For the purposes of indoor gardening, LED lights are used as a substitute for the natural light of the sun.  A grow light refers to an electric lamp, which is designed to promote plant growth by way of emitting an electromagnetic spectrum which is appropriate for photosynthesis. This light spectrum resembles the light of the sun and allows indoor growth of the plants. Since natural daylight carries a high color temperature and appears bluish in color, a color rendering index is used for getting the bluish appearance.

Different spectrums are used during different stages of growth. In the initial stages of vegetation, a blue spectrum of light is required, whereas during the later stages, red-orange spectrums are usually used. You can buy lights of different color spectrums specifically for different stages of vegetation, or you may buy a full spectrum bulb which can be used during all the stages of growth.

I’ve just discovered “The Emerald” Supper Budding light. It’s apparently the only 90W five Band Grow light.  These new LED grow lights produce a better yield per watt at a lower cost. They save 90% on electricity and 100% on landfills.  All lights are 100% recyclable and you can replace your regular light bulbs and CFL’s . Using these lights will eliminate truly toxic gases like argon and vaporized mercury from your home.

Low heat emission eliminates the need for ducting and heat exhaust fans.  The replacements for your standard bulbs and fuorescents come in any required wavelength from 2500k to 7000k depending on your lighting requirements.

Last century was a period of major scientific developments. LED was one of them. LED, or light-emitting diode, refers to an electronic light source. It was invented in Russia sometime in the 1920s by Oleg Vladimirovich Losev, who was a radio technician. Losev found out that the diodes used in radio receivers emitted light as current was passed through them. In the year 1927, the details of the first LED were published by him in a Russian journal.

In 1962, the system was introduced into America in the form of a practical electronic component.  All the early devices used to emit low-intensity red light.  However, the modern LED lights are available with visible, ultraviolet as well as infra red wavelengths and carry very high brightness.  This is perfect for growing plants indoors.
