This chart shows how the intensity of light, the quality of the spectrum and the amount of time the lights are on, can affect different aspects of plant growth.
Intensity mainly affects the overall yield of your crop
The quality of the spectrum mainly affects the quality of the plants’ structure, tastes and/or smells
The Photoperiod (the amount of time the plants are exposed to light) mainly affects when the plants begin their flowering/ reproductive process
As you can see from the chart above, intensity, spectrum and photoperiod also have affect all aspects of growing. As an indoor grower you must consider all these lighting aspects to be a successful grower.
