Get started by sowing the seeds in damp soil. Keep the seeds moist at all times by covering them with plastic or using a mini greenhouse. Place in a warm area with a temperature around 20-22°C and wait for your seeds to sprout. Once shoots appear, place your plants in a bright and cool area and use additional lighting during the darker months of the year. When the plants are big enough, it is time to replant them in bigger pots and place them outside. Make sure the night temperature is not below 8°C.
