(Experience from Quora netizens)
This is a sudden question-it depends on what plants and how much ambient light they have.
The idea is to create an environment similar to the natural environment of plants.
They are mainly used to maximize the growth of seedlings outside the season.
So it depends on the plants, the time of year and the surrounding natural light conditions.
What is the best LED light for growing herbs?
Of course, there are divergent opinions as to which brand of lamp is the best. For me, it is indeed an advanced LED. They are full spectrum and have excellent PAR.
I use separate lights for my vegetable room and flower room. The output is slightly lower than that of HP bulbs, but the energy saved is more than enough to make up for this.
Expect to pay approximately US$600 for each device in the vegetable room and US$2,400 in the flower room. Advanced LED lights provide a three-year replacement guarantee and an expected lifespan of 5 years.
US returns include free shipping. Full disclosure I do not work for Advanced, but I have purchased and used a lot of their lights.
I find that cheaper LED lights are a waste of time and money. When comparing brands, do your research and make sure to compare apples to apples. There are many cardboard boxes where LED lamps are not worth mailing.
Which is better, LED plant growth lamp or high pressure sodium lamp?
As an experienced person in the use of LEDs. I have tried these two methods. According to cost, efficiency, yield and quality, LED grow lights dominate.
I have worked with many companies. I think they are very good lamps that I have tried so far.
There is no heat when working, so there is not so much temperature management, uniform light distribution and penetration, and lower operating costs! (Although it is more expensive to buy, it is worth it in the long run)
Will LED grow lights hurt your eyes?
LED grow lights can be potentially dangerous to the eyes because they emit blue light and ultraviolet light.
The LED emits wavelengths in three ranges: red, green, and blue.
Red happens to be the least intense of these ranges, but if you are exposed to it for a long time, all three colors are strong enough to cause some damage.
In addition, the spectrum of LED plant growth lamps is narrower than standard fluorescent lamps, which is more suitable for growing plants than general indoor lighting.
The continued concern for its safety has led many people to consider using amber or white LEDs instead of the typical blue or green LEDs used in most plant lights.
The light emitted by the LED is harmful to our eyes
There is a saying that LED lights will harm our eyes and even cause blindness. Of course, if you stare at the LED bulbs for a few hours, they, like any other artificial light source, will be harmful to your eyes. However, if you use LEDs normally, they are completely safe.
Wear protective glasses specially designed for LED lights. Sunglasses can protect your eyes from harmful light, but they will allow you to see the discoloration of your crops, making it harder to spot problems. Planting glasses allow you to observe plants naturally.
What is the difference between LED grow lights?
LED grow lights emit a special spectrum to stimulate plant growth! They grow best in the sun, but when growing indoors, LED grow lights are the best choice.
I believe that LED plant growth lights must emit certain color combinations that are conducive to plant growth.
The color combination represented by the color temperature is usually only predefined by the emission of certain frequencies.
