Advanced Platinum Series P900 900w 12-band LED Grow Light


Growing cannabis indoors requires a lot of planning and preparation. You need the right equipment to provide the conditions your plants need to grow and develop well. One of these equipment is a grow light. As you may know, one of the most essential needed for plants to survive is sunlight. Plants utilize sunlight to produce their food through a process called photosynthesis. A grow light is an artificial type of light that substitutes for natural sunlight needed for your plants to grow. They provide a spectrum of light very similar to the sun so your plants can remain green and provide food for their growth. This artificial light mimics the sun by providing varying spectral output, temperature, and color.

There are different ranges and types of LED grow lights; the use of these lights depends on the strain being planted and what your plant needs. If you have decided to get a 900 watt LED light, you are in the right place. LED grow lights are known to produce even more yields, and the 900w light is nothing short of that. This because it produces exactly what your plants need to grow and thrive quickly, producing more yields than you anticipate, which is a good thing.

When dealing with LED grow lights, there’ a vast range of options to choose from; this makes it challenging to choose the best value for your money. Before going ahead to purchase an LED grow light, you need to research the different types and models available. This is why we have provided this detailed review to help you with this research. We will discuss some precautions and factors to put into consideration before choosing an LED light; particularly a 900w LED grow light.

What to Look for in a 900 Watt LED Grow Light

It is very important to get your money’s worth when shopping for an LED grow light. It’ll be quite disappointing to purchase one that doesn’t meet your needs. This is why there are certain factors to look out for when choosing a 900w LED grow light. When shopping for an LED grow light, you need to focus on the lifespan, how much energy it conserves, and the full spectrum it offers, not the unnecessary pictures that make it look attractive.

Full Light Spectrum:

This requires careful consideration. For your plants to thrive and grow well, you need a light wavelength that will stimulate photosynthesis so your plants can produce enough food for your plants. The light wavelength I usually in the blue and red spectrum because these provide a great amount of efficiency and helps to convert energy, light, and water into the materials needed for successful plant growth. These two light spectrum and wavelengths are of great benefit to your plants. Any LED grow light with a lot of white light is to be avoided because this spectrum is actually white light with a blend of yellow and green light, and these light spectra do not help with photosynthesis.

Energy Consumption:

This is another major factor to consider; this is not just about how much energy the light is consuming but how much your plants are getting. LED lights are known to operate without producing heat. Less efficient LED grow lights heat up quickly and mess with the humidity inside the grow tent, which can be bad for your plants. When looking to buy a grow light, choose those with the best efficiency, and invest in a cooling fan as well.

Heat Output:

LED lights don’t give off high amount of heat like fluorescent lights and halide lamps; for this reason, they are the most preferred option for growing cannabis. However, there are some low-quality lights that give off more heat than your plants can handle. Make sure to avoid these kinds of light; to do this, check for the heat emission capacity before purchasing an LED grow light.

Life Span:

The importance of this cannot be overemphasized. You don’t want to buy an LED light that dies out after a short time of using it. LED lights usually die out slowly, and with one as big and efficient as a 900w light, you probably won’t notice when it starts to die. A good LED light should last about 50,000 hours, which is about five years of daily use.

Shopping for a 900w requires a valuable amount of research because these lights are quite expensive. Getting a grow tent that is worth the price should be your top priority. To make your search much easier, we have done our research and put together some of the best 900 Watt LED light you can find.
