Just a question, what are the dimensions of the box, I can't really tell from the picture.

to save you fans, use the vortex fan to power the cool tube and the exhaust. let the cooltube intake be inside the box, and the exhasut of the cool tube attached to the intake of the fan, then the fan exhasut connected to the scrubber.
|cooltube|==|fan|==|scrubber|

yeah mrnicehigh, i drew up another design, it is just going to be like you explained with the cool tube air being drawn in from inside the room but i am going to use a "Y" connector to vent the room and cooltube like this
|cooltube|==="Y"===|fan|===|scrubber|
|cooltube|==="Y"===|fan|===|scrubber|

OK guys, this is what I came up with upon further thinking...let me know what you guys think... this picture is a little better to understand... I am thinking about doing it as shown with the scrubber where it's at or on the side, then sucking air out of the bigger room which houses the box to get rid of heat, or putting the scrubber in the attic, and just run ducting from the box exhaust to the scubber in the attic...the cool tube intake will be in the room... Please guys, I could use more ideas...Thanks

i would say keep the light horizontal and skip that "y" air duct because the light wont get cooled effeciently. All the air is going to be pulled threw the easiest way.

well the light will be horizontal, in a cooltube with a reflector, the picture is kind of misleadin about the light...it will be horizontal with cooltube and reflector, sorry about the confusion.... and without the Y adapter how am I going to cool the light?

run it straight to the light.
|cooltube|==|fan|==|scrubber|
the air that is being sucked into the cooltube is cooling down the room by sucking the hot air at the top out of the box, Its just running threw a cootube first.

The benefit of using two fans is that you can power down the light -cooling fan when the light is off. I'd say ( i would if i could) go with two fans. I feel like I am wasting power running the fan high enough to cool the light at all times.
If you go one fan as others are suggesting, get rid of the Y.
I'd suggest you move the filter inside of the box and suck through it. go filter>fan>light>outside. That way you won't get any dust on the inside of your cooltube or your fan.
edit: i just remembered another benefit of using two fans is that your carbon filter will have less air moving thorugh it so it will last longer and be more effective.

honestly...2 fans is basically out of the question, because then all the air cannot be scrubbed...unless i have nother intake for the cooltube...and...I already spend $200 on my vortex, not really looking to spend more...
P.S. the cool tube is only 4" glass...so i will have to use a reducer...I don't think that's enough airflow to cool the room through the cool tube...is there something I am missing about having the "Y" hookup?

That's cool.
As others have said, with the Y you will get very little airflow through the cooltube because the air will follow the path of least resistance and go throuhg the other branch of the Y. This will be ineffecient.
I think you are overestimating how much airflow you will need. Your 6" fan should be plenty. Even reduced to 4" I'd say..

i didn't notice where others had said it would follow the path of least resistance as you put it...now that you say that, it makes sense to me, thanks for clearing that up for me buddy...I am going to try your way first since that involves less parts and $...once again thanks guys!!! and I guess I will just have to live with the dust, I did it last grow, sucking thru the tube and it wasn't too bad...
edit: and your probably right about overestimating how much air flow, i have never had a fan THIS NICE...i used a room 2 room fan last time...lol...i know..

Yeah thats a pretty powerful fan.

goood, i should have no problem then!!!

here's the edited room...this look better guys?
and I'm still open for suggestion on how to hook it up with scrubber on the inside with air being sucked from it like you guys suggest...I just don't know how to set it up witht he light and all...

would a coffee filter or panty hose at the end of your cool tube eliminate the dust? I don't think it would slow the airflow much at all, or maybe even put filters over your intake to limit the amt of stuff being sucked into your cab
I've grown in a space w/ the same dimensions as you, and you'll def. have to use lst just about all the time, so get plenty of twisties and push pins.
About the scrubber, I also tried to build one and have the air pushed through it from the outside...BAD IDEA! Most likely it will cause too much backpressure and kill your fan, and possibly start a fire so if you do hook it up definately test it under a watchful eye and listen to see if it's working too hard. Theres a chance it will work fine, but they are way more effective when the air is sucked through them, and not pushed.
The only way to reverse it would to have it on the inside of the cab like you said. Heres an idea: radio shack has these 65cfm or so computer fans, about 4 inches, same as your cool tube...why not try using 2 fans like someone said, one sucking air through the cool tube and use the big one to vent the entire cab. I don't think they are too expensive, like 20 bucks or so and they work really well. You'll need a dc adapter to power it up.

if I run 2 fans, does leave dirty air somewhere exiting the cab, that has not been cleaned yet? I don't want any dirty air...How could I set it up with scrubber inside cab, and still be able to clean all the air?

with the two fan scenario you would have different intakes/exhausts for cooling the lights and venting the room. The two systems would be isolated from each other. This has many advantages but I think many people don't do it because it adds complexity.
The best way to do things with one fan IMHO is to have your carbon filter mounted to the ceiling inside your cab. go CF>fan>light>outside exhaust.
Here's why I think its the best way.
-Carbon filters are usually designed to be sucked through.
-Your fan won't be heated by the light.
-Your fan and light will be protected from dust.
-It's more stealthy to have the CF and fan hidden from sight.
