Hi i will be growing in a 2 x 2 space do i even need a carbon fiber with a fan? i seen the 4 inch fan with 300mm carbon fiber is that too large for my grow room?

Late on in flowering you will need something to help with the smell:thumbs: As for the Fan depends on what lights your running and height. i have a 3x3x5ft and have all systems going lol :thumbs:

The carbon filter with an inline fan is meant to help with odor control. Also it exhaust the heat build up in the tent. Regardless if you are going to use a carbon filter or not you need air movement in that tent. Fresh air in, bad air out.

I can tell you that a 240 watt blackstar in a 2x2 tent completely sealed up will build up heat, I run four 240 watts black stars myself

Yes you will need one if you want to control your plant odor which is a serious issue if not addressed properly depending on how or where you live. Here is a link to what I am using in my 2x2
