Until the invention of high pressure sodium grow lights, a form of high intensity discharge (HID) lighting, a successful year-round gardening season seemed only a fantasy to eager indoor gardeners. With the development of HID lighting came a fantastic way of growing your plants throughout the year and avoiding those frustrating winters. To ensure a productive indoor growth and provide your plants with sufficient light that they need, it is wise to take a look at high pressure sodium grow lights.

Long-time gardeners know that in the past fluorescent lighting was the most popular "grow light" alternative. Its benefits, albeit limited, helped to stimulate plant growth. Now the availability of high pressure sodium grow lights are more energy efficient, broader in spectrum range, and longer lasting.

The Difference of a High Pressure Sodium Grow Lights

High pressure sodium grow lights provide your garden with a light source that traditional incandescent or fluorescent lights cannot. Rather than relying on a filament, these special light bulbs use a capsule of sodium gas that is produced by the energy between two electrodes. This reaction creates a greater amount of light than an ordinary bulb can, and at the same time uses less energy.

High pressure sodium grow lights cover the red and yellow regions of the spectrum, thus making them the best choice for flowering and fruiting plants. A good lighting retailer will most likely carry the lights you are looking for, and will be glad to help you determine the lamp that best fits your needs.
