Best 300W LED Grow Light Review

According to their name, LED grow lights are luminaires using LED chips in a modern and effective way to make light for growing plants. LED grow lights are available in many shapes and sizes but as the most necessary components of LED grow lights LED chips have the majority of the influence on the level of the light, i.e. spectrum (colors) and photon flux ("brightness") produced. Since LED grow light producers can pick the LEDs they utilize in their lamps, it's important to understand which sort of LED grow light best matches the particular application. Among the benefits of LED grow lights compared to conventional lighting solutions is the ability to match the light to the requirements of plants.

Like most new technologies, the range in quality and prices of LED grow lights is broad, and that could make choosing your very best option How do you choose one of all of the LED grow lights and find the best one for you and your plants?

Here are a few of the main things I have learned from working with LED grow lights, written in language that is meant for plant-people. If you are new to LEDs, I hope that this can accelerate your learning curve. And if you are an expert, please discuss comments that could also help people that are only entering this remarkable new grow light age.

What Light To Pick?

Are you wondering what type of grow light you want for that indoor growing experience that you want to begin so bad?

With the recent explosion of hydroponics, indoor growing, as well as the LED grow light industry, it is not surprising that there are a slew of businesses in the industry right now. And with so many possibilities, making the ideal choice can become quite a hassle really quick once you scroll past dozens of lighting choices.

So, so as to make your task of choosing the right LED grow light for your backyard a bit easier, I have decided to make it my job to examine the hottest LED grow light offerings available in the marketplace.

Today I am reviewing one of the most accessible generic offerings. They've been around for quite a long time and have established themselves as among the most common go-to options in the introductory sector.

Which Are LEDs And How Do They Work?

LEDs (Light Emitting Diode) are small electronic components made from two unique kinds of semiconductor material, one with a negative charge, called electrons, and the other having a positive charge, called holes. When voltage is correctly implemented over an LED, electrical current starts to flow through it making holes and electrons begin to collide releasing energy in the form of photons, light quanta, in a process called recombination. The first LEDs had relatively low light output and limited collections of colours while contemporary LEDs have high brightness and come in all varieties of colors in visible, infrared and ultraviolet spectral ranges.

What's the Effect Of LED Grow Lights On Plants?

Color variations of this LED grow lights are directly linked to the intended function -- various studies have demonstrated that certain colours influence plant growth, affecting origin and flower formation (blue and red light spectra) which practically means that nearly all plant sorts will finish a normal growth cycle when subjected to both blue and red grow lights. Adding different colours into the spectrum, such as green, far-red and deep-blue helps this process by giving plants more information about its surroundings and overall leading to higher quality plants (faster growth, more secondary metabolite accumulation etc). A spectrum which has all colours is called complete spectrum and largely resembles the sunlight. If it's high proportions of green, the light will appear white to human eyes and while not a vital element for plant growth, it will make the job around these lights simpler and makes visual inspection of the plants potential.

Selecting a Grow Light Form -- Grow Bulbs vs. Lighting Fixtures

In case you swap out the bulbs in an existing light with special grow bulbs, or if you purchase a brand new fixture with built-in lighting? It all depends on what you're looking for -- cost and convenience or specialized quality.

Grow light bulbs would be the cheaper option. For most people, it is a lot easier to use also. Just take an old lamp or ceiling light which requires bulb replacement, and soda in a specially-designed grow bulb.

Grow light fixtures are more expensive, but they provide a more holistic solution. A single fixture can offer the illumination for numerous plants, dispersing the lighting evenly throughout the room. Because these fixtures are especially designed for grow light functions, they tend to supply a fuller light spectrum range than more economical light bulbs.

What Color Light is Best for Plant Growth?

Violet-blue light in the 400 -- 520 nanometer range promotes chlorophyll absorption, photosynthesis, and growth.

Red light in the 610 -- 720 spectrum ranges promotes flowering and budding.

Grow lights should offer the appropriate spectrum of light for photosynthesis, which key to plant growth. Before buying a light, make certain to check out the supplied color spectrum. Lights that can offer a complete spectrum are the best choice for your growing space.

This is where LED lights come in handy. Most LED growing lights provide both kinds of colour spectrum lighting, which means that you can receive all the advantages.

Suggestion: Violet-blue light promotes plant growth and red light promotes plant budding. LED grow lights may look strange, but they contain both types.

  • Setting Up an Indoor Plant Growing Area

    How can you get enough light for houseplants and indoor garden areas? Here are three tips on how to best set up your space.

    Consider your indoor garden plot. Whether it is a single shelf, a basement area, or an entire room, look at how much space you have. Pot plants and wedding accordingly.

    Based on the type of plant, set the baskets or trays 4 to 8 inches apart to allow for growth and effortless accessibility for pruning and care.

    You will also want to ensure that you purchase lights that will illuminate your whole plantings area. You will need more than 1 bulb or light source to completely cover your growing region. Based upon the size, you might just have to use just 1 light for houseplants, or perhaps you need more.

    Sprouts flourish under a nurturing lighted environment.

    Few Benefits Of Growing With LED Light

    Plants That Grow Better:

    Alternative light sources emit more UV rays, IR beams and much more heat that are cause plants to dry and burn up. With LED grow lights, these elements which are counteractive to plant growth are significantly reduced. Therefore, plants grown will flourish instead of just survive.

    Moreover, some LED grow lamps make it possible for individuals to adjust the wavelength of light emitted to make sure plants get more of the needed spectrum of light. This will raise the all-around health of the crops.

    Faster Growth Cycles:

    Plants that are grown inside without the vulnerability to environmental cues don't follow routine planting seasons. With LED lights, an individual can provide unique wavelengths of light to facilitate different plant procedures for 24 hours every day.

    This permits the farmer to influence the behaviour and season of the plants. When using an LED light on auto-flowering plants, growers can affect flowering times in plants to increase production. This creates the possibility of having multiple harvests in 1 season.


    Traditional lighting techniques burn filaments, gas or other components to make light. The quantity of heat they create greatly reduces their durability.

    The low heat output of LED lamps significantly increases their lifespan. In actuality, they could last up to 50,000 hours. they're more convenient for growers since it will take years before an LED lamp will have to be replaced.


    LED's can be a excellent addition to hydroponics grow chambers. However, to get a one-stop solution that takes all the plus points of the lights, they're let down from the downsides. While this does not make them a poor light compared to traditional bulbs, they are simply not prepared to be overall replacements.

    This is truer in gardens where anglers want a fantastic spread of light. LED's can decrease energy bills for the period HID lamps aren't required, after which plants can find the boost in growth these HID bulbs still can deliver.

    A double setup for lights might be win-win situation for a grower. But generally, the reply about LED lights working for hydroponics is yes, as longs as growers do not expect miracles that are frequently used as part of their advertising for these new lighting fixtures.
