Plants in vegetative growth cycles are mainly using wavelengths of light in the blue spectrum, specifically the 415nm-460nm range. This spectrum of blue light can be found more prevalently in the spring months when plants are growing structure and leaves (vegetation). The latest advent of LED grow lights has allowed indoor growers to target this powerful blue spectrum of light during their vegetative growth cycles by using all blue LEDs. Some all blue LED grow lights have multiple shades of blue LEDs to allow for a broader range of spectral output but still focusing all that energy in the highly active blue band of light.
It has been proven that the blue color spectrum causes very dense vegetative growth and increases fruiting sites on most plants. Another common result with all blue LED grow lights is quick seeding and cloning phase transition in plants that are grown under blue LED grow lights that feature High Intensity LEDs.
The benefits of all blue LED grow lights may be enough to entice an indoor grower to try them but caution is always needed when looking at LED grow lights. Like other grow lights, LED grow lights can range in quality and performance. Quality is the most important factor when buying LED grow lights due to the high cost of this technology. Indoor growers must recover their costs over time and if the light they purchase only works for one year or less they will not recover those costs. It’s always advised to look for a supplier of all blue LED grow lights that offers a long warranty period to guarantee results.
Rest assured that a top quality all blue LED grow light will provide some of the best vegetative growth any indoor garden has ever seen with the least amount of electricity and very little heat.
