you would need a lot of fluorescents to have 4-6 good sized plants. Not worth it IMO. 250w HPS only covers 3'x3' primary and I think 5x5 secondary. Don't ask me the difference, but I assume it just means the buds within the smaller space will be better than the edges of the light window.

I'm pretty sure that 250w HPS has a lot more lumen loss than say something like a 400-600w. 16" away from the bulb is about maximum for good flowers from a 250w. If you just want to grow a personal stash you should just grow like 2 plants with a cfl setup.
