Red Light for growing cannabis

Red light is the most effective spectrum light that encourages photosynthesis. This is because it is highly absorbed by the chlorophyll pigments. Its wavelength ranges from 620 to 750 nm. This light is essential during the flowering stage of the marijuana plants. Adding red light promotes budding and flowering. Many marijuana growers switch to strong red lights with more intensity once their plant has reached the flowering or budding stage. When red light paired with blue light can balance out any overstretching or disfigured elongation of stems. Red light and blue light together produce the best response from marijuana plants.

Blue light for growing cannabis

The blue light spectrum is very important for the growth of cannabis plants. It is mainly responsible for improving plant quality.During the vegetative phase of growing cannabis, you should plant as many leaves as possible. Blue grow light color wavelengths are 450 to 490 nm. Indoor growers use 5 or 8 bar lighting fixtures, CFLs (compact fluorescent lamps), or metal halide bulbs with a blue light band. They use these for the first few weeks to achieve the request goals. When cannabis plants are grown outdoors, the angle of the sun in spring allows the season's abundant blue light energy to penetrate the leaves. Thus, this blue light signals plants to grow healthy, large leaves and become strong. Plants lacking blue light often turn yellow or pale, and are weak and drooping. Blue light is essential for proper root and stem growth in seedlings and seedlings in the vegetative stage.

Green light for growing cannabis

It is suggested that the color of green LED grow lights has little to do with photosynthesis, but it still has a certain impact on the growth of plants. Green wavelengths are considered less important than chlorophyll absorption in the blue or red spectrum. However, green light can still play a role in different stages of cannabis plant growth. The wavelength range is between 495 and 570 nm. Cannabis plants can absorb very little green light energy. However, small amounts of green light have been reported to affect growth. Many growers may believe that a green light is unnecessary for successful growth. However, if you want to grow cannabis with lights that have the full spectrum, a small amount of green light energy can be useful for you.

UV light for growing cannabis

UV light or UV rays with wavelengths between 10 and 400 nm are known to be harmful to human skin. Large amounts of UV rays can also harm plants. It is invisible to the naked eye and is at the lowest end of the spectrum. However, just because it's invisible, doesn't mean it's useless for plants. Small amounts of UV light are beneficial for the aroma, flavor, potency and growth of the cannabis plant.

The researchers suggested that increased UV exposure could increase THC levels. Thus, making the buds more efficient. When you look at where the world's most potent marijuana comes from, there is fascinating real-world evidence. Lebanon's Beira Valley and Morocco's Rif Mountains have some of the most potent cannabis in the world. However, they are all located at high altitudes, which means more exposure to UV rays. So, we can say that adding some UV light color might be beneficial to your cannabis plant.

Conclusion

There are many grow lights on the market, each with their pros and cons. Many lamps provide different colors of light, called light temperatures. If you are a grower, you will need to do proper research while lighting your cannabis plants. As you can read in this article, different spectrum have different effects on the growth of cannabis. You can use the light for all types of indoor growing. Any of these three artificial light sources can be used for indoor marijuana cultivation. They are LED (Light Emitting Diode), CFL (Compact Fluorescent Lamp) and HID (High Intensity Discharge Lamp). Too many lights can damage your cannabis plants as well as too little light. Therefore, you must research how to set up your grow lights for great indoor harvests.
