Due to the severe global climate change, it directly affects the productivity and quality of crops, causing the agricultural economic losses to become more and more serious. People began to pay attention to the development of indoor planting in the "plant lighting factory". The LED grow light can promote the differentiation of multiple side branches and buds during the growth of plants, accelerate the growth of roots, stems and leaves, and shorten the growth cycle. It can be seen that LED grow lights are particularly suitable for artificial light-controlled plant cultivation environments, but what can be done indoors for LED grow lights to achieve excellent planting effects?
1. Install evenly distributed
Measure the floor area. Multiply the length by the width to get the square meters of the planting area. You can make the right choice based on how much power to provide per square meter, that is, how many LED grow lights are installed per square meter. In this way, each lamp can be evenly distributed, so that the outer edge will receive strong light, so that the light will be more uniform, and the growth of plants will be more effective.
2. Illumination distance
The lighting distance of LED grow lights is very important. You should adjust the points for different plants at different stages, and you must also unify the distance to make the light even more uniform. If the distance is not well controlled, it may harm the growth of plants. The general recommendation is that the germination stage distance: 60 cm, the seedling stage distance: 75 cm, the growth stage distance: 45 cm, and the flowering stage distance: 30 cm.
3. Lighting time
The lighting time of LED grow lights is mainly determined by plants, which are divided into positive plants and negative plants. Positive plants are more light-loving, and the lighting time can be longer when supplementing the light, usually 18/6 (on/off) or 20/4 (on/off). For negative plants, the lighting time is normal, usually 12/12 (on/off).
4. Dimming level
The dimming of LED grow lights can make plants grow better at each stage, the general germination rate: 30%; seedlings: 50%-75%; growth: 75%-100%; flowering: 100%. Give plants the best growth status.
5. Humidity, temperature
Photosynthesis and transpiration rate are directly affected by temperature, humidity and airflow. Find the best temperature and humidity for your plants between 75*-85*F and 50%-70% humidity, and have sufficient airflow to replenish carbon dioxide.
Indoor planting advantages of LED grow lights
1. Energy saving and environmental protection
LED grow lights are made of compounds such as crops, arsenic, phosphorus, and nitrogen. They do not contain mercury and other heavy metals inside, which will not cause pollution and danger. The sodium lamp is generally composed of mercury, sodium, xenon arc tube wick, glass bulb, getter lamp holder and other components. Once the lamp is damaged, mercury and other harmful substances will cause danger and harm to people. Relatively speaking, LED grow lamps are safer Environmental friendly.
2. Low heat radiation to avoid "high temperature damage" of plants
"High temperature damage" is also called "heat damage", which can cause plant protein deterioration, biofilm structure damage, metabolic disorders in the body, and leaf burns that can cause damage to plants. However, as a cold light source, LED grow lights will generate less heat, so there is no need to worry about harming your plants.
3. Abundant wavelength types and good fill light effect
Light is an important factor for plant growth. LED grow lights can emit monochromatic light with narrow light waves, such as red, green, blue, orange, etc., and these monochromatic lights can be used in combination. For example, LED light sources with mixed wavelengths can promote The growth and development of seedlings and roots of lettuce, basil, etc., shorten the flowering and fruiting cycle of plants, and increase the accumulation of sugar and starch in sugar beet; different ratios of red and blue spectrum can meet the requirements of different stages of plant growth, coloring, flowering, and fruiting.
Now LED grow lights are widely used in indoor planting. And the planting effect is also very good, just to make up for the lack of sunlight or the impact of the climate and region, LED grow light with its advantages to solve this problem, so that growers can plant crops more assured.
