Lights on plants

There is no debate that light is important to the growth of plants. But as you have learned this week, not all lights are the same. The light plants receive can vary in color, intensity and even duration. These are the three fundamentals of agricultural light science:

  • Photoperiod (How long the plants are getting light)
  • Light Quality (The color of the light being given)
  • Light Intensity (How much light the plants get)

Adjusting these three variables can do much more than just help or hinder how plants grow. They can actually affect the height, how often they bloom, when they bloom, and even the taste of the plants. The light that plants receive is a very important part of agriculture. Let’s explore these three fundamentals in depth.
