Growing Peppers Indoors – Guidelines & Tips

Indoor gardening is becoming increasingly popular, with many home gardeners enjoying the challenge of cultivating their own vegetables and herbs, even in the smallest of spaces. At the top of the list for many gardeners is growing peppers indoors, providing a bounty of flavor with little effort.

For anyone wanting to start growing peppers indoors, here are a few guidelines and tips to get you started:

Choose the Right Variety

When growing peppers indoors, it’s important to select varieties designed to thrive in this environment. Varieties such as bell peppers, jalapeños, serranos, and habaneros are some of the more popular options, all growing well indoors. Peppers generally require a minimum of six hours of light per day, so if natural light is limited, invest in a quality grow light setup.

Optimal Growing Conditions

Peppers thrive in warm temperatures of 75-85°F, dropping into the low 70s at night, so ensure the room where your peppers are growing is kept warm during the day. Once the peppers are in place, also check that the soil temperature is in the optimal range, area generally 68-80°F.

Humidity levels should be kept between 50-70%, so consider using a humidifier to keep everything at the right level. Keeping the soil damp is also important, as peppers prefer to stay consistently moist. Moisture levels can be monitored with a moisture meter.

Fertilizing & Pruning

Peppers need regular fertilization to stay healthy and productive. Choose a nutrient-rich fertilizer that is low in nitrogen and high in phosphorus and potassium, designed for pepper and other vegetables.

Lastly, pruning is important to keep the plants healthy, preventing them from becoming overcrowded and spindly. Prune the plants by pinching off the top of the pepper flower buds, along with any discolored leaves, to improve air circulation and maintain healthy, productive plants.


Growing peppers indoors can be an enjoyable experience for anyone who loves the taste of freshly-picked peppers. With the right environment and adequate growing conditions, any home gardener can enjoy the rewards of a productive pepper harvest.
