How Different Light Spectrums of LED Grow Lights Affect Plant Growth

No Comments


At different stages of their growth, plants absorb different amounts of wavelengths of light. LED grow lights are smart lighting systems that have the ability to increase plant productivity while reducing the consumption of energy. They generate specific light wavelengths that optimize the growth of plants. 

Within the span of electromagnetic radiation, visible light exists in a narrow range. Almost all form of life depends on this spectral range to survive. Various light spectrums have the power to stimulate specific photosynthetic responses in plants. Photosynthesis in plants is the key process that requires light to allow plants to synthesize food from the sun, water and carbon dioxide. Plants depend on sunlight for this process and it all depends on the absorption of light by the pigments in plants. Carotenoids and chlorophylls are the major pigments in green plants and they are the working parts of plants that work as machinery to absorb light. 


For indoor growing, plants require light with wavelengths lie between 400nm and 580nm, which are quite important for the photosynthesis stage. Wavelengths between 600-700nm are important for the overall development of plants. In general, the photosensitive pigments in plants absorb light in the blue and red range, but also utilize wavelengths in the far red and UV range. Great systems that provide these wavelengths for healthy plant growth are LED grow lights, which help to boost growth in plants.

LED Grow Lights and Blue Light for Plant Growth

In plants, blue light supports the growth phase. Over the years, research shows that blue light with some mixture of red light produces higher biomass of plants. Blue light spectra range from 420-470 nm, which plants utilize in their vegetative stage of the grow cycle. This wavelength supports the movement of chloroplast, stomata opening, seedling growth regulation, and phototropic curvature while slowing down elongation growth.
Blue light supports the formation of chlorophyll, photosynthesis and ultimately raises photo morphogenetic response in plants. Dorm Grow LED grow lights produce predominantly red and blue lights, along with a careful composition of other colors at the same time and this quality makes them more effective and efficient than other grow light options. Any grower can work to maximize the biomass of plants while minimizing the consumption of energy. These lights produce the right ratio of red and blue lights necessary for the best process of growth for any particular plant.

Red LED Light for Plant Growth

The wavelength of red light ranges from 630-680 nm and supports flowering during the plant growth process. Red light is very important for photosynthesis, fruiting and flowering regulation. Once again, LEDs come with the feature of these two lights and have a positive effect on the growth outcome of plants. Red light from LEDs aligns closely with the action spectrum for the production of chlorophyll while expending less amount of energy. Red light from LEDs helps to boost overall growth of plants and prove to be a cost-effective solution for the growth of plants indoors.

Conclusive Benefits

Plant yield is best when plants use up optimal wavelength of light at the right time. LED grow lights can be useful to provide a specific recipe of light for any species of plant to flourish. They are primary grow lights that align with natural light spectrums and provide optimal wavelength for successful development and yield of plants. LEDs are cost effective and energy efficient. In smaller spaces, growers could effectively use them to maximize the yield outcome of plants growing indoors. 

This is why most growers are turning to high-tech indoor grow systems that utilize LED grow systems. If you have an indoor garden, then it is best that you transition from other grow lights to LEDs. Comprehensive research from reputable universities as well as NASA shows that these lights work well in any condition. Consider this, if NASA thinks that these lights can help space travelers to produce vegetables and fruits on other planets, we can feel confident that LED grow lights will let us produce healthy plants here on Earth.
Along with providing your plants the necessary light to boost photosynthesis, these lights are energy efficient. 

This means they cut down power consumption and allow you to save as much as 50% on power costs. They help to keep pests away from the grow area and keep the space under stable conditions. Compared to other grow lights that emit more heat, LED grow lights give off less heat and save growers from additional cooling expenses and equipment such as ballasts and heavy venting systems.
