LED Grow Light Technologies

As the seasons change there are many things that affect plants and their growing cycles with the main factors being light timing and color of light.

The timing of light is affected by the rotation of the earth on its axis over the year, which happens to be a constant event. As the earth rotates it changes the seasons by increasing or decreasing the time that the sun is shining on plants in different hemispheres. Some plants are dramatically affected and built to respond to longer hours of light or a reduction in light.

Light color also affects the performance and sensitivity of plants in different cycles as well. As the earth rotates it also has an effect on the color of the light or what is known as spectra of light. All sunlight passes through the earth’s atmosphere and the angle at which is passes through the different layers of atmosphere affect the spectra that reach the surface. For example, during spring the sun shines at an angle which produces a more blue light, although to the human eye it is not that noticeable. With this increase in blue light the vegetative growth flourishes. The same affect is true with the fall or autumn when the earth rotates away from the sun and this fall angle of sunlight produces a more red color of light. During this time plants are triggered to produce flowers and subsequent fruits and seeds before dormancy or death. The red color of light during fall is a major factor in flower and fruiting cycles of plants.

For the average grower these seasonal factors are just a normal part of life and if you grow outdoors the sun is all you need, but if you are in a greenhouse or indoors things are different now. Indoor growers and greenhouse growers alike can now affect their gardens with LED grow lights that provide very specific colors of light such as red or blue without adding hardly any heat or power costs. Although new 3w LED grow lights can be used alone without other light, the newest invention in LED technology is called Spectra Boost LEDs and only consume as little as 7 watts of power but pack a huge punch of targeted light. Adding blue Spectra Boost to any greenhouse during winter or fall can boost vegetative growth and the Red Spectra Boost LEDs can provide better flowering and fruiting plants during winter as well.

Any indoor grower using traditional grow lights such as metal halide or high pressure sodium are able to supplement their gardens with colors that are low in their lights such as blue in HPS or red in MH. The latest field tests show an increase in flower sites and overall yields with these new 600W LED grow lights versus traditional lights alone.

Now it is possible for growers everywhere to use the reaction of plants to the suns rotation to affect their gardens in ways never before seen with new LED grow light technologies.
