the leaves are very narrow like sativa so I think you're 100% correct. I expected a very small plant(2.5feetx2feet at most) but luckily it was the only female so it's got the entire flowering area to itself. Another stroke of luck is the fact that it's being grown within a shelf frame. There's a pic of the shelf rack attached

The only shelf on the rack is the top shelf which the light hangs from. The rack allows me a very easy way of attaching supports to the plant. The plant has 4 tops that are the same height(approx 5 Feet), and another 2 that are slightly shorter and then some other riffraff below. Because of the node spacing I'm not expecting dense buds, but the overall weight should be pretty good.

Another benefit of this extreme verticle growth is that I have absolutely no guilt about taking the young flowers from the bottom of the plant because at this point they get almost zero direct light. I wouldn't want to smoke it all the time, but every once in awhile I do enjoy the spacey high of the very young flowers.
