Best 300W LED Grow Lights in 2022 - Reviews

 Growing plants indoors has many benefits. First, plants generally grow best under very strict lighting schedules. Controlling your light sources basically lets you take whatever approach you want. You can also arrange plants to make light distribution more efficient. Plus, with indoor growing, you can control temperature and humidity; your plants are immune to outdoor risks like pests, rain, and theft; and you don’t have to worry about blocking your plants from neighbours or authorities. Growing plants indoors can give great results.

What lights do professional growers use?

The LED lights have finally attained equivalence with old-style HID lightings while proving more productive than all existing light systems that were used to grow indoor.

The best LED grow lights keep the grow environment cool whereas economically benefitting for running longer in the seen. Professional growers look for the lights with high PPFD ranges between 400–2000μmol/m²/s that provide consistent light through all growing stages of the plants, are more economical, don’t heat up and provides a full spectrum of light for the plants in their grow room.

They also look for the photonic pressure any light yields while in operation as excessive pressures can adverse the yield. Their demands for the full spectrum, high PAR, high PPFD, and low heat are only met through the use of the modern LEDs where they find satisfaction to grow in their grow room, confidently.

Best Grow Lights on the Market: Making the Right Choice

Thinking about what lights are best for growing plant in an indoor grow room? Chances are, you will be overwhelmed with the possibilities. Nonetheless, make sure to consider the factors that will be mentioned below to help you choose the best LED grow light on the market.

Spectrum
Lights come in different spectrums, which is why it is one of the most important considerations when narrowing down the possibilities. The best light spectrum for plants will depend on its growth. For the vegetative phase, the blue spectrum is recommended. On the other hand, to induce flowering, choose lights with red spectrum. Full-spectrum light, meanwhile, can be used at all stages of growth.

Wattage
This will be directly proportional to the power of the light. If you have a large grow room, you will need to invest in a more powerful light. On the other hand, if space is small and if the wattage is too much, you will most probably end up burning the plant.
Speaking of wattage, it will determine the right height between the plant and the lamp. If you are using an HID grow light, here is the suggested distance:

400-watt HID: 12 to 19 inches
600-watt HID: 14 to 25 inches
1,000-watt HID: 16 to 31 inches
On the other hand, if you are using LED lights, here is a quick guide for you to follow:

240 to 400-watt LED: 16 to 30 inches
450 to 550-watt LED: 20 to 30 inches
600 to 850-watt LED: 24 to 26 inches
900-watt and above LED: 26 to 42 inches
Lastly, if you are using CFLs and T5s, you can position them about five inches above the canopy of the plant. They do not produce intense heat, which is why there is a slim chance that it is going to burn the plant.

Lumen
Scientifically speaking, lumen refers to the amount of light that is emitted per second from a specific source. For the plants to be healthy, it needs to be exposed to a certain amount of lumens, which is why you need to choose a light that will be able to produce such. For each plant, the minimum requirement would be around 2,500 to 3,000 lumens per square foot. During the vegetative stage, the plant may need up to 5,000. Meanwhile, during the flowering phase, it might need as much as 10,000 lumens.

Kelvin
As you pick the best lights for indoor growing, another technical specification that would matter is the Kelvin. This also refers to the light color or light temperature. During the growing or vegetative phase, choose a light that has about 6400 kelvins, which has a daylight or cool color. It has a blue spectrum. This will replicate the color of the sun during summer or spring.
On the other hand, for the flowering stage, it should be about 2700 kelvins, which is warm and has a red spectrum. It has a color similar to that of the sun during fall or winter.

Conclusion

Getting a grow light is a good idea if your windows do not provide enough light, or you are simply trying to overwinter your succulents indoors. Whatever your reason, the grow lights increase your plants’ strength. We considered several factors when choosing them. These criteria are important because they help you make the right choice of your equipment.
