I have a grow tent that's 4'x8'x6'6" it has various vent holes of different sizes I want to add an exhaust fan out one of the top holes and use two of the holes in the bottom as passive intake, my questions are what do I put in all the extra holes to make them air tight and light proof and what should I put in the passive intake holes to make them light proof and bug proof.
