Cultural Tips:
Grams per 1000 seeds: 0,05
Seeds per Gram: 20000
Seeding Recommendation: 0,25 g / 1000 plants
Sowing Rate: 5 seeds per cell
Plug tray recommended size(s): 128 or 288
Germination: Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C [68°F]. Do not cover the seed but tightly press into the earth. Keep in cooler conditions after germination occurs.

Scheduling:
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

Growing On:
Container Size(s): 1 plug per 8/9 cm (3 1/2''); 1-2 plugs per 11/12 cm (4 1/2'')
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: Light (100-150 ppm)
