Sowing instructions
SPRING Soak the seeds in ambient water for 48h (Change the water every 12 hours) until the seeds swell. Keep in refrigerator at 39°F for 3 weeks in humid substrat. Sow the seeds at 2mm depth in the Well Drained Seed Sowing Mix between 50-59°F. Germination takes place in the dark. The seeds germinate in 2-3 weeks.
The average seed weight is 1000,0 per gram (0,001g).
