Produce
Grow lights work great for people who want to grow their own fresh produce but don't have access to a land, including individuals who live in apartment buildings or elderly people who can no longer physically keep up caring for a garden. Plant tomatoes, hot peppers, peas, lettuce, wheatgrass or strawberry seedlings in pots and place them under a grow light. Grow lights also allow you to grow some seasonal produce year round and help cut down your grocery bill.
Herbs
If you love to cook using fresh herbs but don't have a window sill in your kitchen to cultivate herb plants, invest in a grow light. Grow different types of basil, sage thyme, rosemary or chives on your kitchen countertop using a grow light. Outside herb gardens die in the wintertime. Indoor herbs grown under a grow light continue to grow year around, so you can flavor your favorite dishes with fresh herbs -- even in January.
Flowers
Late frosts, torrential rains and high temperatures can all kill the flowers in your garden outside. Protect your flowers against the outdoor elements while giving them the sunlight they need by growing them indoors under a grow light. Grow lights also enable you to grow flowers all year round. When there's snow on the ground, for example, you can look at and smell newly bloomed African violets, orchids or hibiscus in your home.
Survival Preparation
In case of natural or man-made disaster, you probably stock up on bottled water, canned food and blankets. Grow plants and produce in your basement using a grow light. If a disaster diminishes food resources, pollutes the air or rioters plunder grocery stores, you will have plants in your basement to produce clean air and fresh food to eat. Grow lights are electrical, so if you lose power, the lamps will no longer work, but at least you'll have plants you've already grown.
