Grow Setup, Input Needed!!!! 4x4x6

I'm just going to list my supplies and what not and you tell me if you think it will work or have any advice for me, I'd appreciate any input.

A 4x4x6 tent with all metal framing, including metal corner pieces.
I have a 600Watt HPS and MH in a cool tube with digital ballast, can modify fan and wattage.
For ventilation, I have a 240CFM Inline duct fan for exhaust that came with a 6" x 20" 500CFM rated carbon scrubber. A 7" basic clip fan for artificial wind and another 9" box fan for on the floor.
I will set it up like this: Carbon scrubber--->Light--->Fan>out.
Is this the best way to set this up, or are there better ways?
I plan on using passive intake, and the vents on the tent are plenty. 3 17.5" x 5" base vents, can be covered or uncovered.
Will this still scrub all the odor away?
Trying to grow 4 plants in three gallon pots, and 2 plants in two gallon pots.
I will use this tent for many different plant grows.

My nutes are fox farms trio, and soil is ocean forest.

The set up sounds like a nice system, except...
that inline duct fan will not be sufficient to move the air through the system.
I would definitely upgrade that booster fan to a centrifugal fan, preferably one with a speed control.
I have a very similar set up (see my journal) and the booster fan was not strong enough to pull the air through the carbon filter, and the temps in the closet were high.
When I ordered a true inline fan, the difference was instantly noticeable, and with the speed control, I can adjust the air flow to keep the temps perfect.
here is a link for a better fan: http://www.ebay.com/itm/4-6-8-10-COMMERCIAL-GRADE-Inline-Fan-Speed-Control-Hydroponics-Blower-Inch-/290927453266?pt=US_Hydroponics&var=&hash=item43bca0a452

Damn... I was really hoping I wouldn't have to buy anything else.... how high were your temps?

You will need to buy a temperature / humidity control unit. You can get a pretty cheap one for $50 or so. The unit will turn your exhaust fan on when the temps get too high or the humidity. This is a necessary component. Test your system for a day or two and observe if the fan can keep your temps within a desired range.

But yeah, you probably should invest in a centrifugal exhaust fan with a 7-10 year warranty to get the most desired results. Good luck, I have the exact same dimensions and just grabbed 10 ounces off my first harvest of 6 plants.

The carbon filter should eliminate all smell even at week 8-10 of flowering. 600 watt is appropriate for that sized room. Some people use 1,000 in 4x4's though.

The temps in my closet were at times over 100 F., but after the installation of the proper fan, temps are now mid-high 70s. The speed controller is set to a medium setting to sustain the proper temps, but I could crank it up or down if needed.
I will use the booster fan for my veg box, as it will not have a carbon filter, and will be smaller and less ducting.
