How Does LED Lighting Affect Plants?


With the warm weather finally here, the gardeners among us have been starting to roll up their sleeves and get to work with their plants. Maintaining a traditional garden is a fun pastime that can result in beautiful flowers and delicious fruits and vegetables. However, many people go beyond the traditional garden setting and experiment with different ways of growing plants. One of these methods includes using LED lights to grow plants. Is this a good idea? Or does it end up harming the crop that you were trying to help thrive? Read on to find out the answer!


Having an indoor crop can be a good idea, but it will take a certain technique to get right. Many greenhouses have started using LED lights to assist with growing plant life, considering it allows you to elongate the growing season. You also have the ability to continue your garden well into the winter months. The initial cost of LED lights is higher than if you were just using regular HPS or MH lights. However, LED lights do end up being more cost-efficient in the long run. LED lights are much more energy efficient than legacy HPS lights, which are also commonly used in greenhouses and indoor gardens. This means that the overall electricity bill will be drastically reduced. Another reason that LED lights help save money is that they produce less heat than other types of lighting. The air conditioning will not need to be turned up quite as high, and it will still be a comfortable work environment.  


LEDs will not only benefit many plant types, but these lights can also contribute to a healthier work environment for you! LEDs will reduce the need for plant hormones to assist with their growth. This will result in fewer pesticides needing to be used on the plants. Pesticides contain a vast number of chemicals, and so less exposure to these are definitely an improvement. As well, seeing as less heat is being produced by LEDs, there will be a corresponding reduction in water evaporation. As a result, less fertilizer will be required for the plants. Fertilizer also contains a variety of chemicals, which can be harmful to people’s health. If the gardeners are being exposed to less harmful materials, it will already overall be more beneficial to make the switch over to LED lights.


Even though a great deal of research has been performed as to the effectiveness of using LEDs on plants instead of conventional lights, this is not conclusive evidence for all plant types. Many plant species have not been experimented with using LEDs, and so it is difficult whether to say they would flourish or not. Different plant species will most likely not react to LED light in the same way as another type would. If you are wondering about whether a certain type of plant would do well if you used LEDs for your indoor garden or greenhouse, try speaking to a local garden center or an expert.
