How interesting, you can't tell from here that it's made of three different plants. Which one is the root? It looks like the longer it's developed the more the sections look like each other, or is that just me being inattentive?
On the other hand, I believe they're all sativas. You can see some minor leaf shape variation, but considering that they're all subjected to the exact same conditions, I don't find it so surprising that one can have a problem finding the borders.
