Although common grow lights emit blue and red light, these lamps come in many different color combinations. Because each color has different effects on the plant. So, what color light is useful in plant growth?
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.

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.
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.
Emre Yılmaz, the founder of Lighting Portal, graduated from Atılım University Department of Electrical and Electronics Engineering in 2013, and since then has been involved in the management and product development activities of state-supported projects in the lighting industry. He completed his master's degree at Gazi University Industrial Design Engineering Department and continues his education in the doctorate program of the same department.

In indoor plant growing, artificial light is needed because there is no or insufficient sunlight. HID, HPS and LED lamps are generally used as artificial light sources. LED grow lights stand out as a new generation solution in this field and have some advantages over HID technology.
If you are researching a lighting system for your plant growth facility, you may have come across many terms that you are not familiar with. In plant production; PAR, PPF, and PPFD are the acronyms you'll come across most often. So what do these abbreviations mean?
Since the concept of LED lighting has entered our lives, we have started to learn very different terms. One of them is the "full spectrum". Some manufacturers state that their LED lighting products emit full spectrum light. So, what is full spectrum?
