Growing Peppers Indoors – Guidelines & Tips

Growing peppers indoors has many advantages for both the amateur and experienced gardener. Peppers grown indoors are less vulnerable to disease and pests, and produce a greater yield on a consistent basis. Growing peppers indoors is relatively easy but there are a few guidelines and tips that should be followed to ensure success.


Peppers need plenty of sunlight to survive and thrive indoors. A minimum of 6 hours of sunlight is recommended for peppers grown indoors. An ideal spot for pepper plants is a south-facing window facing sunlight for at least 6 hours each day. If you do not have access to a window, then you can use grow lights to ensure the pepper plants receive adequate light.

Temperature and Humidity

It is important to monitor the temperature and humidity of the growing environment. Peppers prefer temperatures in the range of 70 to 80 degrees Fahrenheit. Too much heat or too cold of temperatures will have a negative impact on the pepper plants. Humidity should also be in the range of 50 to 60%. To maintain temperatures and humidity levels, consider using an indoor thermometer and hygrometer.

Soil and Fertilizer

Soil is an important factor when growing peppers indoors. Peppers like a neutral pH soil that is mostly made up of peat moss and sand. Be sure to add fertilizer to the soil to ensure the pepper plants are getting the right nutrients. Consider using a water-soluble fertilizer that can easily be applied every 2 weeks.


Water is essential when growing peppers indoors. Peppers need a consistent amount of water to stay healthy and produce high yields. Water your pepper plants when the soil is dry to the touch and be sure to not over-water the plants. If the soil is too wet, the roots of the pepper plants can rot and lead to disease.

Pests and Disease

One of the main benefits of growing peppers indoors is the decreased risk of pests and disease. Make sure the growing environment is clean and free of debris to reduce pests. Monitor your plants carefully and check for any signs of disease or pests. If there is an issue, contact a local garden expert.


Harvesting the peppers is the most rewarding part of the growing process. Peppers can be harvested as soon as they reach a good size and color. Use pruning shears to carefully cut the peppers off from the stem. Make sure you leave enough stem attached to each pepper to ensure the remaining peppers on the plant continue to grow and produce.


Growing peppers indoors can increase your chances of success and yield higher harvests on a consistent basis. Follow the tips and guidelines above to ensure your pepper plants thrive and produce the highest quality peppers.
