how much plants per 1000 watt light

if u were to have 10 1000 watt lights and a room 24 x 24 and all the other good stuff... how can u maximize the amount of pounds grown? how much plants
will be ideal to grow the most amount of pounds of white widow and sour diesal (or how much plants per light)? whats the best spacing for growing in
this room? how much pounds would u be expecting? don't worry about the lighting cost or being bait* that will be tricked. and please add any tips or
secrets u may have for maximization of plants growth
WIll be grown in soil

rite now i figure per light there would be a area covered of 6 x 6 and 15-25 plants per light (which is better if it even makes sence?) which would make 9 6 x 6 and then save a light (and maybe add an extra light) for the 18 on 6 off room for germation, clones mothers seedlings and etc. this should total a 135-225 plants... how much pounds is that? and does this makes sense? any suggestions would be good
