How to Grow
3500 seed/gram. Start seeds indoors in a soil-less mix about 8 weeks before planting out. Sow seed 3 mm (1/8″) deep and provide bottom heat to keep the mix at a temperature of 24 C (75 F) for the 8-12 day germination period. Grow on under lights at a slightly cooler temperature of 18-20 C (65-70 F). After hardening off, plant out in late May spacing the plants 25 cm (10″) apart.
