What size extraction fan for ds 60 ver2.5 tent

Hello all!
I'm trying to figure out what size extraction fan and carbon filter size to pick up, I have my eye on a 6" ruck fan ( low power version rk150l ... Would that be over kill for my small tent also could I use a plug in dimmer to slow it down??
Size of tent is 60x60x150. Thanks!

Edit... I'm using a 250w hps , also heard that a 4" tt kit is pretty standard and once the carbon filter is on the air flow is reduced by 15/20% any views on this ???
