How to choose the best LED grow lights27/08/2015 - 216
Led light is not only the choice of saving energy but also now Led lights market has proved its success in cultivating. Led lights emit certain wavelengths in the spectral range that helps plants absorb light emitted from the light faster than high pressure lamps, and can transform nutrients into energy through photosynthesis for tree leaf, flower and fruit.
Species and stage of development of plants
LOW LIGHT AND HIGH LIGHT CONDITIONS
Plants need full sunlight or low light conditions? Dimmable LED lights may be the way to adjust the intensity of PAR. Dimmable LED lights (Illumitex, Kind LED K5 series, Hydro Grow, Eonstar) also allow you to change the amount of light without adjusting the height of the light and allow you to mimic the light changes with the seasons that some plants require.
VEGGING OR FLOWERING
Are you growing vegetables, flowers, or both? There are LED lights designed specifically for your plants (blue spectrum lights) and LEDs for flowering (red spectrum lights). Fixed light with specific spectral brands can also be used outside the LEDs with have sufficient spectrum to provide a boost during veg and bloom. G8LED provides an extra boost of red for flowering.
RED AND BLUE LIGHTS ARE IMPORTANT
A complete cycle of lights will give your plants blue and red wavelengths necessary for good growth. Blue light mimics the light of the summer sun and stimulates the growth of leaves and red lights takes the place in autumn with short day. When combined with blue light, the wavelength of red start to stimulate flowering. You should look for lights with blue light in the 440-470nm range and red in range of 640-660.
UV AND IR
In addition to blue and red light, you might consider a light contains ultraviolet and infrared wavelengths.
UV light activates the defense mechanisms of plants, affect plant development, growth and metabolism. IR light increases flowering and accelerates stem elongation. You should choose LEDs with UV in range of 315-400nm and IR in ~730nm and up.
White LEDs adjust exactly wavelength and color temperature, provides full spectrum of white light. Make sure the colors of the LEDs are in the middle of the temperature range. 5500 K is a fairly balanced color to provide blue light necessary for growth and the red light for blooming.
In conclusion, the best light grow lights for growing indoor plants will include red and blue LEDs or a whole spectrum of white light. UV and IR can be included to enhance the physiological functions of plants, but not mandatory. Do not hesitate to contact us for further advice.
Scope of coverage
You should choose grow lights based on the area you want to cover. A small light can cover 4 sq ft, while a larger light can cover 25 sq ft. Some growers recommend you buying a larger light, because it is cheaper.
Besides the size of the lights, beam angle (or lens) is also important. A small angle (30 degrees) reduces the area covered, but provides more energy. A large angle (90 degrees) expands the lighting but reduces the energy supplied to the plant.
With these criteria, you can completely choose the best LED for your crops.
