I have an unused fish bowl lying around. I am keen on building a terrarium, which can include pebbles, rocks and other 'macro-stones' if you will, but not soil. I personally find soil quite icky to work with, and am a bit of a cleanliness freak. At the same time, I would like to add a water feature like a water fall and I have a pump for this. I have a lot of soil based plants at home, a lot for an apartment that size, and it can get challenging to keep on top of them. Hence, some maintenance free plants are something i look forward to.
All inputs are greatly appreciated.
