It's first challenge is the fact that not many people are familiar with it,and some of those who have heard of it think it's too complicated, something I tried to address with this post. Another one that I've noticed is a problem that Agricultural Extension officers usually experience when introducing new innovations to farmers, local and small scale farmers usually prefer to stick to known methods (in this case, Geoponics). Which is why you will notice that it is mainly practiced by corporations or large farms.
