To pre-cultivate, simply sow the seeds in damp soil compost. Cover the cultivation with plastic or use a mini greenhouse to retain moisture. Place it in a warm area with a temperature of 25°C until the seeds start to germinate. Once shoots start to appear, move the cultivation to a cooler area and preferably provide it with additional lighting. Let the plants grow big enough to be handled and transplant one plant per fertilised soil. Once the night temperature is above 8°C, the plants can be replanted outdoors.
