Anyone have photos of a starting vine?

for a while now I have had my N. inermis in the greenhouse and indoors, it is almost 8" high now, but the first 7" are smaller in diameter than the last inch, it has had this change in size in the "vine" area for a while now, I need to know if it is starting a vine or if it is just responding to the change in enviroment, does anyone have photos or explanations that might help me out?
