LED grow light systems have long proven themselves a versatile, space-efficient tool in controlled environment horticulture. Everyone from the urban homeowner to the large-scale farmer is discovering this agricultural revolution.


Growing food with LED lights is easy; almost any crop will bear fruit under them. However, because every plant species is biologically different, each has unique needs. Therefore, some species may have their needs met particularly well underneath a certain type of LED light. For other species, in contrast, that same LED light for plants and natural sunlight yield similar results.


But why is this? Growfilm®, a flexible LED grow light company, digs into the science behind LED lights below, and also discusses some common plant species that are particularly successful under them.

Red Light or Blue? It’s All about the Hue

First, a little physics lesson just for background purposes:


Light, just like electricity, is a form of energy. Visible light energy takes the form of waves. The color of the light we see is directly tied to how much energy is in that particular wave. Violet light, for example, is high-energy, while red is low and blue light is somewhere in the middle.


How does this relate to plants? Plants need light that comes in red or blue; every other light color on the spectrum is fairly useless to them. Red light generally encourages fruit production in plants, as well as flowering, while blue light usually causes a plant to produce more foliage.


More traditional artificial lighting forms, such as fluorescents, only produce white light—light that is, essentially, all the colors of the spectrum at once. Commercial grow lights that are LED, however, have been engineered to produce red and blue light. That’s why flexible LED grow lights have been so successful; they give plants exactly the type of light they need to grow.

So What Plants Will Grow Well?

As stated above, LED lighting for plants can be fine-tuned to provide optimal conditions for almost any crop. It isn’t so much that some plants can’t tolerate LED lights, but that they need different types of LED lights to produce the best they can. For example, leafy crops (such as lettuce, cabbages, cannabis, and herbs) might require more blue lighting, whereas vegetable or fruit-bearing crops (such as tomatoes or strawberries) might need a bit more of a red tint. Every plant can grow well, but you need to research to determine the best LED light for that plant.
