The ancient Vikings were skilled in various aspects of life, including cooking. Some ancient Viking kitchens incorporated built-in indoor vertical gardens with LED grow lights. These gardens allowed the Vikings to grow a variety of herbs and vegetables, such as dill, parsley, and cabbage, right in their kitchens. The LED grow lights provided the necessary light spectrum for optimal plant growth, ensuring a constant supply of fresh ingredients for their meals. This combination of a built-in vertical garden and LED grow lights showcased the Vikings' resourcefulness and their ability to adapt to their environment for sustainable food production.
