How Do LED Grow Lights Work?
LED stands for Light Emitting Diodes. The LED’s are made using semiconductor device. They complete an electrical circuit to conduct electricity and also find in various other devices such as TV screens and traffic lights. The LED’s do not have a filament and do not burn out too frequently like the conventional bulbs. They also have a very low heat output. Since the LED lights function due to the effect of moving electrons that are constantly jumping from a lower to higher orbital and vice versa, they are able to emit packets of energy known as photons, which are the same as those received from natural sunlight. Therefore, the LED indoor grow lights can easily support a natural and healthy growth even in plants that are kept away from sunlight.
What Should You Know About Watts?
Wattage is the rate of energy input required for normal functioning of the LED lights. They usually have very low energy input as compared to the incandescent bulbs while giving a more light output which is measured in lumens. Unlike incandescent bulbs that give more output at higher watts, the LED’s become less efficient as the wattage is increased.
What Should You Know About Light Wavelengths?
There are different wavelengths in the visible spectrum of light, and some of these are more important for photosynthesis. Studies have also revealed that the wavelengths in the red and blue regions are more important for proper growth and development. Therefore, it is important that the LED grow lamps you choose are able to emit these wavelengths vital for the important photosynthetic reactions in plants.

What is Full Spectrum LED Grow lights?
- Colors Of The Spectrum
Spectrum is nothing but the range of wavelengths given out by a light source. A full spectrum LED grow light is that which is able to emit the lights of all different frequencies in the visible spectrum. It is important to note that the different LED lights may not be consistent as far as their spectrum is concerned. It is quite natural for the colors to vary depending on the crop for which it is being used. Most LED lights focus primarily on the red and blue region. However, the ones with a wider spectrum can be used in a more versatile manner.
- The Right Combination
Plants have different types of photoreceptors present in them. These receptors are the most important in determining their sensitivity to various wavelengths. The combinations can differ slightly depending on the manufacturer and the model. Most have 3 or four band LEDs with red and blue as a compulsory inclusion. Colors such as yellow and green are not seen much in such lights. Some manufacturers also use white LEDs to make up for any shortages in the wavelength range.
Why Just Red & Blue Color LED Grow Lights Typically Don’t Work Well?
Most LED lights tend to emit only the spectrum that is considered essential for the photochemical reactions in pants. However, it is also observed that HPS lights which produce neither of the blue or red lights are able to give perfectly healthy plants with a high yield. A feasible explanation is because keeping the plants restricted to certain wavelengths complete the cycle when the plants are still immature, thereby putting them into a chill mode after which results in stunted plants and lower yield.
What Do You Need To Know About Light Cycles?
Before going deeper into the optimal spectrum required for healthy plant growth, it is important to have a good knowledge about the light cycle. Basically, there are two phases in the light cycle that are known as the vegetative and the flowering phase. During the vegetative phase, the plants absorb those wavelengths from the spectrum that are required for proper development of the roots, shoot, and foliage, thus preparing the plant for the flowering phase. If you start right from the germination, you can do without a lot of light during the early phase, when the sapling barely has any foliage. During this time, it is more important to tend to proper warmth and watering.
The cannabis has a slightly different light cycle as compared to other plants. These lights do not have a sleep cycle but require a lot of time in the dark, mainly for developing strong roots. It is important to keep the cannabis plants in the light for 18 hours and in the dark for 6 hours. After the flowering phase is triggered, this should be changed to 12 hours on and 12 hours in the dark. During this time, it can also be beneficial to switch to HPS bulbs rather than the red and blue LEDs.
The LED lights use Light Emitting Diodes for emitting the lights of various wavelengths. They do not cause incessant heating like other grow lights and also have a very low energy intake. The HID or the High-Intensity Discharge lights are also commonly used in growing indoor plants but are more popular in growing cannabis. HPS or High-Pressure Sodium light is a type of HID lights and mainly emits wavelengths from the blue end of the spectrum. For the perfect growing yields, many farmers switch from one type of the light to the other during different growth phases.
