u can go fluoro or hid lights...its really up to u, the main dif will be the results...fluoros are chepper and suck less power then hid´s but metal halide and high pressure sodium will give u a better yield....remember that 4 u to have 10 plants u will need lots of light and a nice grow area (unless u´re doing sog)...10 plants at least a 600w hid bulb imo
