Carlo,
There may be a physiological difference in roots. However, once the aerial
root reaches any material that it can grow into and extract nutrients, it
wlll do so. I have plenty of aerial roots in the shade house. When they
reach the ground or when I take them and turn them into a pot they
immediately spread out and become nutrient gathers. Aerial roots are just
searching for nutrients and when they find them.... Sure, aerial roots
have a different epidermal layer than ones that are in potting media but
that is only because they are in air and not in media. But, when they find
some type of media... they change.

Quite frankly, I like them hanging out also...
