ventilation in relation to quantity

  1. Been doing as much research as a can but couldn't find or decide on my needs. Dimensions are 3ftx5ftx8ft. Max plants are going to 6. SCROG method. Stealth is #1, then yield. I will dump heat and smell into the attic. I am going to use a scrubber or some sort. Do you think I can get away with a decent 4in inline fan to scrubber in the attic or should I go 6 in. I know obviously 6in moves more air but not sure it is required. I would also like to take noise into consideration. Thanks for taking the time to read this message. Cheers
  2. You should be fine with the 4".
  3. I would go with a 6 inch centrifugal fan and a fan speed controller this will keep the sound quiter because you aren't gonna have to max the fans RPMs to control the heat and smell.
    Also you forgot to mention what type of light you are using and if its air cooled which would be important info for this question.
