Cultural Tips.
Grams per 1000 Seeds: 4. Seeds per Gram: 250.
Seeding Recommendation: 10 g / 1000 plants. Sowing Rate: 2-3 seeds per cell Plug tray recommended size(s): 72, 128.
Germination: Rapidly germinating, keep seed in constant moisture (not wet) with temperatures of about +20°C. Seeds must be covered thinly. Keep in cooler conditions after germination occurs. The germination might be slower and more irregular. This poses no problems.
Scheduling.
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.
Growing On.
Container Size(s): 1-2 plugs per 11/12 cm.
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 "Magnus Superior", but an obvious place to experiment - following vernalization - would be raising daytime temperatures to 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 "Magnus Superior".
Fertilization: Medium (150-200 ppm).
