This is a cross-section of a container. Most containers have a drainage hole on the bottom. I've marked that hole with an asterisk.

The problem with this position is that you have to elevate the pot with a stand and put a saucer under it or else water flow will be blocked by the pot's bottom forming a seal with the floor.
Can I drill the holes on the sides near the bottom so that I don't need a stand and saucer?

Is there a reason why nobody does this?
