Fluorescents/400Watt MH/1000Watt HPS

If I wanted to minimise grow room assembly and wanted to enable the possibility of a quick take down using the spare room in a rental property, is a 1000watt HPS kicking out enough lumens to avoid the need for elaborate reflection. The Fluorescents for cuttings and 400 Watt MH for veg. growth I will use in the built in wardrobes. I know it is best to optimise as much as possible but maybe 10 plants all under the main beam of the reflector and adequte air circulation is enough to still produce high quality yields with other variables taken care of attentively. I am concerned about that short notice house inspection and need a quick dismantle back up plan as I have only used lofts previously.
One more thing, I also don't have the ability to attach inflow and exhaust fans into the walls as its a rental, will using supplemental CO2 during light periods, an air cooled reflector and moving the air around suffice for ventilation?

No, you need to decide how much marijuana will satisfy your needs and work backwards.

As much as I can yield off ten. I am tempted by SOG method but paranoid about take down. The first 6 months are the safest right so I am in two minds whether to go all out and then reduce or keep plants to low number for quick take down.

I have also narrowed down the possible rentals with good spare rooms. I am willing to invest in any useful items with no costs spared, I just would like a quick out if needs be. How much do I want?
