No i can't access the roof from where am at.
Yes i have two smaller yet decent air fans in my tent. One is blowing below the light under the plants. and one is blowing just in between the plant top and the light. NOTE this is only paprika seedlings. So i have not put my in my real seeds yet. So nothing is damages i notice the issue before hand.
By separating them I mean use a sheet of glass for instance and duplicate the effect of a cool tube.
Just a note, I've found that airflow without extraction actually raises my temps. Have you done a hot day temp check with the extractor going, but not the airflow fans?
