Does LED grow light work?

To know whether LED grow lights are useful, we must first understand the necessity of plants to supplement light, then we must first understand the photosynthesis of plants.

Many people who grow vegetables in greenhouses have questions. Are LED grow lights really useful for vegetables?

What is photosynthesis of plants

Biological definition Photosynthesis refers to the process by which green plants (including algae) absorb light energy, synthesize carbon dioxide and water into energy-rich organic matter, and release oxygen at the same time. It mainly includes two stages: light reaction and dark reaction, involving important reaction steps such as light absorption, electron transfer, photosynthetic phosphorylation, and carbon assimilation. It is of great significance for realizing energy conversion in nature and maintaining atmospheric carbon-oxygen balance. In summary, the process by which green plants use the light energy of the sun to assimilate carbon dioxide and water to produce organic matter and release oxygen is called photosynthesis.

Why do plants need light?

Let’s talk about plant growth factors

1.Light: Everything grows by the sun, so the strength of light has a great influence on the growth of plants. Some plants like positive and some like negative.

2. Water: Almost all living things in the world cannot do without water. Without water, they cannot grow and reproduce and can only die.

3. Temperature: The temperature directly affects the growth and dormancy of plants, too high or too low can affect the death of some plants.

4. Nutrients: Sufficient nutrients can make plants grow vigorously, on the contrary dwarf plants are weak.

5.Soil: Acidity or alkalinity is very crucial to the choice of plants, and the quality of soil texture is the main basis for plant growth.

6.Air: Air is the main place for plant gas exchange, and the process of oxygen and carbon dioxide exchange is carried out.

It can be seen that light is essential, and light also has a great influence on the development of plants. For plants to bloom more and produce more fruit, first of all, there must be more flower buds, and the number of flower buds is directly related to the intensity of light. With sunlight, plants on the earth can photosynthesize. The leaves of plants are mostly green because they contain chlorophyll. So how do we make plants photosynthesize when there is no light source? I won’t mention LED grow lights here.
