Need Help upgrading Closet Grow with Ventilation fan, flextube, and carbon scrubber!

I just finished my 1st indoor grow. Actually I am almost finished. I have harvested 2/3 plants. My Super Lemon Haze is in jars curing. My Pineapple Chunk is still hang drying. The PC should be ready to be put in jars later on today or tonight. Tomorrow morning at the latest. Ever since I have harvested my Pineapple Chunk the odor of that plant has become so strong that you can smell it outside. There has been a smell but it has been contained inside my house until now after I harvested the PC. When I harvested the SLH it didn't stink nowhere near this bad. Then in 3-6 days I will harvest my White Widow which doesn't have that strong of an odor compared to the other 2 strains. Who knows what to expect after I chop and hang that baby out to dry. I hope that it doesn't stink like that PC has.

I have been growing in my closet under a 400w HID light system. I didn't have anyheat issues, so I decided not to get an inline or exhaust fan and a carbon scrubber. I'm not familiar with any of that stuff, so I am asking you all for help! My closet is over 7' tall. The closet is 61" wide and 22" deep. What size inline fan or exhaust fan would you all recomend for my space. I'm only doing this for odor control so keep that in mind. Please explain your answers so that a newbie can understand it. I don't know where to place the fan and scrubber or what kinds to even get. Help me please and thanks up front!

Here are some pics of my closet with my White Widow in it today that I just took.

C'mon people, there has to be someone out there that can help me out.

Going through a similar issue, what I did was get one of those DuPont air filters with the odor control and activiated carbon embedded. It's for pet odor control in homes. It comes much larger than most homes need (at least my home unit) so I installed it as directed and had a bunch left over. I simply folded it up and put it over the intake of my cooltube (the fan pulls from the other side and exhausts into the attic). It's been working fabulously. I doubt it will stay charged through a whole grow but for the last 2 weeks and drying it's perfect. It's under 10 bucks at walmart.
