As with sunlight the plant might reach for the light bulb.

Artificial light vs sunlight plant growth.

Although sunlight is a primary need of garden plants sometimes grow lights provide the better option when growing the plants indoors. Sunlight is rich in red and blue hues both of which are extremely important to plant growth. Plants using only artificial light should have the tips of their leaves placed six to 12 inches from the light. Sunlight if you re starting your seeds in march or february the length and intensity of the sunlight is not going to be enough to make your seedlings grow.

Most artificial light doesn t emit as much energy in the red and blue region of the light spectrum as sunlight does. Sunlight and artificial light both have their places in. Unfortunately many artificial light sources produce more of the green and yellow wavelengths which provide very little energy for plants. Rotate the plant or place it directly under the light source.

The type of light you use depends on its purpose. There are many different types of grow lights for plants. But the light from the sun is different from a street lamp another way. Others emit red or blue light but not both.

Even if you keep your house lights on every day the light will be diffused throughout the room and the lack of intensity will make your seedling plants get leggy. Plants need energy in the form of photons to grow and there is much more energy emitted by the sun than artificial light. Technological advances in plant lighting make it possible to extend growing seasons and even grow species in zones that won t support them naturally.
