Here's a picture of my duct work. Just wanted you to visualize what I have going on:A few weeks back I compared the Alu Ducting from 2 different local hydroponic stores. One came in a box and was branded and had clips the other came without box was unbranded and looked cut-to-size. The boxed/ branded Alu Ducting was a much higher quality with far fewer holes. .... I moved the holey ducting onto the 'expel' side of the fan.
..... I have seen round PVC flexible ducting. Obviously this will have no holes. I see this product everywhere online but have not heard of peeps using it in their grow-rooms, I dont know why.
Insulated duct are a pain in the posterior, they are big, cumbersome and quite difficult to fit as well as 3x the $
One thing on tape .. Gorilla tape is too thick for sticking ducting. A thinner more flexible tape works best.
Edit:
I just want to say that although the ducting may look like a christmas tree on the inside. I'm unsure as to how much this will contribute to any odours. ... If you were to combine all those tiny holes into a single hole, it would be unlikely that they would be any larger than a dime. ... would this really make much of a difference?? .... I mentioned the tiny holes previously just to draw your attention to it. I wouldnt worry about it but would focus on other gaps elsewhere.

Out from the light and back into the tent:
