Probably no one will argue with the fact that DNAT lamps are a proven classic, providing a guaranteed yield of any variety of cannabis. Just as there will be no objection to the statement that most of the efficiency of sodium lamps goes to heating. This means that their power consumption is unreasonably high, because the bush needs light, not heat from the phytolamp. Plus, the use of DNAT in the box forces the grower to spend money on an additional ventilation circuit. But you can do without this headache. The solution is to use LED phytolamps.
Not only do they promote the rapid growth of cannabis, but they also saturate it with vitamin E, proteins and carotenoids. The phytolamps are very good for the development of the cannabis root system, increasing the mass and strengthening it. LED lights make photosynthesis and other biochemical processes more efficient, stimulate flowering and the formation of large buds. That is what we will talk about in this article.
Penetration of LED phytolamps in the home
Not long ago, LED phytolamps cost a lot of money. For this reason, they were used mainly by large agro-industrial enterprises. Under the LEDs grew crops, flowers, and even algae. Among the growers could afford such a source of lighting very few. But the main advantage of progress is that over the years, absolutely any technology becomes cheaper.
Today you can buy quite a good LED lamp at a price quite comparable with a set of DNAT + choke + cooling system lamp. And most likely, the price of the former will be even less. This is almost ideal for a medium sized home growbox. As soon as pioneer gardeners were personally convinced of the efficiency of phytolamps, the technology was joyfully welcomed by the entire world grower community. The LED lamps were in immediate and extremely steady demand. This had a positive effect on their cost. In an effort to cover as large a market as possible, lighting manuf
acturers have made LEDs available to a wide mass of people.
The principle of phytolamps
The main feature of LED lamps is their ability to emit only the necessary spectrum of light plants. That is the right spectrum is the main parameter of any phytolamp, which is almost more important than the power and intensity of radiation (watts and mol).
To ensure that the plant could fully perceive the artificial lighting, LED phytolamps set LEDs that emit wavelengths of light of different lengths. Simply put – colored bulbs. Each color is responsible for its area of influence on marijuana development:
The red spectrum, which has a wavelength of 650 nanometers. It stimulates the production of chlorophyll A, which underlies the growth of the stems and leaves of any plant
The blue spectrum, with a wavelength of 430 nanometers, stimulates the production of chlorophyll B. It is essential for the formation of a healthy and firm root system, abundant branching and large fruits
Ultraviolet light, which makes the plant resistant to low ambient temperatures, has bactericidal properties and stimulates the synthesis of more THC
IR radiation, which speeds up the metabolic process
Advantages of LED phytolamps
If we compare LEDs with traditional technology DNAT, it is possible to identify a number of major advantages:
Economy of electricity. LEDs are almost not heated during operation and emit only the spectrum of light needed by the plant. This means that electricity is not wasted, and almost to the full extent (depending on the lamp) is used for useful purposes. On average, the efficiency of an LED luminaire is about 80%.
Long life. The average figure for LEDs is around 50,000 hours of continuous operation. This is equivalent to about 5 years of continuous illumination. Moreover, quality diodes (such as Citizen or Cree) do not lose their effectiveness throughout their lifetime. Whereas fluorescent tubes lose about 10-15% of their radiation efficiency after 3-4 cycles.
Fire safety. As we have already mentioned, LEDs practically do not heat up, while the operating temperature of particularly powerful lamps DNAT can exceed 1000 degrees. Accordingly, you can absolutely not worry about the fact that something can catch fire. Plus, this feature of LED lamps does not create additional problems with thermal management inside the box.
Durability and reliability. LED lighting fixtures do not have in their design fragile elements, which can be damaged by random mechanical impacts.
Simplicity. To connect an LED lamp you do not need a ballast (EB or ECG). Just plug it in and you’re ready to go.
Main types of LED light bulbs
LED bulbs for plants are divided into types depending on the spectra they emit. There are three main types of LED phytolamps:
Bicolor LED phytolamps.
Bicolor phytolamp emits only red and blue spectrum light (660 and 450 nm). Despite the fact that they are the most important for the plant, this lamp is designed more for post-lighting than for a full grov. The fact is that for the most effective development of the bush, other spectra are also needed. However, a bicolor lamp is great for germinating cannabis seeds and the growing season.
Among all LED lights this type is the most budget-friendly.
Multicolor phytolamps for marijuana
Multicolor phytolamps most often emit a warm white, red, blue and far red spectrum. They can maximize cannabis development in almost all phases. Some models of lights even include the UV spectrum.
The following LEDs are usually used in the design of such lamps:
Red, with a wavelength of 660 nm
Blue, with a wavelength of 450 nm
Far red, with a wavelength of 740 nm. Virtually invisible to the human eye
Warm white, with a light temperature of 2900K. White means the plant receives almost all of the light spectrum
A multi-colored lamp can, if it is powerful enough, be used all the way through a hedge. Accordingly this variant will cost more than its predecessor.
Full spectrum phytolamps
This technology has recently become particularly popular. The main difference to the previous variant is that this bulb radiates even white light, which means all spectra at once, but with an increased emphasis on red and blue. This gives the cannabis plants almost natural light and maximizes the effectiveness of the bush. But you have to pay for everything, and not just money.
Apart from the fact that full spectrum, all other things being equal, will cost significantly more than its counterparts, this lamp will “consume” more electricity. But still much less than DNAT.
This option is ideal for particularly light-loving varieties of cannabis, and, of course, under a lamp that can safely carry out the full cycle of grov.
So what LED phytolamp to buy?
It all depends on your tasks. It is not necessary to immediately splurge on Full Spectrum. For example, if you are going to grow marijuana on a balcony or windowsill, it will be enough dosvetki using bicolor. The same option will fit very well in a cloner house.
A multispectrum will fit well in a small grow box with a couple of cannabis bushes. It will save you money on the purchase of the light itself and on your electric bill, while still running a full-fledged grow box.
It’s only if you’re chasing every gram of harvest, or growing more than 5 bushes at a time, doing it in an extremely dark room like a basement, that you’ll need a full spectrum.
