Projector Tv Grow Box!! I need help with a few things

I made a grow box out of my old projector tv today,I must say it looks freaking slick. My grow area is roughly 3'1"L x 2' x 4'2" I won't have the full 4 feet for height because of the height of the pots and the grow light hanging down though. So about 3 total feet of height they can grow from soil. Now I plan to run a 250 watt HPS with cool tube hood reflector as to keep heat down in such a small area. I will use my mylar to cover all surfaces inside the tv. I plan to use one oscillating fan to blow the plants around and move air around. My biggest questions are,how do I run my cool tube ducting out? Do I want to have it pull air out of the tv creating negative pressure or push through the light creating pressure and should I have a second 4 inch inline sucking air from my room into it? My next question is how man plants in this size of an area if I top them? I am thinking either 2 or 3 gallon pots but leaning towards two gallon pots. I know I won't get much out of this setup but I plan to use it for clones after this grow. I have three different strains all femmed seeds,Super Skunk,Blue Mystic,Northern Lights. Which do ya'll think will produce the most and stay short enough for such a compact area? The 250 watt HPS I am buying is 33,000 lumens so plenty for this area I believe. So any thoughts comments or anything welcome guys.

Heres some pics of the stealth tv grow box I'm making. I still need to trim two boards and mylar coat the inside and get the fan ducts ran but it's coming along nicely.

Great idea dude,This is some real stealth the most unsuspecting shit i seen in a while,i wish i had a tv to do this with.

How about my 65"

Thanks for popping in guys and d3monic I got a lot of ideas from your setup. Thanks for popping in the thread I didn't see your set up,damn wish I had a 65 instead of a 55' lol. I'm having trouble deciding between a 250 watt and a 400 watt HPS.

Maintaining temps will probably be the hard part. Not sure if there would be a big heat difference between the two.

I don't believe heat will be an issue as it is only 24 cubic feet and a 270cfm fan for exhaust will pull a ton of air into the chamber plus my air cooled hood will keep the heat down too.

My biggest question is should I go for 2 or 3 plants in 3 gallon pots in this space? Also should I top or just let them grow normal? Since both the Blue Mystic and Northern lights are related and same heights I will be growing one Blue Mystic and either one or two Northern Lights.
