Seed germination temperature 18-20 °C, 3-7 days emergence, and then need to be about 8-10 weeks at 18 °C vegetative growth, that is, 8 weeks for large flower species, 9-10 weeks for multiple flower species ( All from the day of the first transplant.) Then flower buds were differentiated at 9-12°C for 6 weeks and then flowering at 9°C for 9 weeks at 13°C.
