I have a lovely east facing spot for an interesting habitat!
I would really like to build some sort of a self-watering dripping wall...similar to what's seen here: http://www.pinguicula.org/pages/culture/JSteiger.htm
However, my wall would be dedicated to mexican pinguicula, probably p. gigantae since they may do well while receiving morning sun in San Diego.
I have done something similar, but with native succulents:
The plan would look more like this wall found at the Huntington, however, than the wall linked above:
The wall will be hanging from the roof and removable, ideally. It needs to be light. I have a power outlet close by for running the pump.
I am very interested in learning whether any of you have attempted to do something like this, of what materials I should make the wall out of...particularly what material could I use to construct the wall (fiber?) as a replacement soil for p. gigantea. How about a sandwich with a layer of soil between a back and a netted front?
I have a few ideas but wouldn't know where to start.
Many thanks in advance.
