Indicas have wider, more rounded leaves, with a marble like texture and look, and a sativa will give you more thin lengthy leaves with no real texture to the leaves. Judging by what a lot of other people are growing (including myself), I think its safe to say this is neither pure sativa, nor pure indica. I would say this plant is a more indica dominent, but is definately crossed with a sativa only because the leaves show more indica and the plant doesn't look very lengthy, like sativas normally are. Now all depending on the time you harvest, you could potentially end up with IMO real quality nug because your getting the best of both worlds ie. the "couch-lock effect" from the indica mixed with the "head high" from the sativa. Either way your in for a nice treat, and chances are you've probably already smoked the weed! so if you liked all of the weed you smoked from your other half, you won't be dissapointed.
