V-HORTI LED grow light

 V-HORTI use Nichia’s Hortisolis technology.

They produce light of a special spectrum that favours plant growth and increases production.

At the same time, the emitted light is white,

does not tire the worker and makes it easier to distinguish the degree of plant development.

They have a high IP66 waterproof rating and excellent durability. They are made of anodized aluminium, so they are suitable for use in adverse environments.








Light is essential for photosynthesis, the primary energy conversion mechanism in plants. The process is driven primarily by red and blue light through chlorophyll in photosystems II and I. Three factors are important here:

  • Light intensity - measured in the number of photons a plant can use
  • Photoperiodization - which reflects the duration of the exposure.
  • Light quality - corresponding to the wavelengths of light to which the plants are exposed.


Light affects plant processes in many ways. Each process can be attributed to a specific photoreceptor that reacts to a specific range of wavelengths:
Cryptochromatic photoreceptors perceive blue and UVA light and are responsible for phototropism and photomorphogenesis.
Other photoreceptors, phytochrome, are receptors of dark red radiation (far-red)
Phytochrome, unlike cryptochrome, has 2 forms that differ in the wavelength of light they absorb.
Pr (red photochromic) absorbs red at 660nm
Pfr (dark red phytochrome) absorbs dark red at 730nm.
However, interestingly, Pr and Pfr can interconvert their molecular structure depending on the ratio of red and dark red wavelengths.

Since blue light and red light are the primary wavelengths absorbed by plant chlorophyll, purple fluorescent lamps or a combination of blue and red LEDs have traditionally been used as the most energy-efficient lighting for plant growth.
However, lighting with only two colours, blue and red, is tiring for workers and causes problems in the work environment, such as difficulty in determining the degree of growth of plants.
Recently, there has been a growing interest in lighting similar to natural sunlight to solve these problems.
However, white light, which is similar to natural sunlight, contains wavelengths that are not necessary for plant growth and are not optimally efficient relative to the energy cost of their operation

V-HORTI LEDs are designed, in addition to the red and blue spectrum, to produce infrared red and green.
The purpose of adding infrared light is to induce the shade avoidance response in plants. Plants monitor the ratio of red light to infrared light (R/FR). Infrared light is not absorbed by chlorophyll. Shaded parts of the plant recognize the higher FR to R ratio and respond by extending their stems to gain access to light. This behaviour is called the shade avoidance response.
This way, infrared light stimulates plant growth by inducing the shade avoidance response.
The purpose of adding green light is to create almost white light by combining it with blue and red, to improve working conditions and facilitate the observation of the degree of growth of plants and fruits.
