what lights to use for seed starting

by Solon Bartoletti Published 2 years ago Updated 2 years ago

Medium light

  • A medium-light plant would be suitable for east-facing windows or located near a west-facing window, but out of direct light.
  • You would need artificial lighting for starting seeds in medium light.
  • Like the low light plants, these plants will not dry out as quickly. Avoid overwatering by feeling the soil.

Light color
If you are just using grow lights to start seeds or to grow leafy vegetables, stick to lights that are labeled either as blue-green spectrum or balanced light spectrum. It is increasingly common for lights to be labeled “for greens and seeds” or “for flowers and fruit”.

What kind of light do you use for seedlings?

For most home gardeners, a plug-in shop fluorescent or LED light fixture is the perfect type of light to use for seed starting. When shopping for fluorescent lights, look for high-output, full-spectrum (sometimes called “daylight”) bulbs.

How to choose the right grow light for your house plants?

Check the packaging to see what type of light is emitted by a grow light before buying it; grow lights tend to be labeled as blue, red, or white/balanced light. Blue light or mixed light bulbs are suitable for starting seeds and leafy greens, as well as non-flowering house plants.

Can you start seeds without artificial lighting?

You may be able to start seeds without artificial lighting, but seeds that need more time indoors, such as tomatoes and peppers, may become leggy without extra light. High-light areas can be warm, making plants dry out faster.

How high should the light be from the seedlings to grow?

Supplemental lights need to be oriented relatively close to the seedlings to be effective and therefore need to be adjustable in height to accommodate the growing plants. For most fluorescent fixtures, the seedlings should be 4 to 6 inches from the light source.

What type of light do you need to start seeds indoors?

fluorescentFor the average home gardener starting seedlings indoors, a fluorescent or LED lamp will usually be the best choice to ensure that your plants get the quality, intensity, and duration of light they need to stay in peak condition.

Can you use regular LED 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 even buy led tube lights that will fit in your shop light ballast and require less energy.

What color of light is best for starting seedlings?

For growing seedlings indoors, choose a grow light that is described as “full-spectrum” or broad spectrum. I recommend the same for houseplants too. With a full-spectrum light, you're getting a good balance of both blue and red light – and the closest thing possible to natural sunlight!

Should I use grow lights to germinate seeds?

However, grow lights are necessary for sprouted seedlings unless they are in a sunny window or otherwise getting direct sunlight. The only benefit of grow lights before germination is that they can provide extra warmth which helps speed up germination.

What is the difference between a grow light and a LED light?

Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering, respectively.

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.

How far should LED grow light 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 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 long should seedlings be under blue light?

For the first three to four weeks, leave the light on for at least 18 hours. After the first month you can decrease light exposure to 10-14 hours a day. Plants that need a lot of direct sun like peppers and tomatoes should be on the higher end of that spectrum.

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.

Do seeds need 24 hour light?

Do seedlings need 24 hour lighting? No, and you should not put seedlings under grow lights for 24 hours a day. Just like us, they need to rest at night. It's important to follow a normal sunlight pattern, or your seedlings will suffer when it's time to move them outside.

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 artificial lights stay on longer?

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.

Can you hang grow lights on a wire rack?

The grow lights need to be suspended from above so they shine down on the plants. So, you’ll either need to mount them or hang them. This is why I love using a wire rack. With a simple s-hook and metal chain I can hang my lights from the shelf above and move them up and down as the plants grow.
