From incandescent to high pressure sodium lamp to LED lights lamp types and plant selection

Indoor plants in the sun without light can light where and when light. They can let you extend the growing season; annual supply of flowers, healthy vegetables and herbs; also can let you in advance before planting seedlings outside Mr. long.

Because of the different spectrum, so there are several types of growth light in the market, from incandescent lamp, fluorescent lamp simple to HID to LED lamp.

The market of several plants in different growth light, as well as the advantages and disadvantages of price:

Incandescent lamp

The incandescent lamp is the lowest priced plant growth lamp. A 150 Watt light bulb as long as a few dollars, you can buy at the local hardware store. The incandescent lamp can keep a small room of the plant growth, but if it is a large indoor garden is not the best choice.

Fluorescent lamp

Since the fluorescent lamp is the low output growth, too large and bulky, can play a good role, so as the growth of light seeds or seedlings. In general, due to low fluorescent lamp lumens, on flowering and germination of plants is not a good choice, a good choice of other plants but they are herbaceous plants and do not need a lot of light. The fluorescent lamp can be found at the local hardware store or garden supply inside the store to buy, the price is less than $40.

The new T5 lighting system is very efficient and bright, maybe even better than the HID lamp in some cases. T5 fluorescent lamp fluorescent lamp is more compact than the old fashioned and efficient, they can be used for all plants, and not just for seedlings. The main advantage of these high-end fluorescent lamp comprises more light can be utilized by plants, than incandescent lamp and HID lamp produces less heat, so it can be more close to the plant.

HID

The bright HID lights, the efficiency is very high, but the price is high. 1 light lamp 1000 Watt HID lamp can be produced with 50 40 Watt fluorescent lamp is the same.

In the HID category, there are several types of bulb: high pressure sodium lamp, metal halide lamp, sodium lamp and low pressure mercury vapor lamp. Indoor gardeners need to worry only or high pressure sodium lamp metal halide lamp. The most common specification is 400 watts and 1000 watts. 400 Watt to about 15 square feet (1.4 square meters) of the garden to provide enough light. A 1000 Watt lamp can cover an area of about 4.5 square meters. In order to rapid growth, every 0.09 square meters can use HID lights about 25 watts.

Metal halide lamp is blue and white, is conducive to the growth and maintenance of leafy plants compact. It is best to use as the main light source. A single light bulb lasts about 10000 cumulative hours. (continuous light bulb will exceed 10000 hours, but the light will be reduced, so it's best to burn before replacement.) Is a power metal halide lamp lumens. Each tile generates up to 125 lumens per watt, while the standard fluorescent lamp produces 39 lumens, standard incandescent bulb produces 18 lumens.

High pressure sodium lamp is orange red, the most suitable for flowering plants. At the same time it is economical, because the average life expectancy is two times of metal halide lamp. High pressure sodium lamp produced up to 140 lumens per watt. Their main disadvantage is that they do not produce light in the blue spectrum. If the high pressure sodium lamp is the only source of plants, so plants will grow long, this is not the most wanted gardener plant type.

How long should be based on plant growth lamp and its needs. Most of the plants and vegetables every day to about 10 to 12 hours of sunlight to grow. Producing fruit or flowers, plants need more time: up to 16 hours a day.

LED lamp

LED plant growth lamp luminous body with LED, can be in the absence of sunlight in the environment, to provide the necessary illumination for plant photosynthesis, plants can make normal or better growth. The LED lamp has strong roots, strengthen the regulation of florescence, promote fruit ripening, enhance color, taste and quality!

In recent years, the rapid development of new lighting technology LED. As the fourth generation lighting source, LED has many different features from other electric light source, which makes it become the preferred source of energy saving and environmental protection. Compared with the previous three similar products, LED light plant growth light stronger and more efficient, lower cost, which can save energy, produce less heat. Fewer calories can make plants more light near the plant, and there is no need to worry about the plant will be scorched. Because of this, the LED lamp can effectively promote the growth of plants is better, so LED growth light is widely adopted in the world.

LED has the following characteristics: plant light wavelength and type rich coincided with plant photosynthesis and photomorphogenesis in the spectral range of half wave width anastomosis; spectrum width, can obtain pure monochromatic light and composite spectrum in accordance with the needs of the combination; can focus on specific wavelengths of light irradiation are balanced; not only can regulate the flowering and seed crop, and can control the plant nutrient and plant system; less heat, small occupied space, can be used for multilayer stereo cultivation combination system, realizes the miniaturization and low load production space.

The advantages of LED light source of high luminous efficiency, long service life, safety, environmental protection and energy saving, so the prospect of LED in the lighting market will be more popular. (compiled: LEDinside James)
