Growing Peppers Indoors – Guidelines & Tips

Growing peppers indoors is becoming increasingly popular as people look for ways to grow their own food year-round in a controlled environment. Peppers are easy to grow indoors and can be harvested right in your own home. Below are some guidelines and tips to get you started with growing peppers indoors.

Climate Control

Growing peppers indoors requires controlling the climate to create an environment that is conducive to growing the peppers. Temperature, humidity, and light are all factors that need to be controlled. Temperature should be kept between 70-85°F (21-29°C) with lower temperatures being better for slower growth and more flavor. Humidity levels should be kept between 50-70% for optimal growth, and it’s important to keep an eye out for any signs of fungus or pests.


Providing enough light is the biggest challenge of growing peppers indoors. Peppers require a lot of light to thrive, and in most cases you will need to supplement the light they receive with Grow Lights or LED Lights. Be sure to read the instructions that come with your lights to get the right spectrum of light for optimum plant growth. It is best to provide 12-14 hours of bright light per day for pepper plants.

Soil & Fertilizer

It is important to use quality, well-draining soil for best results. Peppers prefer a soil with a pH of 6.0-6.5. Adding slow-release fertilizer at the time of planting, followed by regular additions of liquid fertilizer throughout the growing season is advised. Peppers prefer a nutrient solution that includes nitrogen (N), phosphorus (P) and potassium (K)


It is important to not let the soil dry out, or the peppers will not grow. In order to keep the soil consistently moist, consider setting up a drip or wicking system that can be regulated to provide the right amount of water. Check the soil regularly and feel the texture to determine when to water, and ensure any water run-off is drained away properly.


Peppers can take up to five months to mature from seed to harvest. When the pepper is bright and firm, it is ready to be picked. Be sure to pick regularly in order to encourage the plant to produce more peppers. In general, it is best to wait until the peppers are fully mature before harvesting.


Growing peppers indoors is an enjoyable and productive activity that can provide you with tasty fruits throughout the year. Get started today by following these guidelines and tips for growing peppers indoors and you will soon see the delicious results!
