That would work fine for one plant.

Yes, you need light.

Try reading the growing forums here and the Hydroponics section here too for better answers.

To get any yeild though, as for lighting, it has been said that you need at least 50W of lighting per sq/ft of space, so look at your space, do the math, and see how much light is needed.

For one plant though, in a small space, I'd get at least a 150W hps bulb.

Good luck!
