2. How to Choose the best lights for indoor growing?
You may be thinking— “Aren’t all grow lights basically the same?” but this is not necessarily true. When you are purchasing grow lights for the first time, or even replacing old ones, you should look for these key features or characteristics when considering one light over another. These points will help you conclude which is right for your specific case.
This is the first feature you should consider. Plants are not only need red and blue spectrums, but also infrared and ultraviolet rays. So, the full spectrum LED grow lights will give higher yield than the others

It is best to consider where you will be setting up your indoor growing space and this will assist in deciding which shape is suitable for you. Smaller lights are great for smaller space but also for setting up in scattered patterns, whereas a panel light covers longer stretches of space.
Hours of Burn Time
Not all LED lights burn at the same rate. You should always check to see what the estimated life expectancy of each light is prior to purchasing. A higher dollar amount does not necessarily mean you are getting the best value or the best LED grow lights high times. Read the packaging to see how long you should expect to have this light before it needs replacing.
Excellent Quality Internal Chip
At the heart of every LED light is a chip which will convert your electricity into light. This chip must be of high quality to ensure there is enough powerful light to get your garden growing. A good rule of thumb is to find an LED light with a chip of at least 3 watts, so you can be sure it has enough luminosity to get the job done.
Lower Heat Generation
This is an important key feature for any LED growing lights you purchase. Some LED lights will output higher heat and create a warmer environment in doing so. In turn, you would have to cool your space with fans to have the proper growing temperature for your plants. To save yourself having this set up, it is much simpler to purchase LED lights with a low heat output. Not only will they generate less atmospheric heat, they tend to last longer since they are not burning so hot at a constant rate.
Ease of Use
Even if you are not new to indoor gardening, your time is important. The last thing you want to be doing is tinkering with your LED grow lights for hours trying to get them adjusted just right. Choose an LED light which is simple and easy to use. This means you should be able to easily set the height and intensity without much fuss.
Size of Your Expected Garden
Before purchasing any best lights for indoor growing, you must know exactly how big your indoor growing space will be. This will help you decide how many lights you will require and could sway the shape and size of LED light you choose. A great guide to how many lights you will require is:
Plants requiring higher amounts of light: around 32 watts per square foot

4. Growing cannabis with LED grow lights
LEDs have become so popular among cannabis growers, for good reasons. They have been around for some time, but in recent times have become more popular for several reasons. One reason why LEDs are good for growing cannabis is energy efficiency.
Compared to other types of lighting used for indoor cannabis cultivation, LEDs consume considerably lower energy to provide the lighting required by the plants. Also, the LEDs being produced nowadays offer specific spectrums that are needed for healthy cannabis cultivation. Typically, they can produce a full spectrum, but they become more efficient when targeted at the particular spectrum needed by the plants.
Furthermore, they produce low heat. A high heat production implies an increased risk of heat damage to your cannabis plants. However, that risk is eliminated with LEDs as you can install them closer to your plants with no worries as regards the heat level they produce.
Also, a good LED light will help you avoid hot spots that result from the concentration of light on a particular section of your plants. LEDs are designed for even light distribution over your plant canopy, ensuring an even growth ratio.
5. How are LED grow lights better and worse than other types of grow lights?
Nowadays, there are so many types of grow lights you can get on the market. However, they can be classified under any of three categories: high-intensity discharge, light-emitting diodes, and fluorescent. Here is how these other types compare with LED grow lights.
Type of Grow Light
LED (Light-emitting Diode)
LED lights offer the full spectrum required for indoor plant cultivation. Compared to other grow lights, they are the most efficient in energy consumption, producing the lowest level of heat. Furthermore, LEDs have a longer lifespan compared to other grow lights. However, the light produced by LEDs is not good for your eyes.
HID (High-Intensity Discharge)
This grow light consumes way more energy than LEDs. The lifespan is considerably shorter compared to LEDs, and they produce a high level of heat. To prevent heat damage to your cannabis plants, they should be installed at a distance from the plants. There are many high-intensity discharge lights to choose from.
Fluorescent grow lights are really affordable, and they have a reasonably long lifespan. However, they will not last as long as LEDs, and they are not the best grow lights to use during the flowering stages. Like HIDs, there are so several types of fluorescent grow lights to choose from on the market.
6. Why Colors Are Important In Plant Growth?
It is common knowledge that plants get its food from sunlight and that this process is called photosynthesis. What may not be common knowledge; however is that the color of the light absorbed by the plant has a direct impact on the amount of energy consumed by the plant. This is because different lights have different wavelengths, and these wavelengths, regardless of their lengths (long or short) produce different levels of energy.
The highest light energy is at the purple or violet end of the color light spectrum. Since purple and violet lights have short wavelengths, they provide lots of energy. On the other hand, the red light found at the opposite end of the light spectrum from that of the purple and violet have a long wavelength and so produces less energy.
Whether the light being emitted is red or purple, plants will still absorb some energy from the light that is being reflected. Different lights have different functions. Blue, for example, helps in vegetative growth, the combination of red and blue helps plant flower while cool fluorescent light is ideal for growing plants indoors. With advanced LED technology, the kind of light being emitted can be controlled to achieve better results.
Effects of Each Color of Light on Indoor Plants
With the invention of LED grow lights, they can now be used to manipulate the physical characteristics of plants to suit your desire. Some of these lights and their effects on plants include:
