good evening gc, i am planning on venting into the attic above my room. i have a few questions. i have a tent inside of a windowless room. there is passive intake into the room and the tent from the underneath the door to the room. the light hood is being vented out through the attic. as far as i know, the attic is sealed off. is this going to create a pressure issue? currently the trapdoor to the attic which holds the venting and fan is not completely sealed. i was planning on putting mesh around the holes to prevent insulation from coming down and to get some better airflow. so air should be able to be pushed into the attic, and flow out into and out of the room. does this seem like it will work? thanks for the help.
