Grow Light Tutorial

Providing sufficient light for plant photosynthesis of indoor plants is a common problem that many indoor gardeners face. A grow light is an electric lamp, which simulates natural sunshine, and provides the appropriate light spectrum to promote plant growth and blooming. Vegetronix caries innovative innovative grow light systems for indoor potted plants.

Anyone who has played with a prism will know that white light is a spectrum composed of all of the visible colors. The goal of a grow light is to provide just the right amount of light of the appropriate light spectrum to the plant. When evaluating a grow light the following criterion are important to consider:

Types of Grow Lights

LED Grow Lights

Most traditional commercially available grow lights are unattractive, bulky and use excessive amounts of power, and tend to have short life spans as bulbs burn out. With the advent of LEDs many new grow lamps are overcoming these limitations by leveraging their inherent power efficiencies, small size, low cost, and long life.

How LED Grow Lamps Work

The key to LED grow lamp efficiency is that photosynthesis only requires a few spectrum bands. Since plants leaves are typically green, this means green light is reflected, and not used by the plant for growth. Because green light is reflected, a lamp that provides green light is wasting energy. It is common knowledge within the scientific community, that there are only 4 light bands that are necessary for plant growth. The upper blue and ultraviolet bands are most important for plant growth and the lower bands of red and orange are related to plant blooming. LEDs operate in fairly narrow spectrum bands, and so LED grow lamps can target the narrow bands required for photosynthesis and ignore all other bands, thus increasing power efficiency.
