Led Grow Lights Make Stealth Growing Easy!

led grow lights are the new favorite for Stealth Growing, as they provide many advantages over other grow lighting. LEDs are unlike light bulbs, as they do not contain a filament that burns out. Instead LEDs use a diode, which is a semiconductor that converts electrical current into light. As a result LED Grow Lights can be used for 50,000 - 100,000 hours before it's time for a replacement. LED Grow Lights also emit less heat than T5 Fluorescents, making them a better alternative for Stealth Grows. Flowering response is also much stronger under LED Grow Lights than HID or T5, making them a much more viable option for large-scale and commercial stealth grows.

Red LEDs

    The most effective type of Red LED light is one that falls on or around 660nm. This will produce the best results for plant growth as it is comparable to High Pressure Sodium lamps and 2700K Florescent lights.

Blue LEDs

    The most effective type of Blue or cool white LED light is one that falls on or around 880nm. This produces the best results for plant growth and is comparable to Metal Halide lights or a 6500K fluorescent light.

Potential

    LED lights consume less energy and produce little or no heat, which makes it perfect for growing plants and saving money on energy.

Effect of various wavelengths of light on plants

To facilitate the study of the color properties of light , The visible spectrum surrounded by a ring, And divided into nine regions , Called color ring . Color shade ring numerals corresponding wavelength in nanometers (nm), any two color rings on the top position in the color sector , mutual called complementary color .
 For example , blue (435 ~ 480nm) of the complementary color is yellow (580 ~ 595nm). Found by the shade has the following characteristics :
( 1) complementary color obtained by mixing a certain percentage of the white light . Such as blue and yellow mix get is white . Similarly, glaucoma and orange light is also obtained by mixing white ;
( 2 ) any color on color rings can be used on both sides of two adjacent monochromatic light can even copy from a mixture of two monochromatic second nearest neighbor . Such as yellow and red mix to get orange light. More typical is mixed red and green become yellow ;
( 3 ) If you choose three separate monochromatic light in color ring . Can be mixed in different proportions may occur in daily life into various shades . The three primary colors of light is called monochromatic . Optics primary colors red, green and blue. Note here that the pigment primary colors red, yellow and blue. However, the primary colors of choice is completely arbitrary ;
( 4 ) When the sunlight of an object , a light of a wavelength absorbed by the object , the color displayed object (reflected light ) for the complementary color shade . As the sun light shines on the object right, if the object absorbed wavelength 400 ~ 435ntn violet , the objects appear yellow-green. Here it should be noted : Some say the color of the object is an object absorbs other shade, the color of the reflected light .
This argument is wrong. For example, yellow-green leaves, actually only absorbs wavelengths of 400 ~ 435urn violet , yellow-green is showing mixed results reflected other shade , not only the reflected light yellow-green. 1 , the impact on plant physiology spectral range 280 ~ 315nm: effects on morphology and physiological processes is minimal 315 ~ 400nm: Chlorophyll absorbs little impact photoperiod effect , prevent stem elongation 400 ~ 520nm ( Blue ) : the proportion of chlorophyll and carotenoid absorption maximum , the greatest impact on photosynthesis 520 ~ 610nm ( green ) : pigment absorption rate is not high 610 ~ 720nm ( red ) : chlorophyll absorption rate, has a significant influence on photosynthesis and photoperiod effect 720 ~ 1000nm: absorption rate, stimulate cell elongation , impact of flowering and seed germination > 1000nm: converted into heat 2 , from the above data, the need for plant photosynthesis light wavelength of about 400 ~ 720nm. 440 ~ 480nm blue ) light and 640 ~ 680nm ( red ) for photosynthesis greatest contribution . 520 ~ 610nm ( green) light is absorbed by the plant pigment ratio is low .
In accordance with the above principle, plant lights are basically made ??of a combination of red and blue , all blue , all red in three forms , covering Wavelength range for photosynthesis . The visual effect , the combination of red and blue lights showing pink plants . Special White pointed out that with the green light for photosynthesis similar , and no action
.Red and blue lights chromatography proportion of plants in light of the general Is preferably between 5:1 to 10:1, usually 7 to optional ratio 8:1 . Of course, conditional proportion of red and blue light can be adjusted according to the best plant growth cycle .
When the plants with a plant light fill light , the distance of the blade height is generally 0.5 to 1 meter

LED grow lights for flowers

Deciding on the right kind of LED grow lights is really critical for every consumers because each light is used for special plants and flowers, so based on the plant that the individual wants to nurture, he should go for the correct light for his use. Firstly, every grower must be familiar with the low quality lights from the excellent lights. The lesser quality can yield such medium heat as to allow the seedlings to grow only and not the whole plant. Then you ought to be conscious of the light color you want to get for your plants. Commonly people believe white and green color lights to be crucial for the growth of the plants, but this is a very incorrect belief since green light is always reflected by the plants because of the green chlorophyll and white light does not radiate an adequate amount of energy to facilitate the plant to make its food. The best colors for the proper growth of every plant are blue and red.

These colors assist the most in photosynthesis. Other colors of led grow lights are helpful for plants but they unaccompanied can not give enough energy plus heat to aid in photosynthesis. Other color lights need to be in combination of 2 to 3 colors to make the procedure happen correctly. If anybody is trying to produce herbs and vegetables only, then he ought to use blue LED's only, because these transfer strength to the roots in addition to the stems to grow healthy. The leafs also need more energy from blue light in contrast to other colored lights for the reason that blue light helps to combat diseases, so it keeps the plant healthy to grow more quickly.

The red LED grow lights are used mostly for growing fruits and flowers at the greatest pace but with all the health required by the plants. The red color, being similar to autumn season, alerts to the plants to produce seeds in the form of flowers and fruits. This color is very effective for the growing of fruit plants since the red color gives out the most energy and heat to help the plant grow strong.The combination of these color lights is also useful for the growth of plants but not to that extent that every plant will definitely need a double spectrum or a tri-band spectrum. These combinations are only made to bring variety and create a range of color lights in use. The most frequent is the mixture of red, blue and orange light, which is used for every plant.

A variety of other combinations like that of red, white and pink, or of blue, white and yellow are also advantageous for fruits and flowers or herbs and vegetable in that order. The LED grow lights are available in varying sizes in respect to the quantity of plants required to be grown. The size of these lights go from 3mm to 10mm, with the lesser ones used for a small yield of plants, while the larger light for the bigger yield. But one ought to always keep in mind to never use the bigger size of light for a smaller bundle to make the plants grow rapidly, as it will only hurt the plants and flowers.
