But with the legalization of cannabis, people who grow cannabis indoors now choose to use 600w LED grow lights to fill the light, but pay attention to the effect of LED grow lights. We can use them together to make the effect better.
1. Improve light utilization
Wall latex paint
If you choose to use latex paint, first of all the wall area should be very smooth. Otherwise, the reflectivity will be significantly reduced. The latex paint chooses pure white instead of bright white, and the surface must be painted correctly. Latex paint is a good and cheap solution. Its reflectivity is over 85%, which makes it an efficient choice.
plastic film
Plastic film is a polymer that is black on one side and white on the other. They can reflect nearly 95% of the illuminating light, but be aware that plastic films will generate a lot of heat, and use HVAC systems to remove the heat.
2. Fill light distance
For seedlings, 600wLED grow lights should be installed between 24-36 inches above the plant canopy. The seedlings are very sensitive and this distance will keep them away from the effects of heat and high light intensity. After 2-3 weeks, once the roots have grown and started to sprout, you can move the light closer.
During the growth period, the 600wLED growth light should be installed at a distance of 12-24 inches from the top of the canopy during the growth phase of the plant. More light is needed for photosynthesis at this stage, so the light source should be close to the plant.
As plants enter the flowering stage, their demand for strong light will further increase. The top leaves of the canopy should be kept at the same distance from the light source during the growth stage of the plant to produce flowers, and the light intensity should be increased as previously described.
3. Fill light time
Pay attention to the fill light time when filling light. The lighting time of plants depends on the characteristics of the plants. Cannabis is a light-loving plant. It must take longer to fill up the light, but you should also pay attention to setting aside a certain amount of time for the cannabis to work and rest. Follow the growth law of the plant itself, so that it still maintains normal growth and metabolism.
The physiological process of effectively growing cannabis indoors, familiar with the basic physiological principles of cannabis, there are three main processes, they are as follows:
Photosynthesis converts water in plants or soil and carbon dioxide in the atmosphere into glucose, which is the main energy source. The process of photosynthesis only occurs in chloroplasts, which are tiny subcellular structures contained in leaves and green stem cells. Enhanced photosynthesis leads to faster plant development and higher yields. The key parameters for effective photosynthesis are light characteristics, such as brightness, photon flux, and wavelength. The normal atmospheric concentration of carbon dioxide is about 400 ppm, and the optimal carbon dioxide concentration range for growing hemp is 1200 to 1500 ppm. At the proposed carbon dioxide concentration, photosynthesis peaks at temperatures between 85 and 95 degrees Fahrenheit. It should be noted that many enzymes involved in the photosynthesis process are heat-labile. They degrade at higher temperatures, which means that photosynthesis slows down at temperatures above 95 degrees Fahrenheit.
Respiration is the burning of sugar, in which energy is released and used for growth, reproduction and other life processes. In this process, plants use oxygen in the air and release carbon dioxide and water back into the atmosphere. Plants absorb oxygen through the stomata of leaves and roots.
Transpiration is the process by which water evaporates through plant leaves. Transpiration is responsible for the transfer of sugar and minerals from the roots to the canopy. This process uses approximately 90% of the water that the plant absorbs from the soil through the roots. Therefore, the transpiration rate is directly proportional to the size of the plant and its water absorption. This is why during the flowering stage, when plants develop and absorb a lot of water to increase the quality of our lovely buds, they release a lot of water, resulting in high humidity in the growth tent or growth chamber. High humidity is the perfect environment for pest development and many other problems, so it should be continuously controlled with a dehumidifier.
What are the advantages of 600wLED grow lights compared with other lights?
The spectrum covers a wide range, and it is easy to obtain monochromatic light and full optical spectrum. At present, 600wLED grow lights can cover the wavelength range of 200-950nm, and there are dozens of monochromatic LEDs. Exciting phosphors can expand the half-wave width of monochromatic light, or the composite spectrum of monochromatic light, or obtain full-spectrum white light. This provides very favorable experimental conditions for studying the light absorption of different plants, realizes the customization of the spectrum of different plants, and provides the best light formula for plants.
The spectrum of the 600wLED plant growth light can be adjusted. LED is a current-driven light source, and its brightness increases as the current increases. Therefore, adjust the output current of the power supply driving the LED to obtain the corresponding brightness. The spectrum can be adjusted by controlling the current of the LEDs of different light colors. At present, the adjustable spectrum plant lights on the market are mainly used for scientific research, and the adjustable intensity plant lights have been widely used in production.
The 600w LED grow light generates less heat and can be in close contact with plants without causing burns to plant leaves and operators. The rapid development of indoor multi-layer planting technology is mainly due to the characteristics of LED plant growth lights.
600wLED grow lights have longer life span, low light decay and high reliability. The lifespan of LED grow lights can exceed 50,000 hours. The current high-end 600w LED grow light has a warranty period of 5 years, and the light decay is still less than 10% after 36,000 hours of operation. When the fluorescent lamp works for 10,000 to 15,000 hours, the light decay is usually as high as 30%.
The 600w LED grow light has strong controllability and great potential for intelligent control. Traditional lamps, such as high-pressure sodium lamps, require more than 5 minutes from power-on to stable operation, and need to cool for about 10 minutes after power failure before restarting. The response speed of the LED plant growth lamp is very fast, and it can work normally even with 30,000 fast switching times per second.
The 600w LED grow light is safe to use and reliable in transportation. Traditional luminaires mostly use glass shells, which will inevitably be damaged by broken glass during transportation and use. The LED grow light is a solid light source with high tolerance to vibration, drop and impact, and is safe and reliable.
The 600w LED grow light can not only be made into a ceiling light to emit downward light, but also can be made into a complementary light of 360-degree light between plants. Different from the 360-degree light emission of traditional light source bulbs, the LED package generally emits light on one side at 180 degrees, which makes it easier to obtain light from a small angle. It can be used as a projector to focus light on plants, or it can be made into a panel plant light with uniform light at close range.
Due to its advantages and the legalization of cannabis in some countries, the application of LED grow lights in cannabis has developed rapidly in recent years. Plants can now be grown indoors. In the near future, 600wLED grow lights will make plant growth easier.
