VIVOSUN AeroWave D4, 4" Glow Tent Clip Fan with Removable Hook, 3-Speed Powerful & Quiet Airflow, Adjustable Air Flow Angle for Hydroponics, Circulation & Cooling, Black, 1 Pack

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

Perfect for a small grow tent. I got a pair. The magnetic placement is a game changer. Can't recommend strongly enough. Quality kit. But, get a long usb to usb cable - i, i think got either a 3m or 5m, so I have plenty of leeway. They don't come with the fan, so make sure to order those too. Standard USB cable you'd plug into your laptop, but with the same connection at both ends. Very many have multi ending connections, i.e male to female, male to usb-c etc. So be careful about this. I hope this is clear. https://www.amazon.co.uk/dp/B0080HAYLK?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

Convenient to position in multiple ways, get in awkward areas, lightweight, powerful, fairly quiet…

Amazing little fan will be buying another soon

Excellent fans that move a good amount of airflow in my 2x4 tent. I havre one under canopy and above. They work great and are well worth the amount 👍😃
