A grow light is an artificial light to help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated. Outdoor conditions are mimicked with varying colour, temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps.
LED plant lights with a lot of blue and UV diodes can be harmful. The same goes for all-white lights that emit a cooler white light (5000 Kelvin and higher). The type and amount of harm an LED light can cause depends on the color and the intensity.

Nov 14, 2019 · Many LED grow light suppliers have conflicting information on the topic due to bad marketing or simply a lack of knowledge in plant and light research. In this article, our light spectrum experts break down what light spectrum is, how plants respond to light, and how light spectrum influences plant growth.
Sep 30, 2020 · The UVA light lies between 320 to 400nm while the UVB light lies in the range of 290 to 320nm. More specifically, the UVA light is the best suited for marijuana plants as it helps them with many characteristic features such as their taste, and even the kind of ‘high’ that you get with it depends upon this light.
That being said, there is definitely a desirable range when it comes to the amount of light a cannabis plant receives. Although that range varies depending on the type of plant (Indica vs. Sativa) and strain, most plant’s ideal light levels fall into the range below: Vegetative: 35,000 – 70,000 lux …
Sep 30, 2013 · The light intensity of a UV-C germicidal light bulb is usually expressed in a term called „microwatts per square centimetre“. Mr. Aiking and Verheijen suggest a range between 2,500 and 150,000 mircrowatts of UV-C energy over a given 24 hour period.
UV-A light can be used to control plant diseases and stimulate production of some biochemical compounds contributing to plant taste and aroma. Some growers use supplemental UV bulbs and some LED grow lights contain UV-A in their spectral output. However, there is a downside. The quantum efficacy of UV LEDs is low due to high energy of UV photons.
Jul 22, 2016 · The Ultraviolet (UV) spectrum ranges from about 100 nanometers (nm) and 400 nm. UVA, from about 315 nm to 400 nm, is an extension of the deep blue light spectrum and is included in most artificial light sources. Some level of photosynthesis occurs in this range. UVB, from about 280 to 315, is somewhat damaging to plants in high levels and causes sunburns on humans.

· 1） The grow light was designed with red & blue light, give off perfect wavelength for all growing stage. Suitable for seeding, germination, vegetative & flowering. 2） Easy set up: hanging kit make this grow lamp much more easy to assemble. ABS material body, excellent chips helps your plants grow better.
Ultraviolet (UV) light has a wavelength shorter than 400nm and contains more energy per photon than light in the 400-700nm Photosynthetic Active Radiation (PAR) region of the spectrum. There are plenty of reasons to leave UV light out of an LED grow light. UV LEDs cost 10 times more than LEDs in the PAR region of the spectrum. UV light doesn't count toward PAR / PPFD measurements.
Mar 02, 2020 · A further benefit of using UV-A in plant growth relates to the difference in how a bee sees light compared to the human eye (which is explained in greater detail below). The use of UV-A enhances the growing environment and enables bees to pollinate the plants with ease.

Most of the UV-A radiation emitted from the sun passes through the ozone layer and, thus, it is the most abundant form of UV. UV-B (280 to 315 nm) and especially UV-C (100 to 280 nm) radiation are the most dangerous to people as well as plants. Fortunately, the ozone layer absorbs most UV-B and all UV-C radiation. Sources of UV.
Aug 02, 2018 · The Importance of UV and Infrared Light for Growing. Many people are familiar with the different colors of the light spectrum that are optimal for growing during the different stages of plant development. In an earlier blog entry, I discussed how white light was optimal for seed and clone development, violet/blue light (400-500nm) was vital for the vegetation stage, and orange/red light …
Dec 03, 2020 · Modern grow lights provide a full spectrum of light for your plants, including UV wavelengths that are harmful to human eyes. If you’re interested in protecting yourself from harmful UV-A and UV-B electromagnetic radiation, LED and MH grow room safety glasses —or the HPS and MH variety—are an excellent investment.
