The Effect of Light on Plant Growth
Every living thing needs energy to grow. Humans get their energy from food. Plants, on the other hand, get energy from light in a process called photosynthesis. Light initiates the growth cycle of the plant and supports its healthy development. Blue light is essential for the first stage of plant growth. In the flowering phase, red light is needed.

Without natural light or artificial light, the plant would not be able to grow, reproduce and find enough oxygen to support life. Without light, green plants would not exist in our lives.
Plants need three basic things to live; light, water and carbon dioxide. Plants use water and carbon dioxide to produce food. Plants use energy from sunlight or artificial light sources to convert carbon dioxide, soil nutrients and water into organic compounds. This process, which forms the basis of plant life, is called photosynthesis.
White light includes various colors such as red, blue, green, yellow, orange and purple. Plants absorb some colors and reflect others in order to photosynthesize. Blue light is essential for the first stage of plant growth. In the flowering phase, red light is needed.
Natural sunlight is best for plant growth. Sunlight, which provides the right balance of blue and red light that plants need, is extremely important for the growth and flowering of plants.
Artificial light sources also work similarly to sunlight. Fluorescent, incandescent, metal halide, high pressure sodium and LED lamps are artificial light sources used to support plant growth. Artificial light sources make it possible to control the growth of plants and produce faster.
The type and amount of light needed for all plants is not the same. Some plants need only a few hours of light per day, while others may need 8 hours or more per day.
Plants deprived of light tend to grow upwards, seeking light. This is the survival mechanism of plants. If the plants do not get enough light; leaves turn yellow, shrink and stems become weak. Plants that don’t get enough light eventually lose their color and die. Exposure of plants to too much light can also negatively affect plant growth.
Light is only one of the factors that affect plant growth. Climate, weather, altitude, weather and pest control also affect plant growth and production.
