Advantages of CMH grow lights over other lighting systems

Growers often struggle to differentiate between CMH grow lights from other grow lights. Probably, this happens due to the hype surrounding other grow lights. Nevertheless, choosing CMH to grow lights ensures that you get:

Better CRI

CRI (Color Rendering Index) refers to the ease in which the human eye sees an object. It also includes how easy it is to identify different shades of color. CMH grow lights give optimal CRI, compared to other grow lights. On a scale of 100, CMH gives between 80-96 of CRI, while the other grow lights give between 50-79 CRI.

UV light

Plants use UV light to produce better chlorophyll and grow quickly. Research shows that CMH grow lights that provide high-quality UV light, which is vital for the growth of cannabis plants. Besides, the grow lights also produce full-spectrum light better than their competitors in the market. 

Long-lasting service

Resistance to extreme heat and other natural causes make CMH grow light bulbs. A single CMH light can last up to 3 years (24,000 hours) with optimal light and heat capacities (about 80%). It is rare to find other grow lights with these properties.

Wide and fine spectrum

Another outstanding feature with CMH grow lights is their plectrum, which distributes light evenly across the plants. The CMH grow lights are arc-shaped, which makes them resistant to extremely high temperatures, and instead deflects the same to the plants. 

Effective heat consumption

The ability to run on high temperatures and still produce less heat than other grow lights make CMH grow lights extraordinary. The low heat protects the leaves from burning, making them the perfect solution for growing cannabis plants indoors. 

Better PAR efficiency

Getting an energy-saving, high-performance grow lights can be a big challenge. However, CMH grow lights boast of this combo, which makes them the best choice in the market

Wrap Up On The Best CMH Grow Lights

CMH grow lights are revered over other grow lights in the market due to their efficiency. The ability to regulate light, offer high-quality CRI and PAR, makes ceramic metal halides the best choice in the market. However, there are different CMH grow lights in the market, each offering unique qualities. Depending on your budget and the results you need when it comes to harvesting your yield, you should choose the one with optimal benefits.
