My main concern is VENTALATION with both room i have a direct house ac line comin in the room and two 4 inch- 105 cfm Fans also jus some house fans i have done a pic of a rough idea of what i think it should be like

BLACK ARROW- AC LINE (Intake)

RED ARROW- (Exhaust)

Y ARROW- jus open lettin air in




TELL ME WAT YALL THINK WILL THIS WORK OR AM I GOIN ABOUT IT ALL THE WRONG WAY????

No one????????

You are going to need to remove the old dirty air.

In my situation I can just run my exhaust to my attic. Not sure if your setup has an exhaust.



My veg tent and dry box are connected to my flower tent




Hope this helps. Good Luck
