Cooltube w/ 6''-4'' reducer -passive Intake Question

Discussion in 'First Time Marijuana Growers' started by CnS, Jun 5, 2009.

  1. as I have said in another thread I hav a 2x2x4ft box. I have a 265CFM blower and will exhausting (pulling) through my cooltube and (pushing) into my scubber.

    My cooltube is 6'', I have it reducing down to 4'' to fit the flange on my blower, then from my blower to scrubber (6'' no reduction). My scubber core is 6''.

    With the 1.5-2x passive intake rule, should I have two 4'' intakes, or two 6'' intakes being that is the final diameter of the scrubber core?

    Opinions PLEASE got the last of the carbon i need and seting up tonight!
  2. I personally would go with the two 6".
  3. Thanks! I was thinkin that just wanted another opinion
