The Color Spectrum Affects Cannabis Plants
Before we discuss how the color spectrum affects your cannabis plants, let us first learn all about the color spectrum itself. Natural light may always seem white and colorless to us but that is most definitely not the case. Natural light in itself is made up of many different colors which is what you observe when you see a rainbow streak across the sky. This is called refraction and happens when light is divided or refracted into all its individual components such as in a prism.
It is an uncommon knowledge that plants actually tend to choose how they will grow depending on the spectrum of light they are exposed to. The color spectrum that is received by plants will affect them in various ways and in terms of germination and even flowering. When you are an outdoor cannabis grower, there are really not that many options for you to choose from and play with since your plants are exposed to direct sunlight. On the other hand, indoor cannabis growing gives you more freedom when it comes to manipulating the light spectrum you’d like your plants exposed to.
So, on to the big question, what is the best spectrum of light that you should choose for your cannabis plants? Read on below to find out some things to consider.
When being grown outside, these cannabis plants are given information as to what are the exact conditions in the environment around them based on the kind of sunlight that they receive. The spectrum of light or kind of light from sunlight varies from time to time especially between different seasons. On summer or spring, sunlight gives off a bluer spectrum because there are not that very many hindrances on its path to the earth’s surface.
Blue light is advisable for cannabis plants when they are in their vegetative stage. This is because blue light affects cannabis plants by making them short but bushy with big and thriving leaves.
Contrary to what happens during summer and spring, more of a yellow or red spectrum light reaches the earth when fall starts to come around. This is because the other light spectrums before red are being filtered off due to the changes in weather. When fall or winter comes around and when you expose your marijuana plants to red or yellow light, they tend to grow tall and also enhances the budding stage. This then causes the plants to flower faster than when they are exposed to bluer lights.
Relying on the weather changes may be the case for outdoor cannabis growers. But as an indoor grower, you have all the gear and power in your disposable to manipulate how your plants grow with light spectrum.
Just keep in mind that blue light makes shorter, leafier plants while yellow or red light makes for longer plants and more buds. Hence using them on the vegetative stage and the flowering stage, respectively. You do not however need to stick to one without the other. You could experiment and achieve the kind of growth you desire just by adjusting light spectrum inside the growing room. If you want to keep your plants naturally shorter and bushier, you could provide a little bit of blue light even in the flowering stage. You could also do it the other way around with red and yellow light. It’s entirely up to you!
