Hi.
I have experimented with bending the cola branches, with success. I bent them a little bit but from 2-4 places like 5-10 cm apart. You can see it in my diary
in action. Those branches did not slow at all, and are producing fatter buds than those around.
You can scroll through the pics if you feel like it. The bent are in the middle of the screen.

Be gentle, soften the tissue first with wiggling it abit between your fingers, then bend.
Bending during flowering is a no no for many, I found an ok for it from a high times pro tips-list. So I tried it, it works.
