Most efficient fan and air flow ideas for a 4x4

I'm seeking ways to have generous airflow in a 4x4 without wasting excessive power using the wrong fan.
I was surprised that my 20-inch box fan consume 1 kWh in about 2 days.
And the little fan purchased from the garden shop doesn't move much air, even with the grill removed.

Have y'all experienced folks determined how to get the most airflow for the dollar in a tent?
I bet there is a creative solution out there!
Or maybe I just need to get pointed better higher fan quality that is more efficient.

Thanks!

You talking circulation of extraction?

1kwh is only 20w x 48h , which is nothing. Its also 17pence and probably a damn site less if your in US.

Thanks for asking to help clarify my intent. I was primarily interested in circulation.
After watching the wind blow branches of small plants outside, I figured I'd put my 20-inch box fan back into the 4x4 tent. :-)

Seems like OP got his answer so I’ll figured I’ll throw my question in here instead of making a new thread. I have a room that I can’t really vent outside or bring fresh air in. So I have to focus on just good air circulation in the room. I have normal house fans blowing in there but looking to replace 2 of them with a more powerful fan. Any advice for a larger fan for a room grow

This is one of my setups. The other is the exact same on the other side of the room. I use an ac filter on the right side to allow fresh air in. 2 clip on fans 1 for each light. On the left is a desk fan I got at Walmart for 20 bucks and it rips. Not in the picture is the terrabloom 4 in in-line fan and it’s super strong and has a remote that controls the speed. I also have an air purifier just to make me feel betterC8C3C6AE-3542-419A-B9DF-2A5967BFA059.jpeg

I don't even have any small fans in my tent. The airflow I get is from a 6" 400 cfm fan on a speed controller pulling air through a carbon filter at the top of the tent with filtered bottom vents opened for passive intake. I don't have any fans blowing on my plants. The air flowing through the bottom vents into the carbon filter and exhausted out of the tent provides all the airflow needed. I had a small fan blowing between the light and top of the plants but it started making a bunch of noise so I took it out a couple of grows ago and never replaced it.

I use mine for the lights because it’s in a garage and to control the heat the lights make and these keep them cool to the touch. Being in a garage the sound it makes doesn’t bother me
