For reference, i have a 400ish cfm fan on low and it can drown out a knock at the front door if i am in the same room as the tent. It isnt unmanageable on low, but on max, they reeeeaaaaal loud. The tent wont block the sound that much but may muffle it a tad. It all depends on whether you want to be more stealthy and be able to hear decently in the same room or if that is not an issue.

I have 3x3x6 tent with 4" fan and filter, and oscillating fan. Am going to get 6" fan and filter, but so far no issues, and it's been 9 months.
But then I'm stuck with 4" fan ( might use it in closet that I dry my harvest in)

Sounds good, only worry then is if it will be stealthy smell wise

Oval ducting is a good idea Poppa. Thanks. I have experience in most of the trades, but I'm an HVAC novice.

grouchyoldman Could you use oval ducting like this https://www.homedepot.com/p/Speedi-P...O-06/202907169 or is it a joists to close issue over height of joist issue?

Do any of you know if there is CFM loss if a 6" fan is exhausted through a 4" duct? I have a framing issue that makes 6" difficult.

Depending on light setup and ambient temps (which you indicate are not high) you probably will be fine. Since i live in the south, temps an humidity require a little more airflow but as long as temps and humidity are ok it should be fine to be just under the recommended CFM.
That said, I recommend getting a fan that is more than you need as fans on high tend to be loud. Having a higher cfm fan allows you to run at lower speeds decreasing sound made by fans, if that is a thing you care about.
