If you can reduce the length to half or less than that, I think you would gain extra horsepower out of your fan(s) resulting in some lower temps. If you can replace the flexible to whats called 'warm air pipe', using as little bends as possible ....that would be much better. The best you will be able to do is about 10F above the ambient temperatures being pulled in. That means if you're pulling in fresh air at 75F, then you should expect about 85F in your grow space.

So far so good. No problems with anything yet. Grow room temp at its highest is 82 degrees, and 75 at its lowest. Part of the problem was not having the exhaust fan ducting air tight. I fixed that problem and introduced the plants to their new home. I got the temps just right because it cooled the light, and adding the water cooled plants increased the humidity as well. I will keep your ideas in mind if my temps go back up. Thanks for all the help guys.... pics coming later today.
