An important concept when talking about the light spectrum is this. If a plant is green it'll reflect large amounts of green light. If a plant is red it'll reflect large amounts of red light. The other spectrums of light will be absorbed at a higher rate compared to the color of the plant. This is why as light intensity increases, plants will often turn bright red to protect against heavy red and blue light and intense par output.

Throughout this article, we will look at some of the ingredients of liquid CO2 and break down what they do.

It protects the plant from increased light levels. This means that the brighter the light the more red of a plant you'll grow.
