Just don't do it man. In the warm weather all that extra moisture will cause wood rot and black mould.

:peace:
Ok I will get back into the attic tomorrow and cut my 25 ft duct and make it as straight and short as I can to get it vented out my vents in the roof. Thabks guys for the feedback

So a 4" ac infinity fan. What's the max feet I should use that would give me full potential use of the fan?
Just as short as you can make it to get the job done. Stretch it out a bit too to make it as smooth as possible inside. If it can't be straight try to make the curves as wide as possible without adding a lot of length. 90° bends take up to 10%. If you do get a carbon filter get a bigger one made for 6" and buy an adaptor to fit it on. Much less restriction with the larger surface area and the filter will last for ages. If you don't need one so much the better.

If it's in your budget get a temp/humidity and speed controller for the exhaust fan. Then your fan only runs when needed and a lot quieter with the speed down half way.

Yes man that was my recent purchase, I have theb67 remote for the AC Infinity fans and I love it. I keep off mode on 3, so I'm always exhausting out and got each trigger setup. It'd a pretty awesome product.

As far as the run goes it looks pretty good. Does that vent open under pressure like a dryer vent or does the hose have a hole it fits in? If it's just blowing against the vent then some warm air is likely to be blown into the attic and you will get frost buildup around there.

Those timbers don't look like standard modern 2x4s so is it an old house that maybe has a chimney? I've known growers that vent into the ash box at the base so it goes up the chimney to get out. To me that would be a great solution. Wouldn't need odour control much if at all and no worries about a little frost at the top.
