Can I use regular LED lights or do I need LED grow lights? You can use regular LEDs but you’ll get better results with LED grow lights. LED bulbs and strips usually produce white light, which is helpful for general plant growth. However, plants really need blue and red light to thrive.
Technically, Yes you can use any LED lights to grow plant indoors if your LED offer enough PPFD. But regular LED lights aren’t powerful enough to emit a specific chunk of the light spectrum that is present in natural sunlight.While red is most efficient for photosynthesis, having only red light would result in poor growth such as very elongated stems, so blue is added to keep plants compact and a more typical shape.
IR and UV, what’s the difference ?
IR and UV radiation are a small part of the electromagnetic spectrum. The visible light has a wavelength of 380 nm to 760 nm. The area alongside with a longer wavelength is the IR spectrum. The majority of the IR radiation on earth comes from the sun. The area next to the visible light, with a shorter wavelength, is the UV spectrum.
Each wavelength transports a certain amount of energy. The faster the frequency of these waves, the shorter the wavelength and the more energy the radiation can transport. So the shorter the wavelength, the higher the frequency of the radiation, the more energy is transported into it.
This means that radiation with a short wavelength can penetrate deeper into material. Because the IR radiation has a longer wavelength than the visible light, it is in principle not harmful to the human body. Of course by the application, the heating of material, you must always take into account that the product and the adjacent parts can also become hot.

What means infrared?
Infrared or IR radiation, like ultraviolet or visible light, is a portion of electromagnetic radiation, ranging from 700 nanometers (above visible light) to 10,000. This is classified into several divisions depending on its wavelength : short, medium or long wave.
What is ultraviolet radiation?
UV light or ultraviolet radiation is a part of the electromagnetic spectrum below the visible light, with wavelenghts from 180 nm to 400 nanometers. It’s classifies in three ranges according their effects: UV-A, UV-B and UV-C
UVA — From 320 nm to 400 nm, where visible lights begins. This radiation is capable of penetrating any substrate (paper, inks, coatings..) and in used frequently in the industry in deep curing processes. Our skin has developed UVA ‘control mechanisms’, and therefore is not very harmful if the doses are not superior to, for example, a normal exposure to sunlight. But we must remember that this radiation ages the skin.
UVB — Is defined as the radiation between 280 and 320 nm. In spite of having a major energy than UVA, it does not penetrate so deeply, but it produces curing faster. Our skin is not well protected against the UVB radiation due to the fact that only a small quantity comes to us across the ozone layer. The radiation UVB ‘burn’.
UVC — This is the section between 200 and 280 nm. This is a high-energy radiation that falls as soon as collides against any surface. Therefore in the industry is used to cure surfaces.
