Growing Peppers Indoors – Guidelines & Tips

Growing peppers indoors can be a great way to get your hands on some tasty, homegrown produce year-round. If you’re an aspiring green thumb who’s looking to add a bit of spice to their culinary repertoire, growing peppers indoors is a great place to start.

Peppers are relatively easy to grow, so chances are high that you’ll have success with them if you’ve got a basic understanding of gardening and how to create the best environment for your plants. Here’s your guide to growing peppers indoors, complete with tips and guidelines to ensure that you get the best results.

Choosing Your Varieties

The first step when it comes to growing peppers indoors is to choose your variety. Sweet peppers, such as bell peppers, are a good option since they are relatively easy to cultivate inside. Hot peppers, such as jalapeno or habanero, are slightly more difficult but yield an abundant harvest.

Before selecting a variety, ensure that you have ample space for your plants to grow. Consider the height of mature plants and the spread of their leaves to ensure that your chosen variety has enough space to grow in your chosen environment.

Potting Soil & Containers

Your peppers will need adequate soil in order to thrive. Choose a quality, well-draining container mix that is high in organic matter and use a pot or container that is at least 6-inches in diameter.

Be sure to use a pot with adequate drainage holes to ensure that the water is able to escape from the soil and that your plants don’t get waterlogged.

Light & Temperature

Another essential factor in pepper growth is light – peppers need a minimum of six hours of light each day. If growing indoors, you must ensure that your plants receive adequate light, either from a grow light or a sunny windowsill.

When it comes to temperature, peppers prefer temperatures between 65°F and 85°F (18°C to 30°C). In cooler climates, a heater may be necessary to keep the temperature adequately warm for your plants.

Fertilizing & Watering

To encourage your pepper plants to produce a generous crop of fruit, fertilize your plants once a week with a liquid fertilizer. Be sure to water your plants regularly, but err on the side of under-watering rather than the other way around. Don’t water your plants to the point where the soil is soggy, as this could cause root rot or other issues.

Pests & Diseases

Keeping an eye out for pests and diseases is key to avoiding damage to your pepper plants. Common pepper pests include aphids, whiteflies, and spider mites. The best way to combat these pests is to clean up the area, remove their sources of food, and introduce natural predators like ladybugs or Lacewings.

If you see any signs of disease or discoloration, be sure to remove the plant immediately, as diseases can quickly spread and cause harm to your other plants.


When you notice peppers forming on your plants, they will be ready for harvesting in about two months. Be sure to wait until the peppers have completely turned red – or whatever color your variety usually turns when ripe – before harvesting, as this will guarantee the ripest and sweetest flavor.


Growing peppers indoors can be a great way to enjoy homegrown produce year-round. Just remember that you need to supply your plants with the right kind of soil, light, temperature, and water in order for them to thrive. If pests or diseases creep their way in, be sure to take action quickly to protect your plants. With these guidelines and tips in mind, you should have no problem growing peppers indoors. Have fun and happy harvesting!
