To decrease the germination time even further you can also first germinate the seeds in a bottle before sowing them. To sow the seeds make approximately 1/2 inch depressions in the soil, place the seeds on their side and cover them up with loose soil. Water gently so that the soil is not disturbed to expose the seed. Keep the soil moist all the time. You can plant 4-5 seeds in a 15 liter pot.
