Preventing noise travel from a hanging inline fan

Any new ornamentals will be kept in another part of the house until we’re double sure they’re clean. She’s into propagating for resale and has good reason to ensure everything stays clean. I wish I could say the same for the orphans she keeps dragging home. We just finished paying $3g’s to have the entire yard re-sodded and I’ll be damned if she’s not out there digging phucking holes everywhere for these things she just can’t not drag home. We have this long standing battle over the meaning of the word weed. By definition, a weed is any plant that is objectionable where it is growing. Hence, I keep trying to tell her that if it’s not something I can eat or smoke, it’s a weed and should be treated accordingly. Put the mower to it and be done with it.

As you say, back on topic -

I went with an 8" fan for two reasons. One is to ensure that I have well more air pushing capacity than I need, and the second is the ability to run the fan at lower than rated capacity to help keep the noise down. I have no illusions about having a quiet system. As I said in an earlier post, I have this aversion to vibration type noise traveling through the house since it’s largely avoidable.

In all of my years working in HVAC I’ve never seen flex duct with a smooth interior. Can’t see how that would be possible. About the closest you’ll find is flex that has sound deadening material on the inside, but even that is going to cause restriction.

Thanks. Building a dedicated indoor grow room is a lot of work, and my work is long way from being done. As in months. I’ve spent an awful lot time considering the tent(s) option, and I’m still not convinced a dedicated grow room setup is “the” way to go.
