Why led Light is needed for transplanting seedlings

Led lights are also very important for transplanting seedlings. Led lights are an incredibly useful tool for growing vegetables, herbs, and flowers indoors. You can also use led lights to keep houseplants happy and healthy, grow microgreens, or even provide supplemental light inside a greenhouse. But, where to start? If you are new to using LED lights to transplant seedlings, then you have come to the right place!



What is led light

First of all, we need to know what LED light is? In fact, the full name of LED light is a light-emitting diode. A light-emitting diode is a semiconductor device that emits visible light when an electric current passes through it. It’s basically the opposite of a photovoltaic cell (a device that converts visible light into electrical current).


Why use a grow light?

Seedlings depend on such soil for transplanting. Exactly the plants depend on light for survival. Just like why LED lights are needed for planting saplings. Through the process of photosynthesis, plants use energy from sunlight and convert it into the chemical energy that is used for their growth. In most cases, The amount of light a plant receives is directly related to how strongly it grows. Where there is a lack of adequate natural sunlight, using LED lights to provide supplemental lighting and supportive plants is an easy and excellent way. Have you seen a very tall sapling learning around? The seedlings spread out in search of light. Seedlings are not very tall! When there is not enough light, the seedlings can lean, the veggie seedlings become weak, thin, and weak (also known as “leggy”) which is at risk of breaking.

So, LED lights can give enough light, otherwise, they may struggle to improve.

One of the best ways to prevent tree seedlings and grow the healthiest, most successful plants is to use LED lights inside. Adequate lighting should be provided to protect the seeds inside the house. Especially in the winter months when it is daylight Already rare; This is the time when most gardeners start sowing for the spring and summer seasons. Just then the LED lights are light enough to Keep the seedlings small, stocky, and strong. However, bright windows and ambient light are usually sufficient for most house plants.

What Color Led Light Does transplanting seedlings Best In?

The short answer is Blue light. But it’s not quite that simple. For one, transplanting Seedlings great in natural sunlight. Sunlight is not blue. It is…yellow? White?

The color of light DOES affect transplanting Seedlings, but the effect is more noticeable under low light intensity. Red & blue light are most effective for seedlings, while yellow & green have minimal effect. UV light can damage plants, causing leaves to burn. Growers often use supplemental light to optimize plant growth.


When plants are just seedlings and are first light, blue light should be used. Blue light is very important to the beginning of seedling growth because it increases the amount of chlorophyll that is formed. Some seedlings will not germinate without blue light. Red light and blue light are important when the seedlings are mature and beginning to flower.

This helps them to produce more leaves and more crops.

Violet light can be used at any time of plant life to enhance the color and taste of a plant.

First, here’s a quick summary, with the following extended information:

  • Ultraviolet (10 nm to 380 nm) – No exposure produces good growth
  • Violet (380 nm to 450 nm) – enhances the color, taste, and aroma of the plant
  • Blue (450 nm to 495 nm) – Increases the growth rate of plants
  • Green (495 nm to 570 nm) – Increases chlorophyll production and is used as a pigment for proper plant viewing
  • Yellow (570 nm to 590 nm) – Plants show less growth than blue and red light
  • Red (620 nm to 720 nm)- When combined with red-blue light it yields more leaves and crops depending on what is being cultivated
  • Far Red (720 nm to 1000 nm) – Accelerates phytochrome transformation which reduces the time it takes for a plant to go tonight. This allows the plant to produce a larger yield

Some objects will absorb the wavelength, and others will reflect because the items are why they color that. For example, a leaf is green because it absorbs the wavelength of all visible light except green – green is reflected.

Black and white are not considered colors because black absorbs all the wavelengths of visible light, while white reflects them. This is why black matter heats up faster in sunlight than white matter.

How far should the seedlings be from a grow light?

The light should not be too far from the beginning of seedling transplantation. It is better to keep the light 2-3 times above the leaves of the tree. 

So first, your fixture will hang directly over the plastic lid on the tray (but don’t touch!).

Once your start is long, and you open the lid, then you need to adjust the lights regularly so that they are always on top.

The leaves should never touch the bulbs, otherwise, they may burn. So be sure to check them every day and turn on the lights if necessary. Using a compatible hanger will make this much easier!

Rotate the tray every day if you notice that any seedlings around the edges are reaching, or not growing, as well as those that are under direct light.

FAQS About Lighting for Transplanting Seedlings

I’ve talked a lot about lighting for seedlings so far in this article, but you may have a few more questions. So now I will answer the most frequently asked questions. Post your question in the comments below if it is not answered here.

Are LED lights good for seedlings?

Your seeds must be subjected to consistent heating to keep the propagation process going. Signs of successful germination will include small sprouts popping up from the dirt, and leaves starting to form from those sprouts. It is at this point that you may remove your tray from the seedling mat and turn it off.

Do you need a grow light for seedlings?

Seedlings need 14-16 hours of light per day, without fail. Don’t leave them 24 hours a day though. Like us, they have to rest at night. So plan to keep your artificial lights on for 14-16 hours during the day and turn them off overnight.

How far should LED lights be from seedlings?

For seedlings, LED grow lights should generally be mounted 24-36 inches above the plant canopy – however, this depends on the power source (wattage) of the light source.

Do seedlings need 24 hours light?

No, and you should not keep seedlings under the grow light 24 hours a day. Like us, they have to rest at night.

It is important to follow a normal sunlight pattern, otherwise, your seedlings will be damaged when taken out. So keep the lights on for 14-16 hours during the day and off at night.

Do seeds grow better in light or dark?

Most seeds germinate best when they’re placed in the dark. The presence of light, which is crucial to seedling development, may actually stunt the process of germination.

Do you use Grow Light during germination?

It depends on the type of seed. Some shoots need light, others do not. Always check the packet for details, or research specific varieties before planting.

Adequate lighting is crucial for success with seedlings, and it will give them a healthy start in life. You will also find that it makes your work easier with less waste and frustration.
