Soak the seeds during 48 hours in water. Sow indoors from mid January till
mid October at 25º C, in a seedtray. Keep soil moist by spraying water with
a plant spray and cover the tray with cling film to prevent the soil from drying
out. Remove the cling film when the first shoots appear. As soon as the
height of the plants is 5-6 cm, you need to transplant them into flower pots.
