alright here is the way that i have found to be most effective for ventilation.ill post pics of my setup if you have any questions let me know....in my 8x8 room with 6 lights my temps stay at 79-82 with CO2 as well....no ac in the winter...i just use fresh air ducts from outside....I only use one 8" fan for this but i am thinkin bout upgrading to a 12" fan....with this setup you will only need oscilating fans inside the room....you will notice the walls sucking in greatly....this is normal if your room is well sealed...even with the intake tube....this setup has worked for many rooms....you could hook up your cool tube exhaust ducts to the cardboard box since it make enough vacum for the room and then some
