Help setting up grow closet

So my friend sold me a 1000 watt mh/hps so I've decided to get a jump on my indoor winter grow the only problem the only place for it in my appt. is in my bedroom closet it's one of those double sliding doors it's a 9ft high 7ftlong an 3 feet wide is this too small of a space for a 1000? its been 3 days and I'm having the hardest time with heat I've finally got the temp near the floor 85-88 but that's with a 3ft window box fan in the door with it open see pic I kno when I flower I'm gonna have issues I'm already planing on aninline fan but u think that will do??? I also took my central air vent in the celling an hooked 6 in duct an ran into the closet buts its not really practal to run it constantly so I'm trying to figure out something before flowering to keep temps down in such a small area any ideas would help greatly

You need an exhaust fan up high, not on the floor, and if at all possible exhausted outside of the insulated areas of your house, be it out the window or even punching a hole in the ceiling like a bathroom vent.

Edit: Oh wait, you are in an apartment. Scratch the hole in the ceiling idea. Bad idea.
