About 15-17 days from sprout is bang on the money for a lot
I believe it triggers the sexing a little earlier, but do it at the right time, and the plants really take off.
Or alternatively you could leave them an extra day or so in the smaller pots to purposefully stunt the plants a little - which would be better for a true sog.
We mainly transplant as we're always needing to work with the highest number of plants possible to make selections from.
And also working with regular seeds we'll typically lose half what we start as males.
