I bought a cheap computer fan for another grow tent and it works MUCH better for half the price. The quality of the computer fan does not feel as good but it’s lighter and has adjusting fan speed so on the lowest setting you barely hear a sound. These fans only has 3 settings instead of a dial so less option to adjust - I never use the higher speed because the sound annoys me a lot. If you have a large grow tent that’s not in your work space maybe it’s a good option as you may need a more powerful fan for it and the noise won’t bother you. But if you have a smaller setting like a plant cabinet in your living room or office I would not recommend this product. Honestly it’s a one star product for me, but given that this is a well made quality product I’m leaving it 3 star, as I see that it’s built for a specific use ( grow tent, as its marketed) and I could imagine it would work well. So it would be unfair for me to give 1 star, just that this is a highly recommended item in the plant community so I’m giving it a neutral comment to highlight the issues when used in plant cabinets

These are currently the BEST option for small circulation fans on Amazon's marketplace, imo. I love all of the different mounting options and that they have 3 adjustable speed settings. And the optional rotating faceplate for an oscillating effect is genius! Just twist the front knob closed tight to turn it off, or loosen to activate the spinning! (See my vid). They do NOT include a power source. And you need a more powerful than average brick to get full power. I purchased a dual-port 12W USB charger brick for each set of two. I got 4 fans total for my propagation shelves in my greenhouse. Install setup: 6ft long shelves with one fan on each end of each shelf works great using medium to high power. My plants love the airflow which helps with their growth and helps prevent fungal issues. They feel very sturdy and are worth their price.

Had for about a year but didn't use much because another fan I have moved air much better. Anyways it stopped working after about 5 or 6 hours so not worth it for me. Also the airflow is pretty weak even on high. I have a 3×3 and I could barely feel the air on the other side of the tent. Boo.

Great little fan! Very quiet and the magnet on the back is so useful. Really kept the air circulating in my laundry room nursery.

Gewoon zoals geadverteerd! Snelle levering! Compatibel met de Vgrow

Fonctionne parfaitement, petit mais plutôt puissant. Un peu bruyant en vitesse maximale.

Bester Support den man sich wünschen kann. Eines von 2 Lüfter hat einen leichten Unwucht.

for the VGrow it perfect and perform as it should ... for a really small tent or growbox i wish it could rotate and escalate to distribute more air

Hasta el momento me han servido excelente, llegaron muy bien
