Growers and scientists use LED lights to conduct plant trials under different environmental conditions, farming models, and a wide range of spectra. The reason the trials exist is to determine who different elements of light affect plant growth, and in what part of the plant. Test trials are more or less pioneering projects that have paved the way for improvements in lighting applications


What do these trials tell us about LED grow lights in controlled environment agriculture? Well, for lack of a better answer, they teach us how to set up successful plant trials. In other words, sometimes it takes testing to help us improve the way we approach LED grow light assessments. With that in mind, here are some practical guidelines for setting up successful plant trials.

●      Control the Environment

Conducting plant trials in natural settings creates too many variables due to fluctuations in the environment. Thus, determining the outcome of the trial is difficult to verify. In controlled environment agriculture, you can set up the parameters of the environment and the lighting and maintain the conditions with consistency.

●      Adjust the Light Levels

Plants convert the energy of photons into chemical energy. This response to light allows researchers to experiment with different levels of light intensity. In a controlled setting, the response to LED panels can be measured because natural light is not affecting the outcome.

●      Experiment With Light Composition

The light spectrum is an integral component in a successful plant trial. Different spectra stimulate the growth and development of plants in various ways. This relationship between plant progression and light composition needs to be tested and documented by both agriculturalists

●      Factor in the Photoperiod

Every plant has a photoperiod or a photocycle. The cycle is the ratio of day hours to night hours that is optimal for the plant’s development. Therefore, you will need to adjust the amount of light that you expose a plant to as it moves through the cycle. Increase the intensity of the light during day hours and reduce the light during the night hours.

●      Devise Light Uniformity

If you conduct a trial on a test area, you need to set up the grow light panes to distribute the light evenly across the area. That way each plant can respond to the light equally. Light suppliers can custom-design lighting panels or other models to ensure uniformity.

●      Use Light Measurement Devices

You can control your light setup by using a measuring device. The device can help you conduct your trial with accuracy. You can measure light intensity, spectrum, and uniformity.
