How to Grow Herbs Indoors Under Lights


Although there are several hydroponic kits designed and marketed for growing indoor herb gardens, you don't have to be a scientific genius, or even a hydroponic gardener, to grow herbs indoors in containers. Herbs are garden plants that adapt well to low-light conditions. Because of this, herbs can be grown indoors in small indoor container gardens. A kitchen herb garden in containers is a good way to grow herbs year-round.

Step 1

Select containers that are appropriately-sized for your herb garden. Containers should be at least 4 inches in diameter. Woody, shrub-like herbs such as rosemary and lavender should be planted in larger pots, such as 12-inch-diameter containers.

Step 2

Use a soilless potting mix in the containers. Soil contains microbes and nematodes that will attack the roots of plants in containers.

Step 3

Place herbs in containers in a sunny, south-facing windowsill.

Step 4

Supplement herb light requirements with fluorescent lighting from lamps placed 6 inches above the herbs. Most herbs require 6 hours of direct sunlight daily. If herbs do not receive this, they will become spindly.

Step 5

Check your herbs daily and water as needed. The soil in herbal containers should remain as damp as a wrung-out sponge.

Step 6

Fertilize with a liquid, balanced (10-10-10) fertilizer added to the watering can along with water. Use fertilizer according to the package directions. Fertilizer directions vary according to the fertilizer brand.
