Grow Lights for Indoor Plants – Getting Started

With a set of grow lights, you can grow many plants indoors, including houseplants, orchids, and even some fruit and vegetable crops. Grow lights are ideal for seed starting because they help ensure stocky, green seedlings. A wintertime harvest of herbs and salad greens can also be grown under lights. By learning how plants use light and about the fixture options, you can select an indoor grow lights system that is right for the plants you want to grow.

Sunlight contains the complete spectrum of light including all colors of the rainbow: red through yellow to blue and violet. Like plants growing outdoors in the sunlight, indoor plants grow best under full-spectrum bulbs, which produce a balance of cool and warm light that replicates the natural solar spectrum. They're excellent for seedlings as well as houseplants, culinary herbs and other plants. All of our grow light fixtures, stands and replacement bulbs are full-spectrum.

No matter what types of plants you are growing, you must give them a rest. When it's dark, plants respirate, which is an important part of their growth process. The balance of rest time to active growth time affects many biological processes, including the growth rate, and the setting of buds and fruit.

Vegetable seedlings growing under full-spectrum lights

Vegetable seedlings need 14-18 hours of light a day.

Botanists usually divide plants into three categories relating to their preferred day length: short-day, long-day or day-neutral.

Short-day plants, such as chrysanthemums, kalanchoe, azaleas and begonias, will thrive on less than 12 hours of light per day. In fact, these plants must usually go through a series of even shorter days before they will set buds and flower.

Long-day plants require 14 to 18 hours of light each day. Most seedlings for vegetables and garden flowers are long-day plants. When they don't receive enough light they get pale and leggy.

Day-neutral plants, including foliage plants, geraniums, coleus and African violets, are usually satisfied with 8 to 12 hours of light all year-round.
