Have a look at the phalaenopsis orchids in you local supermarket. You'll see the roots are thick without root hairs - often hanging out of the pot. The root outer layer is spongey/corky with the actual root hairs within. The roots absorb nutrients and moisture through this outer layer, which gives protection to the hairs.
