Is growing plants in artificial light possible?

   Plants can grow in artificial light, but the power of artificial light is not as strong as sunlight, and its red and blue light is weaker than that of sunlight. LED lights, which are especially used in indoor grow rooms, reduce the difference between artificial light and sunlight, and can help plants grow better. Plants have an extraordinary power - the process of photosynthesis - that allows them to make their food from starch. All you need is carbon dioxide and some water. To support these processes, the plant needs some energy that it gets from sunlight. Unfortunately, the sun does not shine completely throughout the year all over the planet, when at the poles in countries such as Iceland and Finland in the north, or in Antarctica in the south, the presence of the sun decreases to only 8 hours per day. Besides seasonal changes, cities pose a problem for houseplants, as tall buildings and skyscrapers can block dwellings from sunlight. So, we have to turn on the lights!   What do p
