Talking about LED grow lights, what is the most reminiscent of them? Maybe a lamp is covered with LED diodes of different colors, of which white color diodes occupies most of the area and emits pinkish white light. Then it is equipped with a simple knob for easy adjustment of light and dark. This is the most popular full-spectrum grow light on the current market, which can provide plants with comprehensive light nutrition. Now, in 2022, the latest LED grow light technology is a combination of full-spectrum LED diode and intelligent technology: In terms of lighting technology, it has evolved from full-spectrum lamps composed of multiple colors to full-spectrum LED diode. In other words, each LED diode has the same spectrum. The light emitted from the lamp, each beam is the same. It overcomes the weakness of narrow LED band, so that the plant phototrophic absorption under the lamp will not be affected by the arrangement position of

Cannabis grows and develops differently to different spectral colors. One of the most critical factors in cannabis cultivation is light, but light has different colors, which specific wavelengths of light can be used to obtain satisfactory cannabis? According to the current research, the main role is the following. UV: The effects of UV light on cannabinoids were first presented in an academic paper by Lydon et al. 1987. Lydon and his team concluded that UVB increased floral THC concentrations. UVB has strong radiation and can easily cause damage to plants and growers. But UV light works by stressing the plant, which defends and produces more THC. Therefore, relatively mild UVA can have the same effect. Even UVA needs to control the amount of use, that is, the lighting time, to avoid damage caused by prolonged exposure. Blue light: Studies have shown that blue light also has a positive effect on the increase in THC concentration. Blue light has been shown to increase the concentration of cannabinoids, especially THC, as demonstrated in the article by Magagnini et al. 2018. This is the first article to compare the differences between LEDs and HPS in cannabis growth and flower quality. At the same time, blue light will also enhance the compactness of t

Why is it always difficult and time-consuming to make decisions when purchasing grow lights? Because many people will tell us that we need to know many factors before buying: light intensity, consistency, spectrum, professional terms such as PPF, PPE, PPFD, Wattage, etc. With so many nouns and concepts, it is easy to confuse people. In fact, to make a wise choice, you do not need to fully understand these terms. The following will simplify everything for you. You only need to do simple calculations according to the formula to get the best and most suitable product. Just focus on PPFD, don't care about PPE and PPF Many people will say that PPE means the efficiency of the lamp and PPF means the amount of light in the fixture, which is true but has no practical meaning. This is because light is what the plant can actually receive, and PPFD is the only indicator of how much light the plant canopy can receive. The PPFD value is not completely controlled by the PPF. So regarding the amount of light, we only need to focus on the PPFD value.
