This came up last discussion. It's actually easier on mars to do completely artificial lighting than concentrate, since the concentrators need to be about 3-4 times larger in area than the farmland would be on Earth, and are thus extremely bulky. Unless you can produce optical quality mirrors in-situ, it's probably easier to ship LED arrays.
