2. How to Choose the Best LED Grow Lights for indoor plants?
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.
Shape of the Light
LED grow lights are available in a variety of shapes from panels to saucer shape and even light bars. 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 quality LED grow light. 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 grow light 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 led grow lights for indoor plants , 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
Plants requiring lower amounts of light: around 14 watts per square foot

3. Advantages of LED Lights for Indoor Growing
You may be wondering why you should even choose LED grow lights over other choices out there. There are some clear advantages you should be aware of. LED lights are often power and energy and saving, which translates to dollar signs. You will feel less impact on your energy bill at the end of the month if you are using LED lighting.
Another great advantage is that LED lights can be chosen in different colors or adjusted to mimic the outdoor light your plants would be getting in each season. This boosts growth and success in your indoor garden.
LED lights are usually much smaller than traditional grow lights, meaning you won’t need a large dedicated space to set up your indoor garden. This is perfect for anyone who lives in a smaller space but still wants to take part in indoor gardening.
While LED lights might cost a little more initially, you can expect they will outlast traditional lighting since they tend to illuminate for many more hours per light. Over time this will translate to savings for you.
4. 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.
