, Yes, each of those pots has a single drainage hole in the bottom of it.

I simply water them from the top until water flows out the bottom of the pots. Then I wait several days to water again. In the summer, it's usually 4 or 5 days between waterings. In the winter, they can sometimes go over 2 weeks before needing water. I just stick my finger down into the moss a bit to ensure that it is still damp beneath the surface. Once it starts getting more than an inch before I feel moisture and the pots feel light when I pick them up, then it's time to water.
In the very bottom of the pots, there is about 4 or 5 inches of peat/sand/perlite mix which helps hold the water longer and better than just pure long-fiber sphagnum would.
