I don't think there is a standard way of doing it as far as inside/ outside, leaving one side open, etc. Too many variables in everyones space and setup. My space is really small, so I have the screen on the walls and tie the plants back. I wouldn't be able to reach the back if the plants were outside the screen. So it really all depends on your space, how big the plants are going to be, etc. You basically want to be able to reach anywhere on the screen. If you can't do that, figure out a way to make it so you can.
