Within 10 days you will notice new seedlings coming out of the seeds. At this time you can remove the plastic covering and place the container in the region where it can receive direct sunlight.
Once your seedlings reach 4 to 5 leaf stage then you can transplant them in the growing pots. Fill the pots with growing potting and make sure that the drainage holes doesn’t get blocked.
With the help of garden tool like trovel, dig a small hole in the centre of the pot enough to have roots of the seedings in them. Carefully take out seedlings from the germination container and plant them in the growing pot.
Water gently in the pot after transplanting and place the pot in semi shade for 5 days so that transplanted plant gets well established in the pot. After 5 days place the pot under direct sunlight.
