Cultural Tips: Scheduling:
Growing On:
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: These are very tiny seeds which should be mixed with finest sand or talcum for an even sowing. Do not cover with compost, only press them in gently. Irrigate from the bottom or with a hand-sprayer, so that the seeds will not be washed away.
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.
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 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)
