Cultural Tips:
Grams per 1000 seeds: 11,111
Seeds per Gram: 90
Seeding Recommendation: 75g / 1000 plants
Sowing Rate: 6 seeds per cell
Plug tray recommended size(s): 72s or open flats
Germination: Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about + 20°C (68°F). Keep in cooler conditions after germination occurs.

Scheduling:
Best Sowing Date: Anytime
Sowing to Germination: 2 - 3 weeks
Germination to Transplant: 4 - 8 weeks
Transplanting to salable Plant: 6 - 8 weeks
Cutting-Back at Transplanting: Not necessary

Growing On:
Container Size(s): 1-2 plugs per 11/12 cm (4 1/2''); 2-3 plugs per 15 cm (6'')
Vernalization: Some flowering will occur the first year without vernalization, but improved flowering will occur the 2nd year; and 3-10 weeks of cool temperatures might benefit fuller flowering in the first year.
Forcing: There has been no research on 'Arctic Glow', but 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. Some later flowering species can be forced in 14 - 16 weeks and perhaps sooner at warmer temperatures. Further experiments are warranted with 'Arctic Glow'.
Fertilization: Medium (150-200 ppm)
