This is what you need:
1) A bright south facing window or a bulb with about 4000K-6500K rating.
2) Some basil seeds, a plant pot and soil from your local store.
Step 1: Germinating
Take some seeds and put them onto the soil. Spacing from seed to seed should be about 2 cm (1 inch). Don't cover them with any soil, as basil seeds need light to germinate.
Cover the pot with a piece of glass or some plastic wrap to keep the soil moist.
Then put the pot to an bright warm place. About 20-25°C should be fine.
After some time the seeds will turn slightly blue. Don't be shocked. That's absolutely normal.
A few days later your seeds hopefully germinated.
