Hood ducting question

Discussion in 'First Time Marijuana Growers' started by Apocrypha8, Jan 27, 2014.

  1. So the light and hood and whatnot we got, theres two spots to connect ducting for cooling. which side do you use to inject the cooled air? the side like right where the bulb is blowing across and exhausting out the other side or vice versa?

     
  2. You want to pull air over the bulb, do not push air across it.
