Nah man, I've had great successes with the 12/12 from seed method.
Some have even gotten the holy grail of 1g/watt.
Sexing in as little as 20 days avg.
The stresses from a shortened light cycle are so minimal as to be negligible or nonexistent.
Mid wager to say that LST brings more of a stress.
Plants grown under this lighting schedule have no basis of comparison to another light cycle.
Therefore, it's all it's ever known, and
all plants adapt to their particular circumstances.
Some say that it decreases yields. I can see where they would say that.
You DO get less bid from a plant grown this way. (larger plants, larger yeilds)
BUT, the bud to plant RATIO goes significantly higher in a 12/12 FS. (less stem, trim, etc.)
But as I always say, it takes all kinds in our world..
We do what we do. And that's good enough for me
