In the event you garden in an inside setting, one of the very important pieces of equipment you should have is proper lighting. These lamps will ultimately mimic as closely as you possibly can natural sunlight for maximum plant growth and progress. One popular choice with growers is a high pressure sodium light source.

The high pressure sodium light, which are categorised as HPS lamps or HPS equipment and lighting, are favored by indoor gardeners that are growing plants that they would like to grow fat medical buds on. The HPS lamps give off light in the orange color spectrums, and plants need this light spectrum so that they can bring on the biggest nugs when flowering. If seedlings were being grown, they would certainly prefer a blue light source spectrum, which helps plants to create vegetation, necessary at the earlier growing stages but less beneficial once the plants reach maturity.

HPS lights are very durable, even as long as eighteen months. They cost less to perform than incandescent grow lamps do also. They produce six times as much light as an incandescent bulb does with all the same watt of consumed energy to perform so.

HPS lamps will likely need to be used in combination with other indoor growing equipment. This will usually include a ballast. A ballast is required to control the electrical current flow towards the light bulb. Because HPS lamps usually run at a higher temperature, some type of a cooling system will likely need to be in place. Most are often used together by using reflectors, which help to improve the spread of the light into a larger area of expanding surface.

A high pressure sodium light can even be combined with a metal halide lamp, which emits light from the blue spectrum. If these two bulbs are put into the same reflector, they could produce all the light than a plant needs to expand from infancy to maturation.

In addition to the high pressure sodium light, many growers are checking out the LED grow light source for indoor garden lighting style. An LED grow light source runs cool, eliminating the need for cooling systems, and they are very light in heaviness, an important consideration once the light fixtures must be hung and also the height adjusted above expanding plants. They also utilize the least amount of energy of any of the HID grow lights, making them economical to make use of in a greenhouse placing, where several lights needs to be purchased and used.

Many of these grow lights are accessible online from grow light source merchants.

      The popular belief is that you need metal halides for vegetative growth (prior to flowering), and High pressure sodium for flowering. I have broken this rule on a few occasions and haven't noticed any dramatic differences.

      Good to know this as I learn more and more about the use of grow lights.
