Photosynthetically Active Radiation-PAR And Grow Light
    Around the world, thousands of homes have hydroponic gardens that utilize all types of lights to help 
many different varieties of plants to grow properly. Herifi providing people with hydroponics combo kits 
that include the types of grow lights needed for success.
   Why these lights work well? These are something named PAR matter importantly
   PAR, Reference value for the plant light compensation point and saturation point  between a third and 
half of the sum is the best, cause it is the fill light.bwith PAR can according to specific environment 
conditions. In natural sunlight PAR energy accounts for about 45%, of which 90-95% can be absorbed 
by plants.
     LED lights are a recent advancement in light bulb technology, to help grow green life by generating 
an electromagnetic spectrum that is ideal for photosynthesis to occur.three feet above the plants and 
can run 24/7 or just 18 hours a day.The emitted PAR will do help a lot your plants growth from budding
to flowering,There are many recommendations for the different type of light emitted from LEDs.  For 
example, twelve 660nm red LEDs, six 612 nm orange and a single 470 blue is generally recommended 
for hydroponic gardens.In a word, As light supplement,PAR of led grow light can be controlled which at 
any time of day can enhance the light so that always helps the plants for photosynthesis.Especially in the 
winter months, can extend the effective illumination time. Just take one of the series of Herifi made BS001 
as a example,50cm hanging height with 60 degree flat lenses can reach PAR768,it almost twice rates of 
natural sunlight can provide.
       The full spectrum of Herifi Led grow lights can cover from 400nm to700nm, which is not like red and 
blue led grow light. It can give you better growth and abundant harvests. You do not need other lights 
and just use one Full Spectrum Led Grow light, which can cover from the seed to the bloom. According to 
the test, the wavelength of the light can be well suitable for the growth of indoor plants and bloom. The 
bloom would grow worse and worse if there was no sufficient sunshine orlight. But through the spectrum
of led grow lights, the growth of plants can be promoted as well, which will improve the quality of the 
blooms and increase the yield.
