Stealth Wardrobe Grow 2

hey peeps, my last grow was a 600 watt grow in my student accommodation which was fun but a little on the risky side seen as i had a massive box in my room pumping out huge amounts of heat.

So this time im going to grow in my wardrobe that has the following dimensions

W 3.5ft H 7ft D 2ft

This time im thinking of using 2 250W CFL lamps with reflectors, and hydroponics instead of soil like i used last time. I just have a few questions before i buy anything.

1) Id like to grow the plants the full height of the wardrobe is this possible using CFL's
2) Would it be possible to grow 3 plants in the space i mentioned
3) Would heating and ventilation be a problem as the wardrobe stands about 2 inches off the wall
4) What would be possible to harvest 2 ounce a plant if i grow the the full height of the wardrobe in good conditions.
5) any recommendations towards my grow

Thanks in advance for the help guys

bump can anyone spare a hand : )
