i was just telling you how to get 200 in a room.
to vent you need 25 ft of 8 inch insulated duct. you will have a window in the room with a board over the inside of it. on the outside of the board is a hepa filter. you have 5 8 inch holes cut into this board, 4 for the duct, 1 for room airflow. attach 4 sections of duct to the board and to each of the first lights. The duct will get strapped to the bottom of the top bunks and to the ceiling. There will be duct connecting each set of lights for each bunk and duct going from each second light to it's own hole above the closet. In the closet you have 2 12" inline exhaust fans pulling the air from the outside to cool the bulbs. You also have one 8 inch hole cut above the door for the fans to suck air out of the room.
For nutrients use whatever you use. You can go organic or go all chemy. its up to you really.
