Cultural Tips:
Grams per 1000 seeds: 7,692
Seeds per Gram: 130
Seeding Recommendation: 20 g / 1000 plants
Sowing Rate: 2-3 seeds per cell
Plug tray recommended size(s): 72s or open flats
Germination: These perennial seeds germinate very irregularly over a long period. Lower temperatures of less than +5°C [41°F] are very effective. Seed trays should not be discarded prematurely. Constant moisture must be maintained. Do not leave in direct sunlight.
For Alstroemeria we recommend to keep sowing for 3 weeks at approximately +30°C [86°F], then 3 weeks at +5°C [41°F], then at +21°C [70°F].

Scheduling:
Best Sowing Date: Anytime, but warm temperatures followed by cold temps is essential
Sowing to Germination: 4 - 8 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 (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: 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. 6-8 weeks to flower.
Fertilization: Medium (150-200 ppm)
