My orchid has green roots but its media is dry do i water it?

What you are seeing on the roots is probably algae, which stays green even after the roots are dry. That can definitely be confusing. After watering thoroughly, watch the color of the roots, and hopefully you will be able to see a color change when the roots are saturated. The young ends of the roots should be the easiest to tell a change. What kind of orchid is it?
