You can check out the answer yourself , by a simple experiment. Plant some seeds in a pot.Wrap it with red Cellophane paper. After some days, you will see that only few plants are grown; but those are tall.
Red color of light
The photosynthesis pathway has phytochrome systems which response to red light.
RED do not try green it will not turn out as well
what red light does to green bean plants
The plants exposed to red light will likely grow better. Red light is more essential for the process of photosynthesis, which is crucial for plant growth. Green light is reflected rather than absorbed by plants, so it may not support growth as effectively.
To effectively use a red grow light to enhance plant growth, position the light about 6-12 inches above the plants for 12-16 hours a day. Ensure the light covers all plants evenly and adjust the height as they grow. Red light promotes flowering and fruiting, so use it during the plant's flowering stage for best results.
Natural sunlight.
If you use blue light in the day and red light at night it should grow twice as fast but, I would use red.
Plants are green because the reflect green light. They do not use green light, they use red light to make food. Some plastic mulches are red to reflect red light onto plants to make them grow more.
Red and blue light is absorbed from the Sun. Green light is reflected off the plant.
Plants require a full spectrum of light for optimal growth, including red and blue wavelengths. Yellow light is less effective for photosynthesis compared to red and blue light, so plants may not grow as well under predominantly yellow light. However, some plants can still survive and grow to some extent under yellow light, but they may exhibit elongation or other signs of stress due to the lack of optimal light spectrum.
Yes, plants can grow in LED light. LED lights provide the necessary spectrum of light for photosynthesis, allowing plants to grow and thrive.
