to cool HPS do I push or pull the air through?

  1. I'm getting set up for my first grow and understand that inlines are more efficient pulling air through the filter rather than pushing it through....so.... I have a separate inline for cooling my 600w and I'm just wondering if the same logic applies here pull air through the air-cooled hood or push it through? Thanks :smoke:
     
  2. Pull.

    Think of it this way. If you push air into an enclosed system, it will leak out all of the cracks creating positive pressure in the tent. If you pull air out, you create negative pressure, which means the tent is pulling in air from all the cracks, which is exactly what you want.

    suck not blow
     
  3. Thanks RongBip I will pull the air through my air-cooled hood NOT push it. Thanks for the advice.
