Sowing Rate: 3 seeds per cell
Plug tray recommended size(s): 128, 288

Scheduling:
Growing On:
Best Sowing Dates: Anytime
Sowing to Germination: 2 - 3 weeks
Germination to Transplant: 4 - 6 weeks
Transplanting to Salable Plant: 6 - 8 weeks
Cutting-Back at Transplanting: Not necessary
Container Size(s): 1-2 plugs per 11/12 cm (4 1/2''); 2-3 plugs per 15 cm (6'')
Vernalization: A prudent recommendation would be to provide 6-12 weeks at an average daily temperature of 40°F (5°C). Exposure to cold may not be necessary for flowering but might improve quality.
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: Medium (150-200 ppm)
