Plants can grow only when photosynthesis is greater than respiration. This critical point is called the light compensation point. For example, the light compensation point of tomato is 51.6μmol/s/m², then the effective radiation of photosynthesis must be greater than 51.6μmol/s/m² to work.   Lux is the intensity felt by the human eye. For plants, it is measured by the intensity of the light spectrum that is effective for photosynthesis. This is called photosynthetic effective radiation, abbreviated as PAR or PPF. There is no difference between PPF and LUX. convert. PPFD is the strength per unit area of ​​the PPF. Usually a 20w T8 tube LED can only provide about 24μmol/s/m² of PPFD at a height of 30cm from the plant. If it is used to grow tomatoes, then at least 3 lights. But tomatoes will grow upward. In practical applications, foreign greenhouses can only get PPFD of 90μmol/s/m² by using...

For LED grow lights, you need to work out how much light your plants are receiving and compare that number with the light they should be receiving. Most manufacturers provide light intensity measurements at several relevant heights above the plant. If you can’t find light intensity measurements from these manufacturers, you can buy a plant spectrum tester and measure it yourself. Unlike the plant spectrum tester, the Lux meter is very cheap, and in general these values ​​are positively correlated and can be used as a reference. Buying a light meter and measuring how much lux your plants are receiving at their current distance from the grow lights can be an important way to adjust the hanging height.   How many micromoles of light do cannabis plants need at each growth stage? Plants in the seedling stage require between 200-300 uMol/sec; Vegetative plants receiving 18 hours of light should receive...

Plants change the way they grow as they grow to get as much light as possible, as the sun moves across the sky, the plant rotates its leaves to face the sun, then drops all of its leaves at night to save energy and protect Own. The cannabis plant also has methods for measuring different spectrums. Different spectrums can change the way marijuana germinates, grows, and even blooms.   How Plants Identify Spectra Plants contain light sensors (photoreceptors) that detect and identify information about the spectrum. After the plant recognizes and receives the spectral information, it determines the growth mode that adapts to the spectrum, so as to obtain the maximum amount of light during the growth process. Some plants were barely affected by the strain response after receiving the spectrum, while others may have responded more strongly. Cannabis is one such plant that responds strongly to changes in light....

Guanke Technology is a manufacturer that focuses on the research, development and sales of cannabis plant lights. The temperature requirements of cannabis vary with the type of cannabis. The temperature for cannabis cultivation should be about 28 degrees Celsius, but should not exceed 32 degrees Celsius, nor should it below 10 degrees Celsius. The temperature difference should be prevented from rising and falling more than 10 degrees Celsius, because the temperature difference will affect the growth of plants. If the temperature exceeds 32 degrees Celsius, the buds will be fluffy and produce very little THC. If the temperature drops below 17 degrees Celsius, the plants will stop growing, the stems will turn purple, and the flower buds will grow slower and will not grow. But strangely, low temperatures actually made marijuana produce more THC.   The relative humidity should be kept between 50% and 60%. If vegetatively propagated in another...

LED grow light is an artificial light source that uses LED (Light Emitting Diode) as the illuminant to meet the lighting conditions required for plant photosynthesis. According to the type, it belongs to the third generation of plant fill light lamps! In the absence of sunlight, the luminaire can act as sunlight, allowing plants to grow and develop normally or better. This kind of lamp has the effect of strengthening roots, promoting, regulating flowering period and color, promoting fruit ripening and coloring, and improving taste and quality! When growing plants indoors, light can be a problem, especially for some plants that have a high demand for light. At this time, it is an ideal way to use plant lights to provide plants with the light energy required for photosynthesis, but many people will wonder question, are plant growth lights useful?   Compared with other similar products, LED lights cost less...

Why LED Grow Lights Are Needed to Grow Cannabis   A proper lighting system is another important factor to consider when growing cannabis plants indoors. With the invention of LED lights, these are considered the best light sources for hydroponics, allowing cannabis to produce more buds and flowers at high growth rates. Hydroponic LED grow lights are more energy efficient than standard halogen, high-pressure sodium (HPS), and fluorescent or metal halide (MH) grow lights. Unlike traditional grow lights, LED grow lights can be specially tuned to the specific spectrum required for specific growth stages. Cannabis is very sensitive to light and needs to be adjusted in intensity, color, and frequency for each stage of its growth. With the rapid development of LED technology, more and more cannabis growers are turning to indoor cannabis cultivation.   Types of Cannabis Grow Lights There are three different types of cannabis grow lights known...

How to increase the yield of cannabis that has already started blooming? Increase the light intensity As we all know, light is actually a supplement and therefore a transfer of life energy. Simply put, if plants get more light output, they produce larger buds. 3 Main Ways to Increase Light Intensity Install better cannabis grow lights. It is very important to keep cannabis grow lights as close as possible without overloading the plants. Trim your new buds so they develop horizontally in the light. Pruning while growing allows your plants to keep light, possibly close, without causing the highest leaf glare to burn. When the cannabis is surrounded by vegetation, it actively responds, trying to get taller for better lighting.   Choose a cannabis plant to grow light suitable for the flowering period during the flowering period For optimal yield, density, and bud size, high-quality cannabis LED grow lights should...

What is horticultural lighting? Traditional agriculture mainly relies on sunlight, which makes plant growth easily affected by the natural environment, but plants produced by plant lighting are not limited to the natural environment and can receive optimized light, temperature, humidity, carbon dioxide concentration, and culture medium components. Achieve high-quality crop output. The use of LED plant lighting weakens the restriction of the natural light environment on agricultural production activities. Efficient plant light control methods can promote plant growth and development, achieve the purpose of increasing production, high efficiency, high quality, disease resistance, and pollution-free, and enhance agricultural output capacity. At present, the application fields of plant lighting lamps mainly include greenhouse lighting, all artificial light plant factories, plant tissue culture, field lighting, household vegetable, flower planting, etc. The growth period of ordinary planting generally takes 70 days, the plant lamp only needs 21-25 days, and the planting time is one-third...

Can ordinary LED lights grow marijuana indoors? Cannabis is a sun-loving short-day plant, which has extremely high requirements for light. If the light intensity does not meet the requirements, it will affect its growth. “Generally, it is not recommended that users use ordinary LED lighting to grow cannabis, especially Planting in the greenhouse or in the basement, affected by the building materials, the light is weakened or even completely dark, which has a great impact on the growth of cannabis and the differentiation of flower buds, so the cannabis should be replenished in time.   Since industrial hemp has high requirements for light intensity, when choosing a fill light, pay attention to the power of the fill light. It is best to choose a high-power LED plant light, which can not only ensure light intensity but also save energy. High-power LED grow lights can be combined according to needs to...

We typically grow with HPS, HID and LED lights, and HPS lights have long been associated with high yields. But there’s a reason some of the biggest commercial growth businesses are turning to LEDs. In fact, in optimal growing environments, 600w HPS lights can produce as much as 150 to 300 grams, or 0.5 grams per watt or less. However, LEDs can produce as much as 1 to 1.5 grams per watt. So LED lights are more effective for cannabis cultivation than HPS and HID, the key is to choose good LED lights for your plants. LED grow lights are now powerful enough and full enough spectrum to be considered ideal for cannabis grow lights, your plants will grow 30% faster when you use full spectrum LED grow lights. How long does it take for cannabis to grow from seed to harvest using LED lights? Cannabis growth is divided into...
