is my yield master hood set up properly? with pics, help

i bought a yield master supreme cooled hood and i dont know if i set it up properly im a noob just learnin as i go along..

i have my intake fan pushing air thru the hood and out the room directly out a camoflouged winow' opening but i dont have a fresh air intake ... any advice on exhaust setups? thanks (see pics)

Well you will get rid of most of the heat in the room, if your not going with CO2 you will be fine, just watch that your humidity doesnt get too low.

welll its only my veg room so i dont need co2 do i ?... what if i disconnect the fan put some more hose and put the fan outside the room on the other end so its just hosing on bothe sides of my hood? get me? ..it wouldnt circulate any air in the room but maybe would that keep more humidity in the room?
