Growing Peppers Indoors – Guidelines & Tips

Growing your own peppers indoors is a great way to enjoy the flavors of the season year-round. Although peppers are usually considered an outdoor crop, they can be successfully grown indoors in pots, with the proper care and conditions. Here are some guidelines and tips for growing peppers indoors.

Container Choice & Drainage

When choosing a container for your peppers, opt for one that is at least 12 inches (30 cm) in diameter, with plenty of drainage holes at the bottom. Be sure that the container is made of breathable material such as ceramic, plastic or terracotta.

Soil Requirements

Peppers need soil with a slightly acidic pH, so be sure to use a potting mix designed for peppers or tomatoes. Peppers prefer a soil with good drainage and nutrients, so a mix with compost or manure added is best.

Temperature & Humidity

Peppers prefer a temperature range of 70-90°F (21-32°C). To keep the air in your planting area moist and prevent drying out, you can use a humidifier or place a shallow tray of water nearby.

Fertilizer & Watering

Fertilize your pepper plants every two weeks with a general-purpose fertilizer and water them regularly, ensuring that they are moist but not soggy. Peppers should be given one inch of water per week, either by hand or through an automated system.

Light Requirements

Peppers need at least 6 hours of full sun per day. You can provide this through either natural or artificial light sources. If using artificial lights, aim for a full spectrum with a 6500-7000 Kelvin (K) rating.


When flowering, peppers need to be pollinated in order to set fruit. You can help pollinate your peppers by hand or using a small artist paint brush that has been dipped in water.


Peppers are ready to harvest when their fruits are full size and bright in color. Take care to not over-pick, as peppers can quickly become over-ripe and lose flavor.

With the proper care and conditions, you can easily grow peppers indoors all year round. With a little knowledge and a few simple tips, you can enjoy the flavors of the season right from your own home.
