When to swap to 12/12 with a SCROG

[steppedinds]

When exactly should you swap to 12/12 when using a SCROG? Should you wait until the entire screen is full? 3/4 full? My previous SCROG grows have been autos, so I have a 2 week unsurity period comparing to past grows. I'm thinking 2 more weeks on these girls, maybe a few more days depending on what it looks like at that point.
Thanks in advance

You can control a scrogged plant quite easily, so even a screen that's overfull can work just fine. Mine are usually past full when I flip. More commonly people flip at around 3/4 full. Yes probably a couple more weeks.

Depending on your light and space, which yours looks to be good based on your signature, I would probably fill the screen and then allow for 6" of vertical growth. Make sure that the bud sites are evenly spaced. Less can be more since they can grow fatter without competition. Account for the bushing out that each vertical shoot will have. Good luck and I wish you a bountiful harvest.
