Have you put the seeds in the fridge with moist compost or something else?
140 days is a long time, do they come from an area that is cold for that long?
I haven't tried these so can't offer first hand advice. If they were mine I would have sown them and stood the pots outside with all the other chilling seeds. I have more success with that than with artificial chilling. I think the natural ups and downs of temperature play a part as well as the cold
