The first three questions in the proper characterization of an agronomic lighting solution
The basis for the correct characterization of an agronomic lighting solution stands on answering three questions.
Of course, in order to reach the optimal result, it's very important to also answer a lot of other questions. However the basis is in answering these three questions and the relationship between them.
1. Which spectrum do I need?
Agronomic light spectrums need to suit the plant, the growth stage and projected result. Changes in the spectrum can affect the biomass of the flower, the ability of the plant to absorb light energy, the growth rate, color, height, size of root system and more. Pay attention to this point and research it as it is critical to success.
2. Which light intensity should I provide the plant?
First, when answering this question, decide where you are measuring. What is the measuring height? Whereabouts on the plant? What is the distance from the lighting fixture?
3. How long to illuminate?
The length of illumination during a 24 hour period is highly important and will be a vital ingredient in your influence on the plant. Dark hours are no less important than light hours. To characterize our solution, we must research the maximum and minimum lighting time that can be given the plant in order to achieve the desired result.
I usually recommend that we decide on the maximum number of hours of daylight we can give. The reason for this is that if we work with the maximum, we can use lower levels of illumination which both lessens the cost of arrays and lessens heat emission from the lighting fixtures.
In many cases we choose the duration by the DLI we target. Here there is also a recommended DLI range decided by the needs of the plant and each growing stage. The intensity level that we characterized in question 2 relates to the amount of energy measured per second. DLI relates to the amount of energy per 24 hours. The multiple of the answer to question 2 by the answer to question 3 will determine the DLI and this is the link between these questions.
This is the basic idea which is worth investing in.
Beyond professionalism, the correct answers here are worth a lot of money both in the cost of a chosen solution and in maximizing production capabilities in your growing facility.
We must carry on and answer a lot more questions before we select our solution. Start your research with these three questions. Do not underestimate the importance this knowledge will bring in characterizing the correct solution.
I wish you good answers, knowledge and lots of success.
