Venting thru cooltube

Seperate fan to cool lights? Or one fan to cool lights and exhaust?

separate is my vote. with separate controls.

Depends on your specific needs, no reason it can't do both if it has the power to do so. Even in a situation that requires multiple fans, I still might send them both through the lights and exhaust using either a passive intake, or 1 of the fans as an intake.

.. this is my setup minus the flex on theother end of my tube to direct air out. This should work just fine huh?

It'll b a dwc setup sog will be used.. 400w hps and mh.. 2-20 gal. Totes each containing 36-2" nut cups. Strains will be aurora indica and wonder woman, possibly swiss chs as well.. prolly just stick with the 2. Technaflora nutes n micros

yes that will work fine,

Good lookin man.. on the right side will be my mother/ cloning area.. I still have to install a shelf/ceiling, just below my ballast. Drill my intake and exhaust holes, fit that up. Clean up and transplant! Ill b rockin in no time

You will lose some major efficiency with the sharp bends in the ducting, but I've been faced with the same size/shape issues before and you gotta do what you gotta do. Maybe turn that filter so you have 1 less 90 degree bend? Not sure how you are on height availability.

6' in height is what I'm workin with.. I guess I could make it vertical instead.. it shouldn't interfere with my lights being raised.. hell they won't get much higher then they r now..I looked @ that damn box for hours and never thought about goin vertical with it.. thanks for bein my eyes @@
