Get Full Spectrum LED Grow Lights for Sale and Watch Plants Blossom Plants depend on photosynthesis for growth and this in turn depends on sunlight. The Sun emits light ranging in wavelength from ultraviolet with the shortest wavelength at about 280 nanometers to infrared with a wavelength of about 700 nanometers. This is known as full spectrum and plants benefit when exposed to Sunlight since the process of photosynthesis needs indigo, violet, some infrared, red and orange colors to grow properly. Growers using hydroponics under controlled conditions make use of artificial full spectrum or part spectrum lighting concentrated in these ranges to promote growth and obtain better yields.
The most common light sources are low pressure sodium vapor lamps, mercury halide and halogen. However, these emit light with limited spectra with sodium vapor emitting yellow light and mercury lights emitting blue-green light. Most of the energy is lost and only a small part is used. This means lower productivity and higher energy costs. The better alternative is to get full spectrum LED grow lights for sale from quality manufacturers. Such selected LEDs emit full spectrum light in the correct balance, nearly mimicking Sunlight. LED lamps consume less power, run cooler and have a life of about 100000 hours depending on the control circuitry. They also have a flatter light spread and a directional beam, avoiding the use of reflectors and wastage of light. About 400 to 800 low cost 3W full spectrum LEDs can be
arranged in a flat panel to give uniform light output over an area of 3 meters x 3 meters, with the lumen output at 600 watt power consumption being the same as the output of other lamps.
Generally, specific full spectrum LEDs used for Marijuana growing have spectral range of 390 to 700 nm, even ultraviolet and infrared in minor amounts to promote best photosynthesis activity and leaf growth. If growers wish to promote leaf growth all they have to do is adjust light to the appropriate wavelength of around 600 to 660 nanometers and keep the lights on for 16 hours.
