Make sure your seedling tray or pot (whichever you choose) has a drainage hole in it. If you choose a pot, a 5" pot should be fine. You can either use well drained soil or make a combination of 1 part each of cocopeat, vermiculite and perlite.
While sowing seeds make sure the soil is damp and not wet. Water the seeds as the soil starts to dry. It should always be moist, but never wet or muddy. Do not water the seeds if the soil is already moist to the touch, as overwatering your plant can be just as harmful as underwatering.
Keep the seedling tray in bright filtered light to begin with. Slowly introduce the plant to morning sun and bring it back in before the afternoon sun sets in. In a weeks time you can put it in direct sunlight.
