Purchase the seeds for the variety of flora you wish to grow indoors. Base your decision on the space in your home and the amount of electricity you can use. Vegetable plants require more light than many exotic plants, for instance. [2] X Research source
Research the plant you have chosen to determine the colors on the light spectrum your particular plant utilizes most. Most plants use the entire spectrum, but red and blue are the most important. Your research should tell you what color your plant craves most. For example, African violets do best under blue light, but they also need red to flower.

Pick incandescent bulbs for a superior source of red light. These bulbs are most commonly used in the home. The amount of blue light emitted from incandescent bulbs is poor, however. Select fluorescent bulbs to achieve as much as 3 times more light intensity than incandescent bulbs. There are different bulb options within the category of fluorescents. Cool white bulbs are good for plants needing blue and yellow-green light. Warm white bulbs give off more red and orange light. Full-spectrum fluorescent bulbs are the best of both worlds; they are used for many different indoor plants. Opt for high-intensity discharge lamps if you are growing a large amount of plants. They are extremely energy efficient and produce the most light out of the three types. They are also the most expensive type of bulb.
Find a location in your home to set your plants and install the lighting. Hang the bulbs the proper distance away from your specific type of plant. The distance between light and plant varies, but at least 10 inches (25. 4 cm) is a good rule. Avoid placing lights more than 40 inches (101. 6 cm) from the plant.
Give your plants a break from grow lights periodically. Plants need rest periods in order to respire. A common duration of light is between 8 to 12 hours, but some plants require more and some require less. [4] X Research source
Rotate your plants every week so each side receives the same amount of light. Change out bulbs when they begin to age. This is especially important for fluorescent bulbs, which dim at the ends over time. Water and fertilize your plants as needed.
