Hydroponics Gardening with LED Grow Lights

With a Hydroponics gardening system you use grow lights to light the plants properly in order for photosynthesis to occur. Choosing the best lights will ensure that the plants grow and thrive. Grow lights are crucial in any indoor gardening situation, because without adequate light, the plants will be stunted and not grow to their full potential. This is one of the reasons that LED grow lights make an excellent choice for growing plants indoors.

LED refers to light-emitting diode. A diode has two terminals, and it allows current to flow in one direction and not in another. It is a simple semiconductor.

Photons are units of light. Atoms contain photons, and it is the photons that produce light. They produce light when electrons move around and change positions. Electrical current, in an LED lamp, flows across the diode, and when this happens, it causes a change in the movement of the electrons. The positively-charged electrons will move in the opposite direction from the negatively-charged electrons. A semiconductor is made more conductive to electrical flow when free electrons are added to the conductor material, creating negatively charged areas, or when they are taken away, leaving gaps in the chain, and positively charged areas. Electrical current flows over these areas, and it causes the electrons to move. The side effect of all this movement is the production of light.

The color of the light emitted by these types of grow lamps is based on the size of the gap in the electron chain. The gap size affects the frequency of the photon, and this is why it has an impact on the color of the light produced. Low-frequency light produced by an LED light is used to light remote controls for one of many common examples, because it it infrared light.
