Yes, there are many relative factors affecting dormancies, that is why I have made my own thread about it. My location being in a more thermal belt, so we get a different kind of extremes here, compared to other locations. I have to take photos year to year, season to season just to remember and understand why my plants are behaving differently.
As for the Sans, they are more of a tropical succulent so light and temps affects its growth. The temperature aspect is critical..if it gets a cold rain and exposed to temps below 50F and lower, you are for sure going to kill that plant. But let it get a warm rain or even standing in a flooded area and grown in a consistent 70F and higher temps with lots of light, it grows like weeds.
