I have some ideas on pot design for subsurface irrigation and concrete is easy and cheap to prototype with. I'm aware concrete is porous and might need to be sealed. Just how wasteful are such pots? It's only the base that will be concrete whilst the upper part exposed to the air will be an off the shelf plant pot.
I'd rather lose a bit of water than double the complexity by sealing the concrete. After prototyping I'd be more willing to seal or perhaps avoid concrete altogether.
