You shouldn't have to tie them at all. When they pop their heads above the screen, just gently push them back under, so they're bent over horizontal, until you're ready to let them grow vertically. The screen will hold them down, no tying needed. But if you do need to tie them down, that won't hurt anything, just don't tie them too tightly.
