The container was my wife's idea, and I told her I didn't like it (even prior to SF disapproval!). She actually agreed, she had just been putting it there for lack of another spot in the moment. As for the placement, I am concerned about the red one as well. But we'll see. The red one in particular is not meant to get very large. The green one my big regret is not having been able to elevate it a bit more. Good advice all around though and I do at least partially agree.
