Cultural Tips:
Grams per 1000 seeds: 0,2
Seeds per Gram: 5000
Seeding Recommendation: 0,5 g / 1000 plants
Sowing Rate: 2-3 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: 6 - 8 weeks
Transplanting to Salable Plant: 8 - 10 weeks
Cutting-Back at Transplanting: Cut back 1-2 times; once at transplanting; once again 4 weeks later to keep more compact

Growing On:
Container Size(s): 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: Early spring flowering. No forcing necessary.
Fertilization: Medium (150-200 ppm)
