Ok, so i have a small grow cab of 3'Wx2'Dx6'H and i need some good ventilation and maybe a small carbon filter. I want the smallest one (4") but I dont know the difference between centrifugal, inline, RK, Ruck etc. Also if someone could tell me how I should set up a carbon filter or just intake and outtake and what fans are the best/most suitable? As I am running a 400w HPS in there it will get quite hot so i would like to get something that really can keep the air moving.
