Hey Zoid!
If you have a powerful exhaust fan, you can forego [sp?] the intake fan... as the exhaust fan will create a vacuum.... which will pull air IN through your intake tube.
Passive intake is what we call it.

There's a good thread in the.... here

It's Mellow Man's cool tube How To.

Being inspired by him, I did my own:::

RE::: Jamstigator's cool tube setup.
Yeah, the venting is necessary.
I'm sure the open-end of his cool tube is the intake, and he just pushed air outside the box.
That's the idea... to keep all that hot air the bulb produces, and keep it separated from the grow box's enviroment.

As to the 6ft drying machine duct going to the wall/box, that's the thing I was guessing.
You're going to end up with two or three wierd stuff 'out of place' in your room.

BUT, if that's the "box" room... and it's the computer and the grow stuff in there... Go for it!!!

Wise Words::::
It is better to say you're sorry than to ask for permission.


Let us know how it goes man!
