If you plan to do a real ScroG I'd put the screen down as far as you can while feeding the branches thru the holes then bend the branches over and tie them to the top of the screen with short pieces of twist ties. I've done that a few times and it works fine tho best to have the screen in place when the plants are smaller so as they grow thru the screen you can bend the tips over to tie to the screen. Then as they grow you keep tying the tips down and as side branches grow out they get tied down too. Keeps the canopy nice and flat. After flipping to flower I'd tie the stretch down as well until it stopped stretching. The colas still end up a foot or more above the screen but it's better than tall branches with them on top.
