I'm adding a thing. Get a programmable thermostat. It's $40. Hook your exhaust fan to it, and set it for 75 degrees (mine go off at 73, and on at 78). Change that number, if you are in winter, or summer. . .these plants do fine as long as their range isn't huge. You can flower at 80 degrees, or 65.
okay, enough typing. hope this goes amazing for you. if nothing else. . .you'll have the right gear. especially the right light and a reliable inline. that's 90% of worries.

Also, definitely get a fan speed controller and set that baby at the lowest setting. These guys can really go and you're not gonna need all of that CFM for such a little tent. The key is that these fans can create higher pressure (to overcome the resistance of the filters) at lower CFM (to not turn the whole room/closet into a wind tunnel).
If you then hook up the fan to a temperature switch it'll only run when the tent gets hot enough. This will save energy, create less noise, and also avoid creating temps that are too low at night if you like your apt to be cooler while you sleep.
This is all way more info than you asked for but it'll be a really nice, easy system and it'll work with any size tent if you decide to go bigger in the future.
1 plant per pot. I'd go 3 gallon pots. Smart pots are great and harder to fuck up.
165 Cfm 4 inch fan would work well. I use that in my 4x2.
Edit. This fan. http://www.amazon.com/Active-Air-inch-Line-Fan/dp/B002JQ4N92
Edit edit. That light is only 200 true watts. You need around 400 watts for 8 square feet. You tent is 4x2 and that light is good for 2.5x2.5. I'd look into a 400 hps/mh combo.
Im not really a fan expert, but I still think that company is making up bullshit numbers for their filters CFM ratings.
Heres what I went with - Fan, Speed Controller, Carbon Filter
Nice! You won’t be disappointed. Good luck!!!
Just an FYI - it looks like the 135 is a lit you have to assemble and the actual light board is the same wattage as the 100. Either way you’ll be happy.
The HLG 100 was fully assembled:

Last bit of advice - if you’re going to get a exhaust fan don’t get the Vivosun. I love their tent but the fan started making horrible noise after 17 days. They were cool about the refund but I went with:

It’s not a variable speed though but at least it’s an even sound. Like a window AC unit. Maybe a bit louder.
