LED Grow Lights: The most frequently asked questions

Are you looking for information about how LED Grow Lights work and how exactly you grow with them? Look no further, it's here.
The LED grow light is becoming increasingly popular in horticulture and greenhouse construction. And that's not surprising. A LED grow light gives you plenty of benefits! In this article you can read the benefits and the most frequently asked questions about LED grow lights.

What is an LED Grow Light?

An LED grow lamp is a lamp that is used in horticulture and greenhouse construction to grow (and bloom) plants and flowers. After many years of experimenting with LED, it is possible to achieve a higher yield of flowers and fruits with a lower wattage. Unlike a normal HPS lamp, sodium or incandescent lamp, LED produces less heat, making high temperatures a thing of the past.

How does that work, a Grow Lamp?

We also recently wrote about the exact science behind LED grow lighting, but that may be going a bit too far for now. The big difference with old-fashioned HPS or sodium lamps is in it light spectrum. This light spectrum is reflected in the value PAR. The amount of PAR says something about photosynthesis, the more PAR, the more photosynthesis and the better the plant can grow and bloom.

Which lamp do I need for my grow room?

The lamp you need depends on the room, so measure the floor. The length times the width equals the amount of m2. The best results are achieved from 40 to 50 watts per square meter, so look there LED grow light also on.

How high do I hang an LED Grow Light above the crop?

The data below are recommendations and may differ per type of plant. The number of recommended centimeters is measured from the top of the plant.

  • Sowing/germination: +/- 70 CM
  • Growth: +/- 70 to 100 CM
  • Growth: +/- 45 to 100CM
  • Flowering: +/- 25 to 50 CM

How long should an LED Grow Light be on?

A separate button for growing and blooming is not present on every lamp, but this is not necessarily necessary. It is a good idea to work with an external timer (or use the timer in the lamp - if present) so that these times are achieved.

  • Sowing/germination: 18 hours on, 6 hours off (dark) - possibly 20 at 4
  • Growth: 18 hours on, 6 hours off (dark) - possibly 20 at 4
  • Growth: 18 hours on, 6 hours off (dark)
  • Flowering: 12 hours on, 12 hours off (dark)

Which LED Grow Lights are available?

Light spectrum of an LED Grow Lamp

An LED grow lamp from the LED department store is often equipped with a 12-band spectrum as standard. In addition to the regular colors red and blue, the LED grow lights also have orange, white and UV light, infrared light and 'flower boosters' that are in the far-red spectrum. This makes the 12-band spectrum a full spectrum.

Which growing conditions are important?

Besides a good one LED grow lamp , there are a number of factors that can be extremely important for the growth and flowering of a plant (or flower). Temperature, humidity and air supply have a direct effect on the photosynthesis of the plant. The perfect temperature is between 23 and 30 degrees Celsius. As for the humidity we recommend staying between 50% and 70%, using an air supply and air extraction that is in balance. PH values vary per plant, but in most cases a value of 6 to 6.5 is sufficient.

Which grow light should I get?

We have a wide range of LED grow lights , we understand that it is sometimes difficult to make a good choice. Some things to remember are:

Benefits of LED Grow Lights

Compared to regular grow lights (HPS sodium), deliver LED grow lights have a number of important advantages:

  • Up to 60% power savings
  • Healthier growth and flowering of plants and flowers
  • Less heat: A more easily regulated temperature in the growing room or greenhouse
  • Longer lifespan of the lamps (up to 50,000 hours)

Does LED work in combination with HPS or sodium lamps?

Yes, it is no problem at all to mix LED and HPS. We get this question regularly because growers often first want to replace a number of 'old-fashioned' lamps to see if it works. Logical of course, but try to do this alternately so that there is a good light mix of LED light and white/yellow light. There will be a decrease in heat and therefore also in the use of water and nutrients.

Other tips when purchasing

In larger growing areas (from 5 square meters), a good distribution of light is important. Multiple grow lamps with a slightly lower wattage probably provide more light distribution on the sides of the crop than one lamp with a high wattage. High light intensity is good if it only concerns a few square meters. For larger grow rooms, choose to have approximately the same light intensity everywhere.

As a greenhouse horticulturist or grower, can I borrow a lamp?

As a company, you can contact us for LED grow lighting and the installation of LED systems. We are happy to work with you to find a suitable lighting solution. LED growth lighting, especially in greenhouses, is still relatively new and sometimes requires some experimenting to get the right light composition. The light spectrum and the correct par value play an important role. The LED Department Store therefore offers the opportunity for a test phase in which you can try a lamp free of charge. Totally free!

You don't want to switch all at once? No problem, it can also be done gradually. For example, you can consider replacing current lamps that no longer work. This way you gradually invest in your company and ultimately save many euros. We can create a free test setup with you. Therefore, register as a company through us Contact Form .

I want proof! Is a breeding report available?

The LED Department Store promises good growing results, we understand that you want to see this substantiated with, for example, a report or results overview. You will regularly find breeding reports on our Blog . See more? That is possible, we have a report of each lamp available on request.

What is the lifespan of an LED grow light?

LED grow lights are often used in environments with high humidity. Our lamps perform well under such conditions, which is why we provide a minimum 2-year warranty in most cases. On request it is even possible to make grow lights IP65 (waterproof), please contact us. The standard lifespan is often around 50,000 burning hours, because we use high-quality LEDs from the CREE brand. Even after the warranty period, we are happy to remain your point of contact if something is wrong with a lamp. The modular construction makes parts often easy to replace. We are happy to advise you what is best to do at that moment. It goes without saying that you can expect the service you are used to from us.
The lifespan of our LED business lighting and LED lighting for sports fields is also 50,000 hours. With normal use during office hours, these lamps will last at least 10 years. So it is not only the energy consumption that makes the purchase of LED lighting interesting, but also the lifespan.

Where can I find an instruction manual?

Most LED grow lights require one instructions for use included. In all other cases, it has been decided not to further burden the environment with paperwork, so you can simply download the instructions from us. find blog . If you still have questions, you can ask them via our chat function or the Contact Form .

Why has UV light been added to your lamps?

UV light is good for the growth and flowering of your plant or flower. UV light has a good effect, especially in the growth phase, because it helps photosynthesis get started. Just like infrared light, UV light is not visible to the human eye, see also below. It then seems as if an LED does not work, but in fact that is of course not true. UV light is not included in every LED grow light, see the products for more information. UV light is an additional stimulus in the flowering phase of the plant, just like far-red (from 670 nanometers).

It seems as if a number of LEDs are not working, is this correct?

If all but a few LEDs work, then this is probably one of the Infared (IR) LEDs. This light is not visible to the naked eye. How did that happen? The cones in our eyes all contain a different color pigment and therefore have their own maximum sensitivity. IR light falls outside the scope of our sensitivity maximum, making it appear as if no direct light is coming from it. If you have ordered a 7-band spectrum or a 12-band spectrum, it is common that such LEDs are present in the lamp. It seems as if there is a very small point of light in the distance from the LED, so we sometimes get questions about whether there is something wrong with the LED. We advise you not to look too much into bright light with your naked eye, but if you want to do so, at least use sunglasses. Do you want to be sure that there is nothing wrong with the lamp? No problem, feel free to name it Contact on.

How do I know which light spectrum I need?

We've written about this before because we've had a lot of questions about the differences in LED Spectrums . The LED spectrum you need is different for each stage the plant is in, namely germination, pre-growth, growth and flowering phase. During germination and the pre-growth/growth phase, white, blue and red light is important, look for the exact nanometers in the article .

What is the warranty on LED grow lights?

We strive to deliver sustainable and high-quality products, fortunately we have succeeded so far. A quality product also comes with a warranty, we like to be clear about that. The LED Department Store gives a standard 2-year warranty on every LED grow light unless stated otherwise. The warranty period is sometimes longer to 3 or 5 years and in some cases slightly lower. Every LED grow lamp/LED growth lamp that we sell states what the warranty is. If you have any questions about the warranty on a product, you can always contact us Contact to withdraw.

If I also use daylight, isn't additional lighting with LED superfluous?

Additional lighting with LED grow lights is never a bad thing, it even provides extra benefits. The light from an LED grow lamp provides an extra stimulus for the flowering phase because specific LEDs with high PAR measurements activate photosynthesis. Be careful not to upset the rhythm of the plant. By this we mean that the plant needs rest and prefers to be in the dark. After all, we humans also need to sleep in order to be able to start a new day rested. That's how it works with the plant. When the flowering phase is active, it is fine for the plant to receive only 12 hours of light.
Returning to the question, it is good to shine with LED. It can therefore do no harm to provide your plant with extra LED light during the dark days.

For which crops can I use your grow lights?

LED grow lights can be used for any type of crop. Because most grow lights emit a different light, it is good to find out which type of light your plant needs, here is a brief guideline:
My plant only needs to grow and not bloom: You can do it with a 2.band, 4-band, 5-band or 7-band spectrum
My plant has a long growth phase and only then needs to flower: Broad beans, for example, generally have a longer growth phase before the bean actually arrives: 5-band, 7-band or 12-band spectrum.
My plant should mainly flower and bear fruit: 12-band spectrum

Is the par value of LED lighting important?

The par value is an important indicator for photosynthesis. In fact, PAR is the benchmark for the growth and flowering of plants and flowers, without PAR a grow light does not work. PAR is shown graphically in a spectrum, see the image below. Because we have had many questions about the par value, we have one article written. If you still have any questions, you can contact us.

Can the growth and flowering of the Apollo lamps be controlled yourself?

The Apollo grow lights do not have a separate button for growth and flowering. There is only one type of original Apollo that contains this and that is the variant with a control panel. The LED Department Store has noticed that the current control panel does not meet the needs and is too complicated. That is why we do not sell this lamp. Other Apollo lamps that contain 2 buttons (1 for growth and 1 for flowering) are not the original Apollos. There is a good chance that it is a Chinese LED grow light that did not come from the original factory. Guarantee right to the front door.

What is the light distribution of Apollo 10?

The Apollo 10 is one of the best-selling LED grow lights. This is because the price-quality ratio is very good. The light distribution is very good, the lamp covers an area of ​​1 by 1.20 meters. This is at a hanging height of approximately 75 cm above the crop. You can keep it higher, but that is at the expense of the light intensity. At 75 cm you have an ideal light mix.
