Growing Peppers Indoors – Guidelines & Tips

Growing peppers indoors can be a challenging, yet rewarding experience. When done correctly, gardeners can enjoy vibrant, flavorful peppers year-round and gain the satisfaction of producing them without relying on external sources. Here are some guidelines and tips to help you get started.

Choose a Plant Variety

The first step in growing peppers indoors is to select a variety that will thrive indoors. Choose a compact pepper variety that is meant for containers, such as Cumari pepper, Anaheim chili pepper, or Hungarian sweet peppers. Sweet bell peppers are also popular options, as they tend to have shorter growth cycles and require less maintenance than some other peppers.

Choose Containers

While you can use traditional planters for growing peppers indoors, there is a wide range of other containers that can work better. For example, you can upcycle plastic containers to grow peppers easily and efficiently. Opt for containers that feature a large drainage hole in the bottom to prevent rot and enable adequate airflow. Additionally, use containers that are at least 8-10 inches in diameter to ensure proper growth.

Select Light

Peppers need plenty of light to thrive, so make sure to provide your pepper plants with at least 8-10 hours of light per day. If you don’t have access to natural sunlight, choose LED grow lights to supplement the light your plants need. Position the lights about 12-18 inches above your peppers and adjust them as your plants grow. Additionally, use supplemental sources like reflective walls or aluminum foil to direct more light to the plants.

Ensure Proper Temperature

To facilitate proper growth, peppers require temperatures between 60-85F. To ensure your plants will be comfortable in their indoor environment, invest in a digital thermometer. This will allow you to monitor and adjust the temperature as needed.

Add Nutrients

Peppers, like any other plant, need proper nutrition to grow optimally. To ensure your peppers get the proper nutrients, use an organic liquid fertilizer once or twice a month. Additionally, to promote healthy growth and vibrant colors, use granular fertilizer every four to six weeks.

Be Mindful of Pests

Pests are always a threat when growing peppers indoors and can be difficult to eliminate. To protect your plants from pests, invest in a pesticide that is specifically designed for indoor plants. It is also recommended to spray your peppers with a diluted solution of neem oil, if available. This will form a protective barrier on your plants and deter pests.


Growing peppers indoors can be extremely rewarding, but it can be tricky to find the right balance. By following the guidelines and tips provided above, you can increase your chances of success and enjoy the flavor of fresh peppers all year round.
