Growing Herbs Indoors Without Sunlight

It is well-known that most plants require sunlight to grow. A particular amount of sunlight is needed for the photosynthesis process to occur. Photosynthesis helps plants create chlorophyll, a green pigment in a plant that gives it food.

Many herbs can be grown in pots and placed indoors. The perfect area for your potted herbs is generally in a room facing south that gets direct sunlight. However, it is also possible to have home-grown herbs, even without a room that receives direct sunlight.

A grow light is a unique type of electric light that is specifically designed to give natural light when growing plants indoors. In some conditions, it can also be used as a supplement for natural light if there is no natural light available.

What Type of Grow Light is Best for Herbs Indoors?

Light is the most crucial component of your indoor growing system. If you want regular harvests, it must be sufficient and intense. The type of light you use is not only crucial for your herbs’ survival, but it also determines how fast and sturdy your herbs will grow.

Improvements in spectral display and fluorescents’ intensity explicitly designed for indoor gardening, like high output T5 lamps, make them a good option for regular gardeners.

Essential Tips for a Successful Indoor Herb Garden

Herbs are easy to grow indoors, provided you make the right start. The key to creating a thriving indoor herb garden is understanding the plant’s requirements and ensuring you give them what they require.


Herbs growing indoors require at least 6 hours of sunlight to thrive. When they don’t get sufficient sunlight, they will become stringy and eventually lose their flavor. Keep your herb garden in the sunniest area you can get if you feel that the site may not offer sufficient light. Substitute with a fluorescent bulb and keep it less than a foot (30 cm) from the herbs.

You might be required to rotate the pot that the herb is growing in so that all the herbs get equal amounts of sun and ensure they don’t grow crooked.

Most herbs do not withstand cold temperatures. The herbs will grow well indoors if the temperature around them is 65-70 degrees F.

Ensure your herb garden is not affected by drafts from doors and windows. Even a little amount of cold can destroy your herbs.


Indoor herbs gardens need regular watering. Ensure you don’t allow them to dry out, but ensure you are not overwatering them. Inspect your indoor herb garden every day and water it when the topsoil starts to feel dry. You can also add some water-soluble fertilizer to the water to help the herbs have the nutrients they require.


Indoor herbs require high humidity and proper air circulation. Steam your herbs once a week and place them on a tray of pebbles filled with water to maintain the humidity. When you find your herbs are affected by mildew, you may need to consider adding a fan to maintain consistent air circulation.


Even if all plants require a certain amount of natural light to thrive, growing herbs indoors without sunlight is possible, as long as all other conditions are kept right. There are ways to make up for the lack of direct sunlight. The perfect way to supplement natural light is by using grow lights to compensate for natural light and help your plant grow in indoor conditions.
