Fan on oscillating or standing still in dry tent ?

[bguwop420]

I had it on oscilate last time but I think my buds dried unevenly, right now I have it in the left corner when you open the door pointing straight back at the wall, would that make a more even dry just having it in one position?
Exhaust fan also running at top

I use a fixed fan. Do exhaust but only to keep my tent at 60% rh. My area is super dry 15% rh. I keep a humidifier in my tent to help keep humidity up
