![]() LEDs are usually more expensive than fluorescent bulbs, but they are very energy-efficient and long-lasting. There are other types of grow lights like sodium vapor lights, but they are harder to find and more commonly used in commercial greenhouse settings.įor many years, fluorescent shop lights were the go-to seed starting bulbs for gardeners, but LEDs have quickly replaced them as the standard choice. Most gardeners use either fluorescent lights or light-emitting diode (LED) bulbs. Bulb technologyĪ small shop light can provide coverage to one or two trays. If you’re starting multiple seedling flats, a longer shop light will allow fairly uniform coverage across your trays. A better, usually more expensive option, would be a tube light that is the length of your seedling tray so that the light is more evenly distributed. So, if you only have one tray of seedlings, a single bulb model will likely work fine, especially if you have some natural lighting to supplement it like a bright window. ![]() If it’s off to the side or too high above them, they will stretch to reach it, resulting in thin, weak stems. Ideally, your light should be positioned directly above your seedlings. The best size and shape for you depends on the orientation of your seed starting setup. Grow lights are sold in a variety of shapes and sizes, from bulbs that look like those you would put in a lamp, to clip-on rods, to long shop lights. Let's break down which options may best suit your seed-starting needs. They come in a variety of colors, shapes and prices. Grow lights should be on for at least 14 but no more than 18 hours per day even indoor plants need a minimum of 6 hours of darkness each day.If you’ve shopped for grow lights recently, you have likely noticed that there are a lot of different options for seed-starting lights. Plants grown under lights indoors need more hours of light than the same plants do outdoors. To be most effective, each light should be a specific distance from the plants: Fluorescent lights should be 3 to 12 inches above the tops of the plants HIDs, 24 to 60 inches and LEDs, 12 to 24 inches. Remember, too, that each type of grow light provides a different amount of light.Or, stabilizing the light(s) and setting the planters on a stack of books, removing volumes as needed to lower the maturing plants. Common options include suspending the lights from chains above your plants (e.g., on the ceiling or a sawhorse) and adjusting the chains as the plants grow. Think about how to position the light(s) over the plants so that you can easily alter the distance between the lights and the plants as they grow.For the healthiest plants, use a combination of both blue and red lights-or a full-spectrum bulb, which emits both wavelengths of light. Plants that are grown for their fruit or flowers require the addition of red light, which encourages blooming. Edible plants that are grown purely for their leaves-such as salad greens and herbs-can be grown under bulbs that primarily emit blue light, as this encourages chlorophyll production and foliar growth. Figure out what sort of plants you wish to grow. ![]() This will enable you to calculate how many bulbs you’ll need.
