Growing Peppers Indoors – Guidelines & Tips


Growing peppers indoors has many advantages, such as easy access to the plant and year-round access to fresh peppers. You can start with seeds, buy pepper plants, or purchase a young pepper plant from a nursery. Here are some tips and guidelines on how to successfully grow peppers indoors.

Grow Lights for Peppers

Peppers are very sensitive to light, and need around 6-8 hours of bright sunlight daily. If you don’t have enough natural sunlight for your peppers, it is recommended to use grow lights to provide them with the right amount. Choose LED or fluorescent bulbs in the 4,000 to 6,500K range for maximum pepper growth.

Soil and Pot Choices

Choose a good-quality potting mix that has some added organic matter. Try to choose a pot that is wider than it is deep because peppers have a shallow root system. For best results, use at least a 10-inch pot.

Watering and Feeding

Avoid over-watering, as this can lead to root-rot and insufficient drainage can cause stunted plant growth. Water your peppers when the top inch to two inches of soil is dry. Pepper plants need regular feeding with a liquid fertilizer every two to four weeks, as they will respond well to added nutrients.

Temperature and Humidity

Peppers are sensitive to both temperature and humidity. During the day, peppers need uniformly warm temperatures of 70-90°F (21-32°C). At night, temperatures should drop to 65-75°F (18-24°C). Most peppers will also grow better in high humidity. To increase humidity around your peppers, mist the plants two to three times a day or place a humidifier in the same room.

Pests and Diseases

Pests such as aphids, spider mites, and whiteflies can attack pepper plants. If spotted, spray your plant with an organic insecticide. Diseases such as blight, mosaic virus, and root rot can also affect peppers. Prevention is the best defense, so make sure to keep your plants away from overly wet conditions. If you spot any signs of disease on your pepper plants, take immediate action and reduce watering as soon as possible.


Growing peppers indoors can be a rewarding experience. With the right lighting, soil, water, temperature, and humidity, you can achieve a successful pepper harvest. Just remember to keep an eye out for pests and diseases, and take preventive measures to keep your plants healthy.
