What is ultraviolet light? Ultraviolet rays are radiation in the visible spectrum and invisible spectrum. The shorter the wavelength, the less visible and harmful. Based on the wavelength, there are three different types of ultraviolet radiation.
UV-A radiation (from 315 to 420 nm)-almost invisible to the human eye, UV-A has the longest wavelength, the least damage to the human eye, and the highest efficiency. Most of the UV-A radiation emitted by the sun passes through the ozone layer, so it is the most abundant form of ultraviolet
UV-B radiation (from 280nm to 315nm)-mainly used for water disinfection and decontamination, to ensure that mold and spores will not grow on plants. This is achieved by limiting the bacteria in the water. Molds and spores usually adhere to and grow from the water.
UV-C radiation (usually below 280nm)-these wavelengths are usually filtered out by the ozone layer and usually do not appear in sunlight. However, under the correct dosage, UV-C can promote plant growth. This wavelength ensures that the insecticides and molds found during the growth of plants are limited/killed so that the plants can thrive under optimal growth conditions.
