Sowing instructions
SPRING Soak in 0.2% Potassium nitrate KNO3, just covering the seeds, for 30 min then wash thoroughly in running tap water. Sow the seeds at 5mm depth in the Well Drained Seed Sowing Mix at >77°F. During germination keep the substrate moist and protected from direct sunlight. The seeds germinate in 2-6 weeks.
