Will seeds germinate under LED light?
LED lights provide more than enough direct lighting to grow young vegetable and flower seedlings strong and true. They also happen to be inexpensive to operate, without the humming noise many grow lights can have.
Are LED lights good for seedlings?
LED plant lights use less energy and emit less heat than compact fluorescent lights, reducing costs and simplifying temperature control in enclosed environments. Go with full-spectrum LEDs (which don't look purple) for growing seedlings, propagating plants, and perking up houseplants in winter.
What light is best for starting seeds?
Sowing seeds indoors under fluorescent lights is the easiest way for the home gardener to control growing conditions and grow healthy transplants. Incandescent bulbs give off more heat and less light (mostly red) than fluorescent tubes and will not produce good transplants by themselves.
How far should LED lights be from seedlings?
There is no universal rule for setting the distance but it's recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.
What color LED lights for seedlings?
Blue light regulates plant growth, which makes it ideal for growing foliage plants and short, stocky seedlings (but too much will result in stunted plants).

What color grow light is best for germination?
Experts from Thompson & Morgan report that light in the red wavelength range promotes germination, while blue light impedes it. This is because the red light affects a plant pigment, phytochrome, that is within the seeds. But if the plants are below a thick canopy of leaves, blue light may be needed as well.
How many hours of light do seeds need to germinate?
16-18 hoursThe most important thing to consider and deliver is adequate plant light. Seedlings need more light than full grown plants, ideally as much as 16-18 hours a day. Additional light may be required for seeds started during the winter months.
Is red or blue light better for seedlings?
Plants that receive plenty of blue light will have strong, healthy stems and leaves. Red light is responsible for making plants flower and produce fruit. It's also essential to a plant's early life for seed germination, root growth, and bulb development.
Which is better for plants LED or fluorescent?
When it comes to energy efficiency, LED grow lights beat out the best fluorescent grow lights, hands down. When comparing lighting efficiency, it's important to look at the light levels delivered to plants rather than just the electrical watts.
How many hours a day should a grow light be on seedlings?
12 to 16 hours per dayKeep the lights as close to the seedlings as possible without touching them (2 to 3 inches). When seedlings first appear, keep the lights turned on for 12 to 16 hours per day. To reduce your hands-on time, use a timer to turn the lights on and off automatically.
How long to leave grow lights on seedlings?
Leave the grow lights on for 14 to 16 hours per day to provide light for the young seedlings. It's best to turn the light on early in the morning and turn it off around dusk. Your seedlings will still thrive if you deviate from this schedule.
What type of light do you use for seeds?
In simple terms, fluorescents use their energy to produce more light than heat comparatively. And there are two types commonly employed for starting seeds, tube types and compact fluorescent lamps (CFL's). For folks that are pretty new to growing indoors or have a small space, the CFLs can be a great option. These compact types fit into a standard lamp socket, unlike tubes that require a ballast/shop light fixture.
Why do plants need grow lights?
As anyone who has relied on the light from their house fixtures and a south-facing window know, plants need greater light quantity and quality for healthy growth. And when gardeners want to get a jumpstart on their annual herbs, flowers and veggies, dedicated grow lights are necessary to produce quality plants from seed.
Why do artificial lights stay on longer?
Because the quality of light is less from the lights than light from the sun , artificial lights must stay on for a longer period than normal day length. Some LEDs are more susceptible to degrade when running for more than 18 hr during the day—follow instructions provided with your light.
What is LED lighting?
LEDs are unique in their ability to produce a high quantity of light with lower energy requirements—some models producing more than twice the amount of light per watt compared to fluorescent. Some LED systems are designed to improved efficiency by delivering red and blue spectrums of light exclusively (the wavelengths required for plant growth). This is why some LEDs give off a purple glow, unlike full spectrum lights that emulate daylight. But as we know, LEDs, like those available for home lighting, come in more neutral white colors that will also work for seed starting. You can even buy led tube lights that will fit in your shop light ballast and require less energy. (pictured below).
Why use dual band LED?
Dual-band LED, better photosynthesis efficiency and so light can be held at a greater distance from plants.
How to tell if a seedling is bleached?
If your seedling leaves look bleached, move the light back and if the seedlings are stretching or leggy bring it closer till you find the sweet spot . With both LEDs and fluorescent look for lights that include the cooler blue spectrum, these will often be marked as 5000-6500K (Kelvin).
Shapes and sizes
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. The best size and shape for you depends on the orientation of your seed starting setup.
Light color
Plants use light in the photosynthetically active radiation spectrum, which includes wavelengths ranging from 400 (violet) to 700 (red) nanometers. Typically, plants use more blue and blue-green light when they are seedlings, and more red light later on in their life cycles when they begin to flower and produce seeds.
Light intensity
Grow light bulb options. Bulbs range in price, light intensity, and light spectrum.
How To Set Up Your Indoor Grow Light System?
Depending on your demands, you might need one or some wire shelving models to grow seeds and set up a light system on them.

Can you use LED shop lights to start seeds?
But as we know, LEDs, like those available for home lighting, come in more neutral white colors that will also work for seed starting. You can buy led tube lights that will fit in your shop light ballast and light up the entire room.
Are all LED lights grow lights?
Even though they emit some of the wavelength necessary for plants, regular lights can’t be used as grow lights. Plants require a certain amount of light to grow. Red and blue light are what grow lights are designed to emit. If you want to grow your own plants, you’ll need to buy a grow light from a reputable manufacturer.
Can plants live under LED lights?
Growing light-loving plants such as orchids, as well as indoor seed starting, can be done with the help of grow lights. With a set of grow lights, you can grow many plants indoors, including houseplants, orchids, and succulents.
Can LED lights burn plants?
LED lights deal with heat more effectively than other light types. Plants can grow closer to LEDs than other lighting types. Usually crops can grow right up to the edge of the LED light.
How many lumens do seedlings need to grow?
If you’re growing just a single standard tray of seedlings, using a grow light that emits 3000 lumens per sq. ft. will suffice. If you want to grow more than one tray, you’ll need to increase the brightness of the light.
What light is best for growing seedlings?
If you want your plants to get the quality, intensity, and duration of light that they need to grow, a fluorescent or led lamp is the best choice. Fluorescent lamps are the most common type of lighting used in the home garden. Fluorescent bulbs are made up of a series of tubes that are connected to a light source.
What are the disadvantages of LED grow lights?
One disadvantage to LED grow lights is their psychedelic appearance. Since plants use only blue and red wavelengths of light for photosynthesis and growth, LED grow lights use combinations of blue and red bulbs that result in an intense purplish glow.
Do all blue-red LEDs produce the same amount of light?
However, because LEDs are designed to emit light in a very specific wavelength, and not all blue-red LEDs produce an equal amount and quality of light, research continues on how different species of plants germinate and perform under different types of LEDs.
Do all seeds need light?
Not all seeds require light as a condition for germination. Some species need dark for proper germination, such as annuals like larkspur (Consolida species). Research is still mixed as to whether LEDs or fluorescents are better for seed germination; some research at Michigan State University suggests that seed germination rates are better under LEDs, while other studies done at Wofford College in South Carolina indicate that no difference exists in germination rates between plants started under LEDs and fluorescents, and that fluorescents may actually spur better early root development than LEDs.
Why do plants need artificial lights?
There are many types of artificial lights in different styles and sizes to fit your needs and budget. Light is one of the most important factors for growing houseplants.

How to keep plants healthy?
But even with LED and fluorescent lights, maintaining a proper distance helps to ensure healthy plant growth.
What plants grow well in fluorescent light?
Medium-light plants. Medium- and low-light plants like this pink Begonia and two Chinese evergreens ( Aglaonema) grow well in fluorescent-lit places like an office lobby. These plants grow well indoors in areas that are well-lit such as in east-facing windows or near a west-facing window, but out of direct sunlight.
Why do plants need energy?
Plants require this energy in order to grow, bloom and produce seed. Without adequate light, carbohydrates cannot be manufactured, the energy reserves are depleted and plants die.
How to choose plants for indoors?
Then choose plants with light requirements that match your indoor environment.
What is an LED grow light?
Most LED grow lights you can find today are “full spectrum” lights, which is sort of a buzzword that means you can use them for vegging and flowering. But there are also models outfitted with a switch that allows you to change the light spectrum according to the phase. Moreover, some LEDs are made only for veg—emitting a bluish light that supports fast and vigorous growth—while others are made for bloom, giving off a reddish light to support bud development. So, before you get an LED light, make sure it’s the right type. For most growers, a full spectrum LED is likely what you'll want.
What kind of lights do weed growers use?
In the past, weed cultivators largely used HID lights —with MH (metal halide) lights used for vegging and HPS (high pressure sodium) lights employed for flowering. HID lights are still viable, and they have a great track record amongst home and commercial growers alike.
