As IR said above, go with a hybrid that is known to stay short, yet, has the sativa dominance as far as bud formation and resin production go. The first thing that jumps up and slaps me in the face is White Widow. I'm guessing that it is around 60/40 Sativa/Indica. I you LST it, you can keep it short enough to stay in that cabinet. But your only going to have one, maybe two plants, maximum, in that small of an area.
