I have been told to use round containers, because the tubors will follow the
curved walls and grow. I have also been told that rectangular containers
will stop the tubors from spreading, as they will hit the corners and stop.

Yeah, but, than they died.

I am starting to think, a bunch of long rectangular containers are the way
to go. It sounds like you would have a lot of control, and the roots would
not be so tangled. Any thoughts?

So I don't think this would work. ~ jan
