Watering My Plant With Diet Red Bull

This is "Moose." It's a plant I received from a friend before I left Minnesota. He's grown a lot and I think that is in part because of my experimental watering habits. I figured he's a bachelor like me and therefore would like to drink the things I do.

Rumpleminze of course is out of the question, but he has responded quite well to old coffee. Figured I'd see if Moose likes Red Bull.
