Actually, a simple method of attaching the screen to the pot itself is to use clothes hangars for the screen support, and attach them to the outside of the pot with duct tape or bungie cords. This keeps the screen and pot as one unit. This does mean you need one smaller screen per pot, as opposed to one large screen for every plant, but the advantages are obvious. There is very little, if any, downside to ScroG if you do it this way.
