Stush, Full sun is what I grow it in and it barely had any soil. It is mostly aquarium gravel. The enormous amount of gravel is because I have it growing with cactus and I tend to kill them.
The only way I can avoid killing cactus in my house is to only use 2 tablespoons soil and the rest gravel. I had two very large fish tanks that I no longer use so I have been using the gravel in my succulent plant pots.
