Germination: These seeds germinate rapidly depending on species and origin. If germination does not occur after 3-4 weeks a cooling period of 2-4 weeks is recommended.

Scheduling:
Best Sowing Dates: November - March
Sowing to Germination: 4 - 8 weeks
Germination to Transplant: 4 - 8 weeks
Transplanting to Salable Plant: 6 - 10 weeks
Cutting-Back at Transplanting: Not Necessary

Growing On:
Container Size(s): 1-2 plugs per 11/12 cm (4 1/2'')
Vernalization: Some flowering will occur the first year without vernalization, but improved flowering will occur the 2nd year; and 3-10 weeks of cool temperatures might benefit fuller flowering in the first year.
Forcing: An obvious place to experiment - following vernalization - would be raising daytime temperatures to 60° - 65°F (15° - 17°C). Provide 16 hours of continuous lighting. During the short days of winter, provide a night interruption lighting of 4 hours between 10:00 p.m. and 2:00 a.m.
Fertilization: Light (100-150 ppm)
