As the world population increases and metropolitan areas attract more and more people, new challenges arise for the future of citizens, including how to meet growing food needs in a sustainable and close way.

Faced with this challenge, LED promises to play a fundamental role, putting within our reach the possibility of configuring the exact light composition so that plants grow and develop their properties and characteristics to the maximum.

From this premise GROW is born, the NTE range of horticulture luminaires. A lighting system developed to condition growing crops, without providing more heat than necessary and ensuring the maximum benefit for the producer.






Since photosynthesis is the basic process that leads to the growth of a plant, light forms an essential part of it, since with the energy provided by light, the plant is able to produce its food (glucose) from the gas of carbon dioxide (CO2) and water, which are absorbed by the leaves and roots.

However, the only part of the global radiation spectrum that can be used by the plant in this process is between 400-700 nm (a total of 45% of it), a strip known as PAR light. English for Photosynthetically Active Radiation), usually indicated in micromoles (μmol).

Light properties that affect plant growth

Amount / Intensity of light

The speed of photosynthesis depends largely on the amount of light. The reaction of this process is higher as the PAR increases, in a way that even each plant species begins the process of photosynthesis at different levels of light energy, a moment known as light compensation point.

Quality of light

Light quality refers to color or wavelength. The sun emits wavelengths between 280 and 2800 nm (97% of the total spectrum distribution). They are divided into three regions: Ultraviolet (100 to 380 nm), visible light (380 to 780 nm) and infrared (700 to 3000 nm). In general, different colors have different effects on plants and therefore, it becomes essential that the light source distributes that color spectrum in an effective way in order to obtain the required results.

Light duration or photoperiod

The number of daylight hours per day directly impacts flowering. Plants can be divided into three categories based on the length of day that is required to trigger flowering: short day plants, long day plants, and neutral day plants.

Light color

Plants also have a special sensitivity to light color. Regarding the growth of plants, light is defined in terms of particles, also called photons. The photon flux density (PPFD) varies, depending on the wavelength (color spectrum of light), for example often red light sources produce more efficient light photons than blue light sources. However, each type of plant also has a varied sensitivity for different light colors, which influences different processes of its development such as height, pigmentation, etc. The key to using efficient plant light sources is therefore to find effective light combinations in order to obtain optimal production results.

LEDs (light emitting diodes) are called to play a very important role in this regard, since with LED lighting, the grow light (spectral output) can be adjusted.

This capacity is what allows the optimal “light formula” to be applied at each stage of growth of a crop and in each different type of crop, responding to the light needs of each plant. But color is only the beginning. LED also provides effective heat management, long life, high light efficiency and energy efficiency, opening up enormous opportunities for the commercial horticulture market.

Greenhouse crops that use LED lamps have a positive impact on the environment, using only 5% of the water, 3% of the space and half the time that a normal crop would need.

GROW is the outcome of the LED technology expertise of the NTE technical team, combined with an extensive research process in the field of horticulture.

Equipped with a selection of the most efficient LEDs on the market, the GROW range provides plants with the maximum photon flux density (PPFD) by distributing them in the most homogeneous way, thanks to their configuration and optics. as a result there’s an improvement in the quality of the crop, both in the nursery and indoors, as well as a reduction in the duration of the growth cycle, increasing the productivity of the plantation exponentially.

In addition, the quality of its components ensure great durability, with little need for maintenance and easy installation.
