wonder what the difference between construction sand and **play sand**.

Play sand is too fine. You can also use pool filter sand or chicken grit.

I also have a beautiful ceramic pot with no drain hole that i would like to
use to plant an haworthia or Christmas cactus

Take it to a tile store or stonemason and have them drill a one inch hole in
it.
