Towards ecologically sustainable food production

When buying grow lights, the top criteria should be their ecological sustainability. The world’s increasing population needs more food. We can’t increase the cultivated land area anymore without destroying the biodiversity. The only way to keep the balance between human beings and nature is to increase the productivity per land area.

Grow lights can be beneficial even in the tropics. In hot areas, or in the summertime, the sunlight is so intense that it doesn’t give any extra boost to plants because of the saturation of photosynthesis. Instead, it’s the length of the day that matters. Near the equator, the day length is nearly 12 hours throughout the year. However, plants would benefit from a longer luminous period daily. The solution is to use grow lights.

In order to use grow lights, you need a greenhouse. That solves another problem: the climate inside the greenhouse can be made more favorable for plants. Here in Finland, where I live, we have good conditions for growing outdoors in “good” summers: reasonable temperatures, long day length, and moderate rainfall. Actually, our long temperate summer days can even give a unique “Finnish” flavor to outdoor crops, such as potatoes and oats. However, our growing season is short. We need greenhouses as well to keep our food production active. We receive a very limited amount of sunlight during winter.

Surprisingly, Finnish lighted greenhouses are producing ten times more yield per land area than non-lighted ones in sunny Spain. Food production’s ecological sustainability is determined by the consumption of land area and natural resources. In Finland growers use 20-35 liters of water to produce one kilogram of cucumbers or tomatoes – the same number is 3000 liters in Spain (Silvenius et al. 2019). The study reveals that cucumber production needs ten times less space in Finland than in Spain due to the higher productivity. In addition, fewer pesticides are needed in northern latitudes. This all underlines the fact that lighted greenhouse cultivation can be environmentally friendly. Renewable energy sources and LED lighting can make greenhouse cultivation even carbon neutral! With LED lights you can get more yield with higher quality and lower energy consumption compared to old HPS lights.

In Finland, cucumber yields can be bigger in wintertime than in summertime. When greenhouses are ventilated for cooling, the supplemented carbon dioxide escapes at the same time into the atmosphere. Greenhouses with LED grow lights need less ventilation due to their lower heat load compared to HPS lights.

When using lighting, it’s better to choose an LED over any other type because it uses less energy. It’s recommended to choose a light that weighs as less as possible. Energy-saving GROWLIGHTENGINE® is designed and manufactured in Finland and is the most ecologically sustainable grow light on the market. It weighs only 3,2 kg even though it’s a 300 W LED. Only 1 kg of aluminum is used for its assembly. GROWLIGHTENGINE®’s patented spectrum is effective for all plants and growth stages. Take a big step towards a sustainable future by investing in GROWLIGHTENGINE®! More space can be left for nature.
