This is a simplified step-by-step photographic instructable on how to grow your own chilli peppers at home!
Chillies are extremely simple to grow at home, and don't require any fancy gardening equipment. Since a single plant can give you upto a hundred chillies, they're a perfect addition to the kitchen garden, especially since they grow really well in containers and planters!

Supplies

Materials required:

Chilli seeds
Paper towels/napkins
Planter
Soil

How to get Chilli seeds:

If you're not able to go the plant nursery and get your hands on a packet of chilli seeds, worry not! Take your favourite type of chilli pepper, slice it and remove all the seeds. Spread the seeds on a paper napkin and let them dry for 2-3 days. Once they've dried up, follow the steps below.

(Please make sure that you're always wearing gloves while handling chillies and their seeds. Avoid touching your eyes, face and any sensitive skin, and always wash your hands afterwards.)

Step 1: Prep the Seeds

Spread open a paper towel, place all chilli seeds evenly on it. Then spray some water on them and fold the paper towel close. Now keep this aside for about a week while making sure that the paper towel is regularly sprayed with water to keep it moist and damp. Keep it in a warm and humid place.

Alternatively, you can skip this entire step. First, wet the seeds nicely and sow them in soil at a depth of about 2-3 cms. The chilli seeds will germinate in about 1 week. Water them every alternate day, keep the soil moist and make sure they are not exposed to harsh winds or strong sun.

Step 2: Soil and Germination

Chilli plants usually require an airy soil which is well drained. Add a little bit of compost to it and give it a good mix. Keep the soil moist but don't overwater it. Water every alternate day or every 2 days depending on the weather. Make sure there is a wet-dry-wet-dry cycle of watering.

The seeds will germinate and you'll see two small leaves on the surface of the soil within 7-10 days of planting the seeds.
Keep watering them every alternate day and make sure they're exposed to 4-6 hours of sunlight daily.

Step 3: Flowering

Once the plant is about 8-10 inches in height, it'll bring out small buds which will blossom into cute little white flowers about 1-1.5 months after planting them.
The flowers will remain on the plant for about 7-10 days, then fall off. Then you'll see a cute little baby chilli growing in it's place.

Step 4:

Regularly water and nourish the plant and the chillies will grow bigger and bigger. The bigger they are the more potent their spiciness is.
Once the chill is about 5-7 cms long you can pluck it to cook with it. However, If you want it to be spicier you can leave it on the plant itself. If you leave them long enough on the plant, the green chilli peppers will eventually turn red. The redder it gets, the hotter it the chilli is!
