I am using 1000watt lights. I have decided to use two 465 dayton blowers. But I have 5 of the stupidest questions ever.

1.What in intake and exgust(spelled that wrong)
2. Do I have to put the blower outside or just in a window seal?
3. What type of ducting will I need to have the blower blowing old air out and bringing new ari in the cool off the lights.
4. Will this be good to keep the room filled with fresh air or should I buy more fans.
5. does there have to be lots of windows in the grow rooms for the fans?

Sorry about the stupid ass questions. I just want to have as good of an ventilation system as I can afford.
