LED grow lights are not the same as any other led or grow light. They are specifically designed to better on the current HID or high intensity discharge lamp; these lamps are used for growth enhancement and do so by emitting light particles resembling that of the sun. These particles are essential to plant growth whether it's in the garden or in a greenhouse; this is why some plants refuse to grow where you so desperately want them to. Certain other plants which are specifically grown in a greenhouse might need a different lighting environment where the sun shines longer and the night is shorter or vice versa. Not all grow lights are the same as they each only have one or two of the required rays but are enhanced in such a way that it promotes plant growth.
The LED grow light is a newer better grow light when compared to most other grow lights. Other types of grow lights that are also very popular in enhancing growth and are also referred to as HID is the high pressure sodium grow light which emits the right light, just not all the light needed to grow in all the different aspects, another type is Metal Halide combination which emits the same rays plus some ultra violet radiation which is also very positive for the growth enhancement process, but still does not contain everything needed. All these different types do resemble parts of the light molecules needed for growth but it is impossible to copy the sun completely. So the next best thing is to be done and simulated light can sometimes be more of an advantage to plants than the actual sun as the sun also emits light rays that are not all that good, thus slowing the growth process slightly.
LED grow lights on the other hand have been perfected to the point where they could isolate 4 different types of necessary light rays. These rays are specifically targeting the four absorption peaks of the chlorophyll in plants. This means that of all the grow lights this is the one that plants would prefer and that it would make them grow up to 100% faster than natural plant growth. Making this the ideal light for an indoor greenhouse where you want to incubate seedlings and stimulate the chlorophyll for fast healing of plants and faster growth. Then of coarse there is the color of the light which plays a massive role in controlled growth, as some plants would grow fast in a red light for instance. Yet if you place the same plant under a green light, it would have the same effect as leaving it in the dark which will lead to the plant withering and dying. All plants need a cycle of day and night but the cycle length may differ. Especially if you intend to grow exotic flowers or plants, it is very important to check what the preferences of the plant are and to try and recreate the original environment. For the exotic plant to grow successfully out of its natural habitat
The LED grow light gives off an electromagnetic spectrum of light which is then absorbed by these plants. This spectrum can be found on all lights, but growth lights have specialized spectrums which are essential to the photosynthesis process. If your spectrum is not in the right color, it would be like only seeing black and white. And would in fact slow or stop growth and the plant will whither and die. Not only is the amount of light also important but also the distance. These two factors usually work together when determining which light to use and how many as well as how far from the plants can they still be effective. The term normally used by scientists is lumen or lux which is directly proportionate to the distance from the lamp, and the size of the room or container being lit. In other words lumen = the amount of light per square meter. A candle for instance if lit and placed in a square box of 1m by 1m would measure to be 10.76lux( lumen).
Another advantage of the LED grow light is that because it was designed for artificial lighting for plant growth, and contain so many of the necessary light rays, these lights are perfect for growing plants in a hydroponics environment, which leads to even faster growth. Then there are also the benefits of aquatic growth as everything already grows faster in a controlled environment. The hydroponics process is the most advanced and fastest way of growing vegetables and other related plants as this procedure also leads to over sized growth in most vegetables in a record time if administered correctly. This procedure is very close to the concept of a greenhouse only the environment is specifically adapted for increased growth speed, anything can be grown in such an environment and the fruits or vegetables taste will also be affected and it will have a stronger taste than normal.
There is no reason to doubt the superior quality and growth power of LED grow lights, but is this way of growing healthy for the vegetation and for us. What's the point after all of planting vegetables if you're not going to enjoy the fruits of your labor? The thing is if you take something out of your daily balanced diet, you cannot continue to function properly in the same way as you currently are, as we also have a wide range of needs. Does that not mean that perhaps not all the mineral growth is supported or that maybe it does not grow to the feeding value or standards that we are used to? As a matter of fact no, if administered correctly and given all the right artificial necessities, these vegetables can contain more of the needed resources than natural growth.
Is this the way farming might go in the future? I am sure more and more LED grow lights will be used in modern day farming, seeing all the advantages as so clear.
