my idea for my grow tent

I want to be able to run 12 1-2 ounce size plants at the least under 1 1000watt so this is going to be my setup , tell me if you think its a good setup!
This would be my tent: http://www.virtualsunhydroponics.com/Agricultural/products/VS4800-48.asp?rt=2 4ftx4ftx7ft hydroponic grow tent with mylar lining and duct holes.
I have a 450 cfm inline duct fan , I want to get another one for exhaust.
Does anybody have any good reccomendation for a carbon filter that is good for that size tent? Preferably one i could buy online\in my local hydro store.
I have my 1000 watt and I can get 2 new HPS\MH bulbs easily. (if needed)
I would have one wall fan mounted.
Good ventilation , carbon filter, lighting , what else could I add? The tent will cost me
150 , im guessing carbon filter 100. I have the light.
Help?

You size the fan for the tent, then the filter to the fan (not the filter to the tent).
I am not a big fan of inline 'booster' fans. They can be loud & underperform their cfm specs.
A carbon filter to match 450 cfm can be big/expensive. Assuming you may not get 450 cfm of actual performance at the filter, you may look at a Can 33 (or 50).

How are you use the fan? to cool the light??
Are you exhausting right out of the tent? or are you pushing the exhaust out of the room??
I would recommend finalizing your exhaust for the tent, then sorting out your filter. Not sure where the inline fan would come in to the design. You may not need a boster fan, or an intake fan.

Bring air in , then have one to suck it out. Have the wall mount fan to blow on the plants to help the stalks and circulate that wind flow within the tent. My fan deffinitely lives up to its 450 cfm it is still brand new out of the box. Ive plugged it in to test it and it is probably the strongest fan in my whole household. Thing would cool down my bedroom like an AC .
