Advice for grow cab/tent

Ok i want to start growing soon. I have been reading the forums, books, and watching videos. I have an idea for my cab setup but i would love some advice and maybe some tips especially on ventilation. I want to use this grow tent which is 20" X 36" X 64" and has 32 cubic feet. High Tech Garden Supply
I'll also be using a 400w hps with a cool tube and a vortex inline fan but I dont know what size yet. One thing i havent figured out is how im going to setup the cool tube and carbon filter. Should i have one fan for both or seperate fans for each. If its for each how big of a fan for the cool tube?

anybody?

i use 400watt hps
i dont use anything else but i do have a window in the room and it's winter at the moment

idk why no-one else has responded stinky is usually very helpfull

just stay patient someone will help ya eventually, i would but im a nOob also

ok cool thx

basically from what your planning on using i dont think you'll have a problem with ventilation if you get a second fan for the air space.
the use of the cool tube will keep you temp down drastically
you might also consider getting a digital ballast

o sweet that was my biggest concern was the ventilation

on further examination of the grow tent i realized that it does not come with any fans.
you will need an inline fan for the cool tube, an inline fan for exhaust, and possibly one for intake.

if your goin vortex fan i just bought from here and their cheap too
Vortex 6 inch Inline Fan 449 CFM - Plantlighting Hydroponics
thats all the fan you will need

to set up go open 1 side of cool tube, exhaust hose on the other connecting to the fan then from the fan another exhaust hose to the carbon filter
you will want the fan to suck the air out of the grow tent and blow air out the filter

hrm....
so the cool tube is open at both ends and the fan is so powerful that it sucks air from the growspace through the cool tube and out?

no open on 1 side hooked up with exhaust hose on the other
