if you want to reduce 8" just clip the wire in two spots, tape half the duct down pull up the other half and tape that. also cut a few inches of insulation out at the end then pull the end of the wrapper down and tape that as well. looks much better than having insulation hanging all over the place. |
I'm not sure what you mean by " If you blow that big fan through 6" duct, it will only flow as much as the duct can handle.. so you might as well have bought a smaller fan."
I will be needing a 6" inline fan for my Veg cab, and an 8" for my Flowering cab. I was under the impression that 6" ducting went with 6" fans, and 8" ducting went with 8" fans, no trouble. The reasons for the duct reducers would be to eliminate the need to spend money on 6" ducting, since I won't be needing much for the Veg cab.
So I'm guessing if I use 8" ducting for a 6" fan, the airflow should be pretty much unrestricted?
