SPRING Soak the seeds in warm water of 140°F for 24h (Change the water every 12 hours) until the seeds swell. Sow the seeds at 1mm depth in the Well Drained Seed Sowing Mix at >77°F. The container with the seeds is placed in a saucer of water until germination occurs. As a result, the moisture reaches the seeds by capillary action and ensures that the seeds do not dry out. The seeds germinate in 4-12 weeks.
The average seed weight is 294,1 per gram (0,0034g).
