LED lighting in the greenhouse

LED in agriculture and horticulture

In agriculture and horticulture it is increasingly common to use LED lighting. We 'explain' a number of reasons in this article.

Light efficiency

The most important thing is that a plant responds well to the light it receives. Reacting means the extent to which the process of photosynthesis is activated. Excellent photosynthesis takes place under the sodium lamps that have been widely used so far. Unfortunately, these lamps consume huge amounts of energy, which makes sodium lamps very inefficient. LED grow lights, on the other hand, provide a lot of usable light for the plants with relatively low energy consumption. With LED, only the light that is actually absorbed by the plant is emitted. Red light (in the light spectrum from 600 nanometers to about 680 nanometers) together with blue light causes the plant or flower to bloom. It is a direct stimulus of the photons necessary for the flowering of the crop. For growing fruit and vegetables, this means a higher yield with the use of only 50% of the energy. This combination makes LED lighting for greenhouse complexes attractive.

Less heat

Well, a much-discussed topic, but no less important for that. LED lighting reaches peak temperatures of max. 26 to 27°C compared to the more than 300°C used by current sodium lamps. As the owner of a greenhouse, you know that greenhouse horticulture requires cooling. In some cases, the 'residual heat' is reused after removal, but usually the heat is a waste product that is considered lost in the breeding process. You can compare that to turning up the thermostat while you open the windows. So a shame! Excess heat also causes a crop to use more water and nutrients. In summary, we can say that if you produce less heat, there is also less waste. All easy to create with an LED greenhouse. Less heat also reduces the risk of fire.

Healthier crops?

There have been a number of studies by TU Delft, among others, which show that LED growth lighting ensures better growth and flowering. In tomatoes, for example, more vitamin C was found after a trial cultivation with LED than in a cultivation with conventional lighting. The white light and UV light in some LED lamps also ensure that fungi are less likely to develop in the crops. Will this development also make our food healthier in the future? That has not yet been directly demonstrated, but we think it will not be long before this will happen. After all, LED lighting for horticulture and greenhouse construction is still in its infancy and the possibilities are endless.
