Any chance of growing anything in here?

I've never relied on passive intake, nor do I ever plan to - worst case, grab an inline duct booster fan (axial, not centrifugal) - they run cheap and quite quiet - airflow isn't much, but you don't need much with the negative pressure you'll have.

Check out my videos on Youtube for a feel for how loud it gets in my garage.

Ill just try out two 4" vents in bottom left then, see how that goes, then go from there if temp issues arise.

In terms of noise I could go with these fans instead of the RUCK ones mentioned above...

They are said to run silent, however the 4" version is only 130m3, where as the RUCK is 285m3. So the quieter one isn’t going to be powerful enough?

As all the extraction is going to be in the top section I could just try and extensively sound proof that section of the wardrobe? Although just viewing you videos, thats going to be easier said than done

Lol, yeah the sound's a bitch to handle (although I'm getting some of that recording studio foam pretty soon, which should help out).

As far as the fans go, I'd make sure your ventilation's cool to start, and then worry about sound later - not sure if those fans are gonna get the job done, I've never used them.

Perhaps someone who's used them could help you out?

hi bob, the idea is to have some cross flow, air in low and from left, air out high to the right. understand the goal? and yes use 4 in ducting . you cant leave holes because the light will come out. if possible put fan in attic and run a duct to the grow area so you don't hear it. and remember fans push better than they pull so put fans at the the ends of ducting with little to no ducting on the intake side of fans.

Lol............yeah, I think I get it - thanks so much for clearing that up for me; I'm really a noob when it comes to ventilation .
