8500-10000 seeds/gram. Start seed indoors in a soil-less mix 6-8 weeks before planting out time. Since the seed is so small, leave it uncovered on the surface of the growing medium. Pelleted seed must be lightly misted after sowing until the seed coating dissolves completely or germination may not occur at all. Apply bottom heat to keep the growing medium temperature at 25 C (77 F) for the 14 day germination period. After germination, grow on under lights at a cooler temperature of 15 C (60 F) until hardening off and planting out to a sunny spot in late May. Space plants 20 cm (8") apart in the garden.
At 25 C (77 F) about 2 weeks - a cooler growing medium temperature will increase germination time
