Typically capillary action is the enemy of drainage.  The most extreme
example is bentonite clay formed from extremely fine airborne volcanic ash.
The capillary action is so strong that it is used in geo-fabrics to line
waste sites to prevent water exfiltration.

Normally for my purposes, and in my climate, I want maximum capillary action
through my pots and into the surrounding sand.
