Light for plants

Growshop.cz offers only top-quality products, fully compliant with the demanding conditions of grow rooms. We all probably know that a grow room is a space where temperatures change, where a significant amount of water vapor evaporates, where intensive work is done. That is why we only need the highest quality lights. At the same time, any outage has a drastic effect on the result of the entire operation.

Therefore, you cannot rely on brands designed to illuminate, for example, a workshop, where if the light fails, it is replaced and nothing happens. For growing plants, we only need 100% proven products, and growshop.cz brings them to the Czech market.

Light spectrum for plants - what kind of light do plants need

Photosynthesis is the process by which plants use light energy to synthesize organic compounds from carbon dioxide and water. This process is crucial for plants because it allows them to produce food and obtain energy. For proper photosynthesis, plants depend on light, which is essential for their growth and survival.

Photosynthesis takes place using photosynthetic pigments, primarily chlorophyll, which is found in the green parts of plants, such as leaves and stems.

The light spectrums in the blue and red light range are most suitable for plant growth and development. While blue light stimulates growth and leaf formation, red light promotes the formation of flowers and fruits. Other parts of the spectrum are less important for plants, but can still contribute to growth.

If we want to provide plants with optimal conditions for growth with artificial lighting, it is important to choose the appropriate spectrum and intensity of light. Modern LED technology allows us to create lighting with precisely defined spectra that are ideal for growing plants. For growing herbs for aroma and resin content, light in the red and infrared spectrum is most important.

Another factor that affects plant growth is the length of light. Plants need a certain number of hours of light per day to grow and develop. For most plants, the optimal length of light day is 16-18 hours.

When the light period shortens, plants recognize that the end of their life cycle is coming and put all their energy into creating the next generation, i.e. flowering and fruiting.

Overall, photosynthesis is a key process for plant growth and survival. For proper photosynthesis, plants depend on the right spectrum and intensity of light. In our range you will find both full-spectrum lights for the entire life of plants and many supplementary lights.

The most suitable lamps for plants

In the past, high-pressure sodium (HPS) lamps were considered the best choice for plant lighting. However, with the advent of new technologies such as fluorescent tubes, ceramic metal halide (CMH) and LED lighting, this has changed. The exception is grow rooms that get cold easily and where the heat emitted by HPS and MH lamps is desirable.

For smaller projects, such as lighting cuttings and seedlings, fluorescent tubes are still a good choice. These fixtures are relatively inexpensive. They are also quite energy efficient and have a longer lifespan than traditional discharge lamps.

CMH technology still stands the test of time. This technology is more efficient than HPS lamps and also has a wider spectrum of light that is useful for plants. CMH lamps have a longer lifespan and are less prone to overheating than HPS lamps. That is why CMH lamps are still very popular in commercial agriculture.

However, in recent years, the demand for LED lights has been growing rapidly . LEDs are becoming increasingly cheaper and have many advantages for plant lighting. These diodes are very energy efficient and have a long lifespan. LED lighting also has adjustable intensity and spectrum, which means that it can be tailored to the needs of specific plants. In addition, LEDs are much safer than HPS lamps because they do not emit as much heat, thereby saving on ventilation costs.

The biggest potential for the future lies in supplementing the spectrum with small, specialized lights. For example, UV light can increase resins and essential oils in herbs and also improve their growth. There are many different types of UV light that can be used for plant lighting and several other parts of the spectrum are promising for supplementation, such as far red.
