What are PAR and PPFD in LED grow lights
One way to visualize PPFD is to imagine that the sun is “pouring” light onto plant leaves. As the sun shines light on plants, their leaves are gathering energy.
PPFD is a measurement of the amount of light (photons) that the sun “pours” onto plants over time. PPFD is an important indicator because it helps growers accurately measure the light intensity of photosynthesis in the canopy. This is also important because lights that are too close to the canopy can cause burning, bleaching, growth retardation, or discoloration.

Characteristics of LED plant lights: rich wavelength types, which coincide with the spectral range of plant light synthesis and light morphology; The width of the spectrum wave is half wide and narrow, and pure monochromatic light and composite spectrum can be combined according to needs; It can concentrate light of specific wavelengths to evenly illuminate crops; It can not only regulate crop flowering and fruiting, but also control plant height and plant nutrients; The system has less heat generation and small footprint, and can be used in multi-layer cultivation three-dimensional combination system, realizing low heat load and miniaturization of production space. Big Discount Meanwell Led Grow Light - LED 400W Single Bar smart grow light – Topline Optoelectronic , The product will supply to all over the world, such as: Madagascar, Lyon, Chile, Not long ago, Taga City, Miyagi Prefecture, Japan, publicly demonstrated the world's largest LED (light-emitting diode) artificial phototype plant factory to the media. The plant, called Miraihata covers an area of about 2,300 square meters and uses 17,500 LED lights, which can be produced throughout the year and is expected to harvest about 10,000 lettuce trees per day. Not long ago, Fujitsu also announced that after about a year of preparation, low-potassium lettuce produced in its own plant factory began to be put on the market.
