Definition - What does lighting system mean?

In gardening, the lighting system refers to an artificial light source which is designed to replicate plant growth and development. Lighting systems are normally designed to produce a light which is suited to the process of photosynthesis. Grow lights can be used for a variety of plants, including salad greens, herbs, vegetable crops, orchids, houseplants and even some types of fruits.

Without a proper lighting system, indoor plants may not grow properly. The lighting system triggers the process of photosynthesis, whereby the plant converts light energy into carbohydrates that will help the plant flourish and flower. Additionally, the plant captures light energy from the lighting system to produce high-energy electrons.

Most lighting systems include yellow and red lights that encourage flowering in plants. In rarer instances, greenhouse vegetables and plants thrive best under fluorescent high blue and incandescent bulbs. Some growers also add high pressure sodium bulbs to their lighting systems in order to provide a more intense light source to their plants.

Lighting systems have been shown to trigger phototropism in some plants, whereby the leaves and stems lean towards the light source. This is especially noticeable with blue light sources.
