controlling odor question

I'm going to be doing a single white rhino scrog and need to get my odor controll in place first.

I just need some links to a few sites that sell good cheap carbon filters, yes I could build one but irather pay for something that will work best. AND A INLINE FAN

As I live in a apt and I can't have smell leaking out.
I was on phresh filters.com and for the 4" x12" was like 90 $ and the 4" inline fan was like 150 I think.(I'm using my phone). So icant check the price .

I'm posting in the newb section bc I feel that's what this is.

So please throw some links my way
BTW my box is only 2l x 2w x 4h. Yes I can make it bigger if need be, but just giving evrybody a ider of how big one of my boxes will be

Thanks I think ill go with the cheape 120 fan and filter ....hmm now I need a light I found a 1000w hps on craigs list for a 100 buck but he sold it already..
Trying. To spend money wisely because cheaper isn't allways better I figure since that the light is one of my hearts to my grow I wanna buy something that is worth the money that won't break after a couple months of lots of use.

And is better for the plant

Craigslist is the shit for hydro stuff in my area.
I would say when it comes to lights the ballast and hoods are all the same, its the bulb. You wanna get that new and only use it for a couple grows.
