Cultural Tips:
Grams per 1000 seeds: 0,067
Seeds per Gram: 15000
Seeding Recommendation: 1 g / 1000 plants
Sowing Rate: 8 seeds per cell
Plug tray recommended size(s): 128 or 288
Germination: Rapidly germinating (2 to 3 weeks), keep seed in constant moisture (not wet) with temperatures of about + 20°C (68°F). Do not cover the seeds, but tightly press into the earth. Keep in cooler conditions after germination occurs.
Scheduling:
Growing On:
Best Sowing Dates: Anytime
Sowing to Germination: 2 - 3 weeks
Germination to Transplant: 4 - 8 weeks
Transplanting to Salable Plant: 6 - 10 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)
