Long Day-Short Day Critical daylength is about 14 hrs. The fastest flower initiation is at a daylength of a minimum of 16 hrs. (or night interruption). This is approximately 3 weeks shorter than 14 hrs. provides. After flower bud initiation, a shorter daylength of 13 hrs. or less will significantly reduce time to colour the flower buds. The fastest flower timing occurs under a long day and short day combination, i.e., 5-6 weeks of 16 hrs. or longer daylength (long day) for flower initiation followed by 4 to 5 weeks of 13 hrs. or shorter day (short day) for flower development (pink colouration).
