LED Plant Grow Lights

Effects of light of various wavelengths on plants Visible light wavelength (4*10-7m----7*10-7m) Light color --------- wavelength λ (nm) --------- represents the wavelength Red-----780~630----------700 Orange--630~600----------620 Yellow--600-570----------580 Green--570~500----------550 Qing---400~470----------500 Blue---470~420----------470 Purple--420~380----------420 In order to study the color properties of light, the visible spectrum is enclosed into a circle and divided into nine regions, called color rings. The number on the color ring indicates the wavelength of the corresponding color light, the unit is nanometer, and the color in the fan shape of any two opposite positions on the color ring is called complementary color. For example, the complementary color of blue (435~480nm) is yellow (580~595nm). It has been found through research that the color light also has the following characteristics: (1) The complementary colors are mixed in a certain ratio to obtain ...

With the development of vegetable facilities in the world, the soil salinization caused by excessive use of chemical fertilizers, the decline of vegetable quality, and the soil-borne diseases caused by years of planting have become more and more serious. At the same time, more and more farmers and agricultural plants are growing. The base began to grow vegetables using the soilless culture model. Hydroponic culture of hydroponic culture is a kind of soilless cultivation. It is classified into no-substrate cultivation. The non-matrix cultivation type refers to the absence of matrix-fixed roots in the environment of plant root growth. The roots grow in nutrient solution or humid air containing nutrient solution. However, some substrates may be used during seedlings. Soilless culture of vegetables is a new type of indoor soilless cultivation method, also known as nutrient liquid culture: the core is to fix the plant roots in the planting basket and let the roots naturally grow into the p...

LED fill light has been on the market for several years, the first generation of led does not have enough advantages to compete with hid in plant fill light, but the latest design of high quality led enough to mention mh and hps fill light system.
