And.. believe it or not, if you start trimming the tops as cuts, they'll root...

I was trying to keep a couple of Kush mothers and they got so big I just flipped them to 12/12. Honestly, they kinda sucked flowering because they were so bushy the light penetration wasn't great. They also produced smaller buds as a result..

If you do flip them, you may want to trim them up and give them a few days to recover first.
