Idea for a setup

[rbarata]

Rings any bell to you?



And this one?



A little bigger...



Instead of a closed/semi closed terrarium why not construct a wall of some non degradable material, maybe with some terraces, install a small pump to get water from a small container and, by means of a piping, make it fall by that wall. Install some suitable plants on the terraces and, ideally, one just need to refill the container...

Just an idea that came to mind when I remembered these small fountaing used for decoration.
