Or: The sub-surface irrigation technological device
Ollas. Oi-Yahs. I know, I said, O-lahs, at first, too. But, that’s wrong.
The Spanish settlers brought the first ones to the Southwest, but let’s face it, the native American Indians had been using pots for years. And, that’s all it is. A pot. A porous, terracotta pot. You chose what you want to do with it.
I found this statement on Etsy: It is an emitter, that is buried under, or near a plant's root system. It makes an osmotic field, of moisture underground.
It's a buried porous pot that waters your plants. Nothing more. And they can be rather expensive depending on where you buy it and the size.

This is a picture of a real olla that's been professionally made. And following is a drawing showing you just how it works.
Inside one pot, plug the drainage hole. We used a good-sized glob of silicone and flat piece of broken tile.
Don't do this to both pots. You'll use the drainage hole in the other to fill it with water.
Squirt the silicone around the edge of one pot.
Invert the unsiliconed pot onto the siliconed pot...rim to rim.
Dig a hole in your garden near where you'll plant large enough to completely submerge your olla, leaving the open drainage hole end just above gound level. That oyster shell is to cover the opening after you've filled it with water.
