How to choose grow lights?
1. Choose high pressure sodium lamp or LED lamp?
As a new light source, LED has the characteristics of energy saving, environmental protection, long life, short response time, etc., and has obvious advantages in the field of agricultural lighting. Compared with traditional high-pressure sodium lamps, LEDs can adjust the spectrum and radiation intensity according to actual planting needs. In addition, LED is a cold light source with a relatively low heat output, which can illuminate plants at close range without burns, and has high light uniformity. For indoor three-dimensional farms, the small size of LEDs is more suitable for multi-layer shelf planting, saving space and increasing the overall planting area.
Although LED grow lights have obvious advantages, the specific plan needs to be combined with the types of crops and geographic locations to formulate a final reasonable plan. For example, in high-latitude areas, greenhouse cultivation in winter requires a certain amount of heat to maintain the ambient temperature. Then the mixed use of LED plant growth lamps and high-pressure sodium lamps is an ideal solution.
2. How to choose a spectrum
Light radiation related to plant growth can be divided into: photosynthesis with light energy, and light form formation with signal (stimulus) effect. Photomorphogenesis refers to the process of plant growth, development and differentiation under light conditions. Different wavelengths of light have different effects on plants. For example: increasing the proportion of blue light can promote the formation of tomato fruit species lycopene and flavonoids and improve tomato quality.
3. The uniformity of light
In addition to the type and spectrum of the growth lamp, there are many parameters that are also critical, such as the uniformity of light. The uniformity of light (regional uniformity, inter-plant uniformity, and crown uniformity) determines the appearance characteristics of plants and the consistency of individual plant products. For plants in artificial light environments, high yield and high quality are the core goals. Therefore, the light intensity and light quality must be evenly distributed during the light environment design process to ensure plant uniformity.e evenly distributed during the light environment design process to ensure plant uniformity.
