LED Plant Grow Lights

Check if the power supply is working properly and the command light is on. If not, please check if the power supply is connected correctly. Check that the power cord of the lamp is well connected to the positive and negative electrodes of the power supply and that there is any reversal. If the above problem exists, please connect it correctly. 2, LED plant growth lamp beads on the voltage requirements: The nominal 3V LED lamp beads, in fact, different colors have different current requirements, yellow requires the least current, followed by red, green, white and blue. If the current is too large, the wick will be burnt. With a 2.4V rechargeable battery, yellow is easy to burn because even if the voltage is low, the current is too large and it will burn at will. A fleshy bulb with a specific wavelength of LED can affect the flowering time, quality and duration of the flowering of the plant. LEDs of certain wavelengths can increase the number of flower buds and flowering of pla...

I always say that you only really need three thing s to be successful in this hobby, good water quality, good water flow, and good light. All of those things are pretty involved but lighting in particular gets a lot of discussion, because of the three it is the most exoensive and the thing that is going to most dramatically affect how the fish and corals in your tank will look. My goal in making this video isn't so much to give a prime to beginners, it is to illustrate just what a difference lighting can make. Corals can color up differently under different lighting systems to varying degrees, but lighting systems can also drastically affect the appearance of the same exact coral. A lot is made of what corals look like online. Are the images oversaturated? What kind of lighting was this taken under? The list of questions go on and on. What most people do not realize is that much of what that coral will look like has more to do with the lighting selection by the hobbyist than the...

Light is one of the important environmental factors in plant growth. With a reasonable light environment, plants can grow and develop healthily. A plant lamp is a type of luminaire that uses the light of the sun to simulate the light environment required for plant growth. Due to its small size, light weight, long life and adjustable light intensity, LED plant lights have become one of the important light sources for plant light environment regulation, and have obvious advantages in energy saving and plant growth. Plant tissue culture is a new technology of asexual reproduction developed in recent decades based on the theory of pluripotency of plant cells. Tissue culture of plants is also called ex vivo culture in a broad sense. It refers to the isolation of tissues, organs or cells, protoplasts, etc. from plants, which are inoculated under sterile conditions with various nutrients and phytohormones. The culture medium is cultured to obtain regenerated whole plants or to produce...

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 ...

Basil, alias orchid, hairy basil, sweet basil, nine-story tower, etc., is an annual herb of the family Corydalis. Hydroponic plants should be supplied with liquid during the cultivation process to ensure adequate nutrient supply. The liquid supply time is generally selected during the day and no liquid supply or less liquid supply at night. The number of liquid supply on sunny days is more, and there is less liquid supply in rainy days; when the temperature is high, the light is stronger, and vice versa. Usually, the liquid is supplied 2-4 times a day, and it can be grasped for 30 minutes each time. This can be adjusted at the right time with the time controller. Hydroponic plants are exemplified by pipelined hydroponic vegetable production equipment. Production management is mainly to adjust the time of supply of nutrient solution and the number of liquid supply. The liquid supply time and the number of liquid supply times of the nutrient solution are mainly determined according to th...

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. Here's how to help you savvy you choose high quality LED plant fill light products: 1, to choose high power led Planters should choose high-power LED products, and low-power LEDs are not enough to support the entire growth process of plants. High power led should be greater than 1W. The 3W series of LED products include: CreeXR-Lamp, Luxeon Dragon series. High-power LEDs usually integrate a large piece of metal at the bottom for heat dissipation. 2, choose the big brand long life led products The lifespan of hps is usually 20,000 hours, and the actual use is generally 5,000 to 10,000 hours, because the illumination of long-term sodium lamps will decrease. The lifetime of high-quality LED products is generally between 50,000 and...
