1 plant light suggestion

Here is the scenario:

1 plant
3'4" tall
Sparsely taking up 3.5 sq feet of leaf coverage.

The space in which it will be held is a closet.

3x3 sq feet by 5â??6â? tall

What is a good light source that will accommodate these specifications?

I figured my 600w is too big, so Iâ??m thinking 250w hps on the top with some supplemental fluorescents on the side.

Iâ??m not trying to spend a whole lot of money, so what are your suggestions?

And, does anyone have experience with the all in one 250w hps systems?

Thank you
