Grow lights are artificial sources of light, usually an electric light, and are created with the aim to stimulate plant growth through the release of electromagnetic spectrum necessary for the process of photosynthesis.
These lights are commonly used in settings without the presence of naturally-occurring light or where there is a need for additional light. A lot of people use them to grow plants in winter when the hours of daylight are not sufficient for the proper growth of plants.
These lights provide a light spectrum similar to that of the sun or a one which is more tailored to the needs of the plants being grown. They are commonly used in horticulture, indoor gardening, and food production and plant propagation.
LED Grow Lights
A variety of bulb types can be used as grow lights, including:
- fluorescent lights
- HID lamps
- Light Emitting Diodes known as LED lights.
LED grow lights are the newest generation of efficient and highly-economic grow lights, with a significantly reduced size designed with the purpose to be easily incorporated into smaller areas.
In the past, grow lamps were overly hot, massive, fluorescent tubes longer than one meter and they required a lot of stands, cables, and reflectors. On the other hand, LED lights are light and thin enough to be fitted almost anywhere. They have so many benefits and one of them is that people who live in dark and urban or north-facing apartments can grow houseplants without worrying about the lack of light. According to James Wong from The Guardian, using LED grow lights significantly contributes to stronger plants, earlier harvest, and minimal power usage.
The Properties of LED Grow Lights
LED grow lights contain light-emitting diodes in a casing with a heat sink and built-in fans. They do not require a different ballast, and they can be plugged directly into an electrical socket.
They have different colors, and their usage depends on the purpose of the light. To illustrate, green, red, far-red, and blue light spectra are considered good for root formation, the growth of plants, as well as flowering.
It is important to note that LED grow lights need to be kept at least 12 inches away from the plants in order to prevent leaf burn. Even though they have a higher price than other types of grow lights, they are energy-efficient and a long-lasting investment.
