In our greenhouses we strive for the best and most sustainable cultivation. For example, light plays an important role during cultivation, influencing the growth of our orchids. To optimally stimulate the growth process of our orchids, the orchids need more light during the winter months than nature offers during the winter season. Based on a lighting plan, we determine what time the light goes on and off and how long we illuminate.
To make the use of light more sustainable and to use it more effectively, we have switched to LED lighting. But what is LED lighting and what effect does it have in our greenhouse? We tell you in this blog.
Until recently, we lighted the greenhouse with SON-T lighting, because sunlight is not always available and with this we sufficiently compensate for the shortage of light. Lighting with SON-T takes a lot of energy and during this lighting a lot of heat is released from the lamps, which is not always desirable.
What is LED?
LED stands for Light Emitting Diode: an economical lamp that uses electricity to produce light. You can recognize LED lighting by a purple or red color. In the greenhouse, an LED lamp is also known as a grow lamp, because the light is used to stimulate growth. We see this way of lighting more and more often in the horticultural sector and has a 40% better return compared to SON-T lighting and contributes to a more sustainable future.
What effect does LED lighting have in the greenhouse?
As a company, we are committed to environmentally friendly and sustainable solutions and have installed LED lamps in our greenhouses by 2022. This reduces energy consumption and ensures efficient light output, and thanks to LED lighting, hardly any heat is released. This is a big advantage because orchids like coolness during the flowering phase and we do not have to cool the greenhouse because of this.
Sustainable effects of LED lighting at a glance:
- 40% better efficiency compared to SON-T lighting
- Better temperature control because LED produces less heat
- Unlike SON-T lighting, LED lighting can be dimmed
How much LED lighting do we give the plants?
Sensors in the greenhouse determine how long the lighting should be on, so that the plants receive the same amount of light every day. Thanks to the sensors, we can see the distribution of the light on the plants.
Generating energy with CHP
Not only do we ensure sustainability in our greenhouse with LED lighting. We generate the electricity we use ourselves with CHP (Combination of Heat and Power). Electricity that is not used in the greenhouse is fed back into the grid for households and the heat that is released is used in the greenhouse to heat warmer sections. As a result, the generated energy is used optimally, both in our greenhouse and for households. Every day we supply electricity to the grid at times when there is a lot of demand, this is an amount that is sufficient to provide energy for 850 households.
