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...

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 ...

The good habit of raising fish is to check the water temperature every morning and evening, to observe whether the water temperature is constant, and whether the work of the constant temperature heater and the oxygenator is normal. Observe the activity of the fish. Carefully observe whether the fish swims normally, whether the body shape and scales are abnormal, and whether the appetite is strong. If abnormalities are found, they should be analyzed and treated in time. Observe the turbidity of the water, whether there is odor, etc., in order to change the water in time. Remove dead fish in time. If the dead fish is not removed in time, it will rot quickly and deteriorate the water quality. Especially when the water is turbid, dead fish are often difficult to find, so the inspection should be meticulous. Attention should be paid to fixed lighting time, regular water changes and disease prevention, fixed feeding time and feeding amount. Next, I will talk about some of the experience of f...
