I'm just going to talk from personal experience.
Firstly, you will have to cut the plants.
My last one almost grew to 2m, and you need a lamp about 3 feet (1m) away from the plants or they will burn.
Theoretically its possible to use only one lamp for this, but I'd personally use 2 if finances allowed for it, at 2m intervals.
as for how many plants?
depends on what your aiming for, if your aiming for one big grow at a time, quite a lot of plants, to be honest, I'd say about, 25 safely.
So I'd start with 50, judging that by the law of averages, 25 will be male and 25 will be female,
Judging as you stated your measurements in metric I'd hazard a guess your english, although I could be wrong.
You havent spoken about any windows or anything, so fresh air and circulation would be a big issue.

sorry mate, firstly, I hate paint, I will do it though, more importantly though, I need more detailed schematics.
Where is the window in your picture?
Where is the door in your picture?
Can you drill holes in the walls / ceilings.

If you start with 100 plants, you will need different lighting, as I dont think you can lower the hps low enough to provide ample light needed for seedlings, also, from my experience seedlings work better with lower light, things like "mini fluros" or fluro tubes are better.
Nutrients: Don't know.
HPS lights that ship continental:

I got my HPS from them, also the ballast apparently operates MH and HPS!

If you can afford to buy some air cooled cylinders, do it. If not, make them, find out here, www.overgrow.com
Hook up some ventilation ducts through your lamps, Ive never done it, but Ive read about it..
tells you how to do it on overgrow.. run air in, and air out..

You'll need duct fans leading outside somehow to bring in fresh air.. blowers, something to get the air in, and the air out
www.insidsun.com or www.discounthydro.com

As for vegging small plants, you will probably need less powerful lights.. those are way to high in heat to keep close enough to your plants, I'd say they'll grow, but not at full pace and you will probably encounter problems..
