Plants need three things to grow and thrive: water, soil, of course, there are sunlight! Ideally, water and soil are easy to obtain, but if you plan to plant anything other than indoor plants indoors, it is a considerable challenge to provide sufficient sunshine. Even if your apartment or house has many windows, you may not be able to get enough sunlight to ensure your indoor garden happiness. Especially in winter.
Usually, your ordinary indoor lights are not suitable for indoor plants, which is a place for plant -growing lights. Plant growth lights provide “sunlight” in the form of artificial lighting. ‘With appropriate lighting, you can produce a variety of indoor plants -the lighting you choose depends on the light requirements and areas that need to be covered. Continue to scroll to understand more information about the best LED grow lights that promote fast -growing indoor plants!
The colors blue and red are considered the best for a plant’s growth and development.
Chlorophylls quickly absorb these color combinations to produce food and energy for the plant; hence, directly helping with the photosynthesis process.
Plants enjoy a higher amount of red, up to 5 times as much as blue.
Blue wavelength helps with root development and strong stem growth, while red wavelength helps flowering.
However, blue has a relatively high amount of energy that can easily damage the plant’s growth with the shortest wavelength among the two.
Therefore, it needs to be carefully mixed with red to limit its overexposure. On the other hand, too much blue light may stunt the root proliferation and prevent vertical growth.
Here is an exciting surprise for you!
Plants only use blue and red light colors for growth is a myth!
Plants are grown with 80–90%red light and 10–20% blue light helps achieve fuller plants with lush thick foliage and appropriate stem lengths.
You may find some artificial grow light to be purple, which contains a combination of red and blue lights.
It is known to be beneficial during the vegetative cycle of plant growth.
However, they emit a higher level of lumens, are quite expensive, and only emit a combo of red and blue, which may not be effective for even plant growth.
A plant requires a combination of various light colors throughout its life span.
Keep this in mind, especially if you are trying to grow plants with the assistance of artificial grow lights.

1.Coverage Area & Light Distance
First of all, you need to know the size of the grow space that your plants will be growing in. Measure your grow space — length, width, and height. Knowing what size grow area you will be growing in is arguably the most important piece of information to know when shopping for LED grow lights . A LED grows light manufacturer will design their grow light for a specific coverage area. The most common coverage areas are 2’x2’, 2’x4’, 3’x3’, 4’x4’, and 5’x5’. As you can see, the length and width are mentioned, but not the height. Hang tight. We will talk about the height of your grow space in a minute. Once you measure your grow space and know what area you need your LED grow light to cover, you can narrow down your search results by filtering to show LED grow lights specific to your grow space.
Now, what about the height of your grow space? That comes into play when we talk about light distance. Every grows light listing should state the coverage area as well as the recommended light distance. The light distance is the distance between the grow light and the top of your plants. Light distance is another thing you need to consider when buying a LED grow light. I’ve had several growers contact me asking for advice on plants that grew too close to their grow light — because they did not factor in the light distance when buying their LED grow light. Let’s go over a quick example. Say your grow space is 4’x4’x6’ (L x W x H) and the recommended light distance on your LED grow light is 24”. So, 6’ (height of grow space) minus 2’ (light distance) equals 4’ tall plants? Right? Wrong! You should also consider the grow pot (which often takes up about 12” depending on the grow pot size) and the “lost distance” above the grow lights which is taken up by the grow light hanging kit.
2.Wattage
This is the most common measure of grow light intensity and is a measure of electricity (watt = amp x volt). This measure can be misleading, though. Some manufacturers (the better ones) give the actual wattage the unit uses — the wall plug wattage. Others, typically lesser brands, will give you the max wattage rating of the LED diodes. To use a simple example, a grow light could call itself 90 watts if it has thirty 3 watt LED’s, however, it is common practice to run LED’s at half wattage to reduce heat production (and therefore heatsink cost) and increase efficiency. So, what was called a 90w grow light could really be 45w (or less!).
Bottom line, you want an actual power draw, not an LED wattage rating. It can be good to be suspicious of overly round numbers — you are likely getting the diode rating and not the actual power draw. Knowing the wattage of the diodes isn’t useless, though. You will get a heck of a lot more light out of a 3-watt diode run at 1 watt than a 1-watt diode run at 1 watt.
3.PPF
PPF (Photosynthetic Photon Flux) measures the total amount of light produced by a grow light in terms of micromoles of photons produced per second (often written as umol/s or μmol/s). This is an important number because unlike PPFD (which will be explained below) it can’t be manipulated and tells you the full amount of light coming from the LED grow lights .
4.PPFD
PPFD (Photosynthetic Photon Flux Density) measures the number of micromoles of photons striking a square meter per second (often written as umol/m2/s, μmol/m2/s, or μmolm-2s-1).
Full daylight sun at noon in the summer is around 2000 μmol/m2/s. What your plants actually need, however, is likely to be much less than that. In fact, because the Sun’s intensity is only that bright for a small portion of the day and because the angle of that intensity changes throughout the day, providing that much light for an extended period of time would very likely be damaging to your plant. A ‘light response curve’ shows how effectively a plant utilizes light at differing intensities. Depending on the plant, at levels greater than 800–1000 μmol/m2/s the efficiency that a plant uses the light starts to slow. Meaning, you can provide your plant more light than this, but you might not see a huge change in outcome.
It’s worth noting that some LED companies can increase their PPFD numbers by measuring extremely close to the grow light or using spot-light like reflectors or lenses. An LED company should always report what distance their PPFD numbers were taken at (e.g., 24 in, etc.).
5.PAR
This is not a measurement at all, but instead, a type of light that can be absorbed by plants (and coincidentally seen by humans). It ranges from 400 to 700nm.
With all the grow light options on the market today, it can be hard to pick the best and stay within your budget. Fortunately, we’ve looked at some options that may benefit your choice and budget without going overboard. There are many other options besides what we have listed. But you now have an idea of the features to check before buying. When it comes to choosing the cheapest grow lights online, it all goes well.
