To plant ghost chili peppers, first choose a sunny location with well-draining soil. Start by preparing the soil by adding compost or fertilizer. Sow the seeds 1/2 inch deep and 2-3 inches apart, then water well. Keep the soil moist and warm (70-80°F) until the seeds germinate in about 10-14 days. Once seedlings have emerged, thin them to 18-24 inches apart. Water regularly, but avoid overwatering. Ghost chili peppers take about 100-120 days to mature, and they prefer warm temperatures. Enjoy the fiery fruits of your labor!
