...after 10 grows of the same hindu kush, my friend finally perfected his process by
increasing the dark period by a half hour every two to three days to 10 light/ 14 dark
when finishing.
He seemed to firmly believe the increased dark induced the buds to FINISH NOW!!!
And harden up.
as far as from veg to flower, I hear reports of less stretching by this same method,
to change the period over a week instead of immediately.If you have time, or issues
with growth control, you might want to experiment with it. My current crop of Dabney
Blue and REZ Sour D seemed to stretch when I flipped, now 2 weeks in and are trained
rather nice, but I have a few feet of play vertically.
Hope this anecdote helps....love is my best fertilizer.
