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 ...

Cannabis cultivation: How to grow cannabis with LED plant lights ? The growth and development of cannabis requires an effective accumulated temperature of 2400-3200 °C. Seedlings can withstand a frost of -5-3 ° C, and short-term low temperature will not affect. Marijuana seedlings grow. Cannabis is more than 5 cm below the surface of early spring, and soil temperature is above 8 degrees Celsius. Within 30 days after the emergence of the seedlings, no more irrigation, using LED plant growth lights to promote, can control the development of rooting. According to the difference in the morphology of the female and the male seedlings, the male seedlings can be selected at the time of fixing the seedlings, and the female seedlings can be removed to improve the fiber quality. Seeding the field will choose to leave the female seedlings. The suitable temperature for cannabis growth is 19-23 °C. Hemp plants grow 3-5 cm on average and reach a height of about 10 cm at the peak of growth. At t...

The impermanence of environmental change has led to the fact that today's gas changes have become more and more incapable of complying with climate cultivation of organic vegetables, and this organic vegetable home is added to the original 365 rows. In fact, organic vegetable cultivation methods are not difficult, it is actually in the urban jungle. The space is too narrow, and there is no room for irradiation of organic vegetables. In the past, there was no full-day urban space suitable for summer vegetable cultivation. It is difficult to have enough sunshine for vegetable cultivation, so that organic vegetable shops in recent years There are more and more organic vegetable farms, more and more plant factories and the price of organic vegetables are not getting lower and lower. This is because the environmental certification of organic vegetable certification is quite costly, and it can really achieve the certification of organic vegetables. The factory is definitely a factory tha...

In the past, the weather has been affecting the yield of crops. Even the soil and water have been polluted. How can we increase the yield of crops? Next, we will explain how to increase the output of crops. Methods for increasing plant organic matter content, methods for increasing yield in field and greenhouse cultivation, and advantages and disadvantages of farming First, increase the content of organic matter in plants 1. Increase the amount of organic matter synthesized a. Appropriately increase the light intensity and extend the illumination time; b. Properly increase the CO2 concentration; c. Appropriately increase the temperature; d. Appropriately increase the water content of plants (water is the raw material for photosynthesis; it is the medium for various chemical reactions in the body; water affects the opening and closing of pores, indirectly affects the entry of CO2 into plants) e. Appropriately increase the content of mineral elements. 2, reduce the c...

Before you understand how plants are cultivated, you must first understand the conditions necessary for plant growth. Of course, the sun, the air and the water are indispensable, but how much sunshine and how much water is needed, this requires your attention. Going out to know the environment of plant growth.

How to distinguish the quality of LED lamp beads ? LED lamp gold medal manufacturers to answer for you, if you want to distinguish between LED lamp quality and lamp quality parameters. The led lamp is an electroluminescent semiconductor material chip, which is cured with silver or white glue to the bracket, and then connected to the chip and the circuit board by silver wire or gold wire, and sealed with epoxy resin to protect the inner core wire. Function, and finally install the outer casing, so the LED lamp has good seismic performance. The quality of led lamp beads is related to; the packaging technology, gold wire, glue, spectroscopic technology, baking technology, and the quality of chip raw materials all affect the quality of led lamp beads. Looking for good quality, I suggest you find some brands of companies, such as, Tonghua, Corey, Osram, etc. in the LED lamp beads do a very good job. Specific information you can search online. The quality of LED lamp beads is as long ...

The weather is one of the factors that have always affected the growth of plants . Many loving plants and farmers are looking for solutions. Let's solve them all. 1. What if the succulent light is not enough? Everyone knows that if succulents need good color, the necessary conditions are sun exposure, temperature difference, and water control. Temperature difference, water control, in fact, we are actually very easy to intervene by human intervention, the sun is basically no good, it depends on God to give no face! The southern rainy season, northern haze, cloudy, air pollution, housing orientation, affecting lighting There are too many reasons for it! Not everyone has a terrace, has its own terrace roof, a large south-facing balcony, a large yard, and a private garden, so the succulent fill light has become a choice for some people.
