How do LED grow lights work ?
Light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Controlling plant morphogenesis through light quality regulation is an important technology in the field of facility cultivation.
Plant growth lights are more environmentally friendly and energy-saving. LED grow lights provide plants with photosynthesis, promote plant growth, shorten the time for plants to bloom and fruit, and improve production.
LED grow lights can help shorten the growth cycle of plants, because the light source of this light is mainly composed of red and blue light sources, using the most sensitive light bands for plants, the red wavelengths use 620-630nm and 640-660nm, and the blue wavelengths use 450-460nm and 460-470nm.
These light sources allow plants to produce the best photosynthesis, and the plants get the best growth state. Experiments and practical applications have shown that, in addition to supplying light to plants during the lack of light, they also allow plants to promote multiple hair growth during the growth process. The differentiation of lateral branches and buds accelerates the growth of rhizomes and leaves, accelerates the synthesis of plant carbohydrates and vitamins, and shortens the growth cycle. In modern construction, it is an indispensable product for crops.
Description of basic parameters of plant light:
Conventional installation height and lighting time of plant lamps:
According to the different responses of plants to photoperiod, plants can be divided into three types: long-day plants, short-day plants and intermediate-day plants;
①Long-day plants: In the process of plant growth and development, flower buds can only be formed when the number of light hours per day exceeds a certain limit (14-17 hours).
The longer the light time, the earlier the flowering. Such as rapeseed, spinach, radish, cabbage, sweet-scented osmanthus, etc.;
②Intermediate sunshine plants: During the process of plant growth and development, there are no strict requirements for the length of light. Such as rose, cucumber, tomato, pepper, Clivia, etc
③ Short-day plants: During the process of plant growth and development, 8-12 hours of light is required. Such as strawberries, chrysanthemums, etc.;

While there are many factors to consider when designing an overall system, terminal blocks are an optimal solution for complex electrical system connections. With a variety of color options and configurations, Premier Cable’ terminal blocks offer a range of options to meet your design challenges.
CAN-bus has been widely used in various automation control systems. For example, CAN-bus has incomparable advantages in various fields such as automotive electronics, automatic control, smart buildings, power systems, and security monitoring.
M12 encoding types are A encoding, B encoding, D encoding and X encoding. A-code, B-code and X-code are some of the earliest developed and longest-available M12 connectors. The latest M12 coding types currently under development are K coding for AC and L coding for PROFINET DC.
The three different sizes of NMEA 2000 certified DeviceNet standard cabling are "micro," "mid," and "mini."
The Premier Cable Starter Kits provide everything you need to get to create a basic NMEA 2000 network from scratch.
DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
