The hormones responsible for flower are degraded by light. 12 hours of darkness allows the flowering hormones to build up to a concentration needed to induce flowering. I think that the 36 hours of darkness is more people going 12 hours is good 36 must be better. I have not seen any evidence that once you hit the threshold of need hormone that more of it causes faster switch to flower. Personally I have had great results with 12 and have never tried 36 hours of darkness. I would guess that you would see less stretch more to the fact that they got less light. If you want to slow stretch increase you potassium to nitrogen levels. That is why a lot of bloom formulas are really high in potassium. Well that is my two cents on the topic.
