Germination: JELITTO GOLD NUGGET SEED® germinate after 3 - 4 weeks, keep seed in constant moisture (not wet) with temperatures of about + 20°C (68°F). Seeds must be covered thinly. After germination, the seedlings must be kept cool (+5 to 10°C) (41 to 50°F) in the months with less daylight hours, but must not be exposed to frost. At this time, it is of great benefit if the seedlings can receive at least 12 hours of light per day.

Scheduling:
Best Sowing Date: Anytime
Sowing to Germination: 3 - 4 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 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: Medium (150-200 ppm)
