    RobC Yes am using carbon scrubber, but I have a situation that enables me to vent.into the attic. So nobody.knows but me lol. And very little scent.in lung room. (Until I open the tent) and still not much smell

    Nice. Are you using a carbon filter? If so is effectively scrubbing the smell?

    I see, thanks for the reference. These AC Infinity are supposed to be the quietest ones which is why I chose it, I need stealth as in the sound can’t get out of that small bathroom tent is in. Guess ill put it in and test it

    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)
    I wanted.a 6" fan all along. I'd rather have more if needed, and wouldn't have to run on high. Although I've seldom run this one high.

    You are right, I’m worried I might have to run it at max but don’t know how loud it will be from inside the tent

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

    Thanks! If you have no issues why are you getting a 6”? What light are you using?

    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.
