Industrial hemp is an annual herb. In addition to its particularly important properties, it also has more uses. For example, it is a raw material for fiber products, clothing, ropes, sails, grease, paper, and medical supplies. It also has many medicinal uses. value.
With the legalization of cannabis cultivation now, factories and enterprises as well as small agricultural individuals are growing cannabis. Because of the high economic income brought by its wide range of applications, growers use LED grow lights to supplement light to shorten the cycle and improve quality and yield. How to grow hemp with LED grow lights?
First of all, we must know that if each cannabis plant is exposed to the same light, the illumination of the LED grow light must be uniform. The uniformity of LED cannabis grow light illumination can be divided into the uniformity of chip distribution, the installation height and the distance distribution between the LED grow lights.
yaorong LED grow light chip distribution
The chip distribution is based on the characteristics of the LED grow light supplement light. After the lamp bead ratio is obtained, how to intersect between the chips is calculated, and finally distributed on the plant light package and the COB panel according to a certain rule, so that each The LED cannabis plant light illuminates the main area with uniform light quality and light intensity.
Installation height and distance distribution of yaorong LED grow lights
The arrangement of the spacing between each LED grow light is mainly determined according to the light intensity. In addition, the installation height of the LED cannabis plant light must be considered. After a comprehensive calculation, the distance distribution between the LED grow lights can be obtained to ensure large-area cannabis cultivation. Uniformity of illumination.
yaorong LED grow light lamp bead distribution
The uniform distribution of LED grow light beads is to ensure that the light energy is evenly irradiated on the hemp. The lamp beads are mainly composed of red and blue lamp beads. If the positions of the lamp beads of different spectrums are not reasonably and evenly distributed, the growth state of cannabis in the irradiation area of the LED grow light will be different, and the meaning of using the LED grow light will be lost.
How to control the distribution of lamp beads in LED grow lights? First determine the number of LED grow light beads, and then determine the ratio of red and blue lamp beads according to the needs of hemp, and then install them on the lamps evenly in a dislocation. If it is a small area of light supplementation, it can ensure uniform light in the middle, if it is a large area of light supplementation, ensure that the surrounding light is even, so that the adjacent LED cannabis plant lights can be superimposed, which can just achieve the desired effect.
Physical reaction with optical equipment
The LED grow light can also realize the efficient use of light under the condition of uniform illumination. The main physical principles used are light reflection and light refraction.
The LED hemp grow light uses the reflection and refraction of light not only to make the light more uniform, but also to achieve high luminous efficiency. It mainly uses the reflector and the metal substrate used by the COB. The principle of the LED grow light reflector reflects the light emitted by the light source into a beam, increasing Local light intensity, the reflective effect of the metal substrate is also to maximize the light energy emitted by the LED grow light lamp beads to be used by plants, the reflected part is auxiliary light, it also has the role of fixing the lamp beads and heat dissipation.
yaorong LED grow lights regulate light to affect the growth of cannabis
Regulate the photoperiod
Cannabis, like humans, requires rest time. Long-term supplementation of light does not have a good effect on the growth of cannabis.
If it is not affected by people in the natural environment, then each plant adapts to the natural environment to form its own photoperiod and survives in this uncontrollable natural environment. But if it is an artificial cultivation environment with LED grow lights, we can control the photoperiod of cannabis by adjusting the spectrum of LED plant lights.
Adjust light intensity
The light intensity will affect the cell proliferation and the differentiation of seedlings, buds and roots of cannabis, and indirectly affect the growth of cannabis. Different light intensities correspond to the various stages of cannabis growth. In the early stage of growth, too much light is not required to meet the needs of germination and growth. Yes, with the growth of cannabis, the light intensity should be appropriately increased, which is very important for the healthy and neat degree of seedlings. When flowering, LED grow lighting directly affects the flowering period and fruit setting rate, and also determines the yield and quality of cannabis.
Control light quality
The quality of LED grow light is mainly the choice of lamp beads. LED grow lights generally have red light beads, blue light beads, white light beads and full-spectrum lamp beads. Numerous experiments by scientists have proved that the light needed for the growth of cannabis is red light. As with blue light, most users choose red and blue light beads, but there are not only plants that need red and blue light, so when choosing light beads, you need to customize the light beads according to the light quality required for the growth of the plant.
The above describes how to use LED grow lights to grow cannabis. You can use LED grow lights to grow cannabis plants in a better growth state. If you have any questions, please feel free to consult.
