Despite apparently looking a little more expensive, the return of LED comes as the best grow lights for cannabis, without a doubt, in the durability and economy they generate. ย Because it does not emit heat in the light beam, LED technology can be used in lighting projects. It is for outdoor areas such as decks and gardens.
ย 
If you already knew about LED technology, you already knew all this. What you may not know, but we tell you, is that LED can also help in growing plants!
Why LED is considered best grow lights for cannabis?
The efficiency of LED light for growing plants has already been proven by NASA. In 2012, a group of biologists at NASA's Space Science Laboratory, in the United States, compared the reaction of vegetables exposed to fluorescent and LED lamps to test the best ways to store astronauts' food on long missions.
In doing so, they found that LED lights are ideal for space missions as well as best grow lights for cannabisย where Earth's food replenishment is limited. But the use of LEDs for growing food is not just another world.
Night irrigation solution with LEDs
The reasons for this are simple. Firstly, as we've already mentioned it that because LEDs don't heat up. Its heat is dissipated into the air through an outlet on the base, which ensures that the lamp stays cool and lasts for a long time. Thus, lighting your garden with LED lamps, you ensure that your plants will not suffer from the heat and you can increase their lifespan as well.
Furthermore, the color and intensity of the lamps are adjustable. This allows using LEDs specially adapted to plants only with the colors they absorb during their life cycle, which avoids wasting colors and energy.
Just remember the biology classes; plants are green because their leaves absorb all colors but green and end up reflecting light in that color. In other words, it is not necessary to illuminate them with the best grow lights for cannabisย that emit green light, because it will not help in the plant's photosynthesis process.
What is the best color of grow lights for cannabis and for plants?
The colors that best communicate with the photosynthesis of plants are blue and red, which are arranged in a 60ยบ harmony with green in the color circle.
However, red lights can damage plant growth, while blue ones stimulate the leaves to open their stomata, part of the plant's special cells, which allows carbon dioxide to enter, that is, it facilitates photosynthesis.
Therefore, blue is the best color of best grow lights for cannabisย for you to grow plants in your home. Now that you know why LEDs are the best choice for your garden, you may be wondering what options are on the market. Access and check out the options for lamps, luminaires and LED strips available.
What triggers the flowering mechanism?
The question of what triggers the flowering mechanism in plants is rather complex and does not yet have a complete answer.ย Getting closer to the truth allows the knowledge of the fundamental processes by which the plant blooms.ย
ย
The key point is the influence of triggers that cause a sequential chain of reactions at the genetic and physiological level. As a result, there is a morphological change in the apical shoots of the plant, which leads to flowering thatโs why the best grow lights for cannabis and other plants is essential.
The main trigger for triggering changes towards flowering is a light effect called photo periods.ย It is understood as a complex mechanism of the plant's reaction to the received light signals of a certain duration and intensity.ย The specificity of this phenomenon lies in the fact that plants react differently to light than humans or animals.
What are the spectra of light perceived by plants?
Light energy captured by plants serves as the basis for the synthesis of carbohydrates.ย With a relatively equal wavelength for the synthesis of carbohydrates, control over the processes occurs in four main spectra of light, to which plants react intensively:
- Ultraviolet 340-400 nm.
- Blue color 400-500 nm.
- Red color 600-700 nm.
- Infrared range 700-800nm.
Why various colors are necessary for plants?
To choose the best grow lights for cannabisย we have to understand this scheme. The colors of the main range are closely adjacent to each other, so their values โโcannot be clearly distinguished due to overlapping.ย In order to capture waves of different wavelengths, the plant uses various light-absorbing pigments:
- Crypto chromes (blue and ultraviolet);
- Phyto chromes (red spectrum);
- Photo tropins (blue and UV).
The essence of the influence of pigments lies in their function of "switches", providing a transition to one or another function for a stable course of biochemical processes in plants.
What is flowering?
Plants are also highly sensitive to light intensity, which appears as a shift between different frequencies.ย This occurs most often at sunrise, and the opposite process occurs at sunset. So be careful while choosing the best grow lights for cannabis.
The relationship of plant responses with respect to the time of day when the change of daily events occurs is also noted.ย As a result of a favorable set of circumstances, a specific reaction occurs, called flowering.
What are plant growth cycles?
Light has a decisive influence on the basic natural (circadian) rhythms of all living organisms, including plants.ย All these events, as a rule, fit into a certain 24-hour period of time.
The lack of illumination leads to a period of rest, when it is unprofitable to synthesize the chemical elements necessary for the capture of light energy by plants.ย Light determines the periods of activity not only by its quantity, but also by the quality to which plants are very sensitive.
The fundamental environmental factors including the best grow lights for cannabis, which include the season and the composition of the air, affect the perception of plants through triggers and are measured by pigments that control the harmonious course of vital processes.
How light affects the functioning of all organisms?
Light regulates survival, determines the pace of functioning of all organisms.ย Plants can grow even in pure red, developing quite fully.ย Expression of 660 nm red and 730 nm infrared illumination, the optimal ratio of the amount of light energy that allows the plant to determine the length of the day and night.
Before the old growth process on the surface, the seed grows underground in the direction in which there is redder than infrared color.ย Only then do seed a crack open and shoots appear on the surface of the earth. Due to these always best grow lights for cannabis is selected.
Plant growth process depending on Best grow lights for cannabis light
ย The plant forms leaves and directs them towards the nearest blue light source.ย Not having enough blue and blue light causes it to continue to grow like a root and is slow to appear above the ground.ย In this case, new leaves are not formed, as if the plant were completely hidden from the sun.
If the sunlight is bright and open, the plant tends to grow squat and small in size. Otherwise, when the plant is under the influence of 730 nm light, it grows long and elongated.ย
