You should know this about LED grow lights

Unfortunately, the sun does not shine at full strength all year round in the Netherlands, or do you have many dark spots in your home where it is difficult to place plants? LED grow lights offer a nice solution for this. LED grow lights have been specifically developed to promote the growth of your plants. Even in a room where there are no windows. You can also use them to give your plants a boost in winter when the days get shorter and the sun shines less brightly. In this blog post I will tell you all about grow lights.

Different types of grow lights

Nowadays, most grow lights use LEDs, which consume little power and do not get hot. There are many different types, such as small bulbs that you screw into an E27 fitting, but also LED strips. There are also complete fixtures available that incorporate LED panels, which are generally more powerful and can cool themselves better. Each lamp has its advantages, an E27 LED grow lamp is intended for lighting 1 to 3 plants, but with an LED strip you can illuminate many more plants.

When do you use an LED grow light?

There are various reasons for this. Suppose you have a dark corner in the house or a room that does not receive daylight and you still want to grow plants there, then an LED grow lamp can offer the solution. You can also only use an LED grow lamp in winter as soon as the days get shorter and it is a lot darker in the house. If you can't move your plants to a suitable spot, an LED grow light can help keep your plants healthy. It is also possible to use a grow lamp to grow seedlings and to give your cuttings extra strength during the winter.

How long should an LED grow light be on?

You don't have to have an LED grow lamp on 24 hours a day, which is also not good for plants because plants also have a day and night rhythm. At night, when it is dark, the plant has a rest period, which is necessary for its development. You can do this by means of a timer, some LED grow lights have a built-in timer. The maximum number of hours that the lamp is on is 16 hours, which is perfect if you grow cuttings and seeds. For stable growth of an adult plant, 10 to 12 hours of light is required.

What should you pay attention to?

At the moment there are many different types of grow lights. In this blog we explain which light spectra there are. White light is currently the most popular, but not every white light is the same. When an LED grow lamp is intended for growth, it will only contain bright white LEDs. These have the color temperature of 6,500K. There are also lamps intended for the growth and flowering of your plants, these lamps use a white full spectrum. Often a combination is made of 3000K and 6,500K LEDs with sometimes extra additions such as UV and infrared. Less popular are the LED grow lights that use red and blue LEDs, because the light color is purple/pink. This color is not experienced as cozy and you cannot view your plants properly, so that you do not notice discolorations on your plant in time.

Can you use a normal lamp as a grow light?

A normal LED bulb or energy-saving lamp is intended to create light as efficiently as possible that people experience as pleasant. Plants need a different kind of light and also need more light than what a bulb can provide. A normal lamp also does not provide the correct spectrum, so that your plants do not receive enough blue or red light.

Tips when using your LED grow light

Make sure that the plants do not touch the LED grow lamp, as this causes the light to shine too intensely in one spot. This can damage the plant. With most LED grow lights you don't have to worry about damaging your plant as long as the blisters don't touch the grow light. You can adjust the height of most LED grow lights so that you can prevent this. If you use a smaller lamp, you can hang it close to the plants, a height of 10 to 15 cm is ideal. A larger lamp can also hang a bit higher so that you create a larger light surface, which allows you to provide light to several plants.
