My preference is to put it outside. I live in a mediterranean climate, with winters in the mid-30's (F), with the occasional night or two of below freezing. Summers are typically in the 90's (F) with 100-105F not being unheard of. Lots of rain in the winter, typically, sometimes (rarely) snow. Hot and dry in the summer, cold and wet in the winter. I live in a house, so it can sit in morning sun or all-day sun, depending on where I decide to place it.
Inside, the only issue I have with the planter is it is big and would take up a lot of real estate, so it would probably not be allowed to live in the garden window, where the sunlight is the best for plants. I would have to either establish artificial lighting over it (something I don't really want to do) or put in plants that don't mind filtered light.
Right now, I am leaning toward VFT's or Drosera. What would you plant?
