Phalaenopsis bellina mounted on slate

This is another ebay orchid that I acquired in early October. Unfortunately it arrived with a few little insect bites out of the sides of the leaves. It's been dormant since it arrived, but last week I transplanted it onto a rock mounted with some moss. Unless I am imagining it, there are the first signs of new root growth at the very very tip of an older root - it now looks quite new and green.
