Wide Spectrum vs. Narrow Spectrum LED, Which One Is Better for Cucumbers

Cucumbers are one of the most common crops for indoor growing. Growing cucumbers indoors helps cultivate healthy and productive cucumbers, especially during the autumn and winter seasons. When it comes to indoor growing, one of the most important factors to consider is lighting. It can affect the photosynthetic efficiency and yield of greenhouse cucumbers. In recent years, LED grow lights have become increasingly popular due to their energy efficiency and versatility. However, not all LED grow lights are created equal. There are two main types: wide spectrum (also called white light) and narrow spectrum.

If you are growing cucumbers indoors, you might be wondering what type of LED light is best for your plants. In this blog post, we will compare wide spectrum and narrow spectrum LED lights and see which one is better for cucumbers. Let’s take a close look.

What is a wide spectrum LED?

Wide spectrum LED is a kind of light-emitting diode that produces light across a broad range of wavelengths in the visible spectrum. It is also called full spectrum or white LED light because it produces a white light that resembles natural sunlight. Wide spectrum LED light has a more balanced and continuous distribution of wavelengths, from about 380 nm to 700nm. It is designed to mimic the sun’s light and provide all the necessary wavelengths for plant growth.

What is a narrow spectrum LED?

Narrow spectrum LED light is a type of light-emitting diode that emits light at specific wavelengths in the visible spectrum, usually blue and red. They are also called monochromatic or single-color LED lights. These wavelengths are known to be important for plant growth and development, as they stimulate the absorption of chlorophyll and the production of carbohydrates. Narrow spectrum LED lights are designed to target specific plant responses and enhance certain aspects of plant growth.

Wide spectrum vs. Narrow spectrum LED, which one is better

Cucumbers require a lot of light to thrive and produce a good yield. Both wide and narrow spectrum LEDs can be used for growing cucumbers. So which one is better? Let’s check out the comparison.

Cost

Generally, wide spectrum LED lights are more expensive than narrow spectrum LED lights. Because wide spectrum LED lights require more complex technology and materials to produce a broad range of wavelengths. In contrast, narrow spectrum LED lights are cheaper and easier to manufacture.

Light quality

One of the main advantages of wide spectrum LED grow lights is that they provide a more balanced light source. This means that the light is distributed more evenly across the entire visible spectrum, which can help promote healthy plant growth. Additionally, a wide spectrum can provide both blue and red light throughout the growth cycle. Narrow spectrum LED grow lights, on the other hand, are best suited for specific stages of plant growth. For example, blue light is typically used during the vegetative stage, as it promotes leaf growth and chlorophyll production. Red light, on the other hand, is best used during the flowering stage, as it promotes bud formation and flower production. While narrow spectrum LEDs can be useful in these specific circumstances, they are not as versatile as wide spectrum LEDs.

PlantaLux has carried out tests on the cultivation of greenhouse cucumbers. The table below shows the results of cucumbers grown in broad spectrum LED and narrow spectrum LED.

As the table showed, wide spectrum LED lights are better for cucumbers than narrow spectrum lights.

Energy efficiency

The energy efficiency of wide spectrum LED lights versus narrow spectrum LED lights depends on the specific LED chips used and the driver circuitry. In general. Both wide and narrow spectrum LED lights can be designed to be highly energy-efficient.

However. It is important to note that the efficiency of LED lights is not solely determined by the spectrum of light they emit. Other factors, such as the quality of the LED chips, the driver circuitry, and the heat dissipation system, can also affect the energy efficiency of LED lights.

Conclusion

From this comparison, we can conclude that wide spectrum LED grow lights are generally considered to be the better option for growing cucumbers. They provide a more natural and balanced light that promotes healthy plant growth. Although they are more expensive than narrow spectrum LEDs, they help growers achieve higher production and yields. However, narrow spectrum LEDs can be used for specific stages of plant growth. Ultimately, the choice between wide spectrum and narrow spectrum LED grow lights will depend on your specific needs and preferences.
