When to stop scrogging?

I have 3 of my 6 Super Silver Haze plants in a screen of green. I will switch them over to the budding phase in 2 days. How long into the budding phase does it pay to continue spreading the canopy via scrogging?

Thanks!

It depends how much they'll stretch. SSH usually stretches about twice as large during flower. You should do it 1 or 2 weeks into flower.

Sorry - never grown Super Silver Haze.
However, with scrog, you can veg until you fill the screen X%. The actual percentage will vary based on seed type. A good rule of thumb is veg til 60% full, then flip the lights to 12/12.
You can still continue to fill your screen scrog for a couple of weeks after the flip.
