I thought you were planning on growing it outside. Yes, AC does reduce humidity. If it is potted (use large bark) humidity is less of an issue. I would suggest partial shade - particularly at mid-day it needs protection from blazing sun. Remember, if this is what you want to grow, it's not a small plant. So if you can accommodate it outside, that would be desirable. If you are concerned about just protection indoors this winter, not a big problem, just don't forget to water it. Again, well-drained medium (lots of air) is the goal.
