The only disadvantage indoor WEED growers have over outdoor growers is the lack of natural light from the sun. However, this disadvantage does not deter indoor growers from getting the best out of their cannabis. Indoor weed looks healthier and it grows faster than that grown outdoors.
What you may consider a disadvantage is therefore an advantage. Indoor growers can control the growth of the crops by using nutrients, water and an effective lighting system. Grow lights are therefore a necessity for every indoor weed grower. There are different types of indoor grow lights that weed growers use for the different cycles of crop growth.
The most popular are LED grow lights, MH, COB and HPS grow lights that we have reviewed in some of our earlier articles. There is another kind of grow light, which is also as popular as LED, and HPS grow lights. These are CMH or Ceramic Metal Halide Grow Light.

Things you should know CMH grow light
Basic Things you should know about a CMH grow light
What is the CMH (Ceramic Metal Halide) grow lights?
Also known as, LEC or Light Emitting Ceramic, the popularity of CMH is catching up with any weed growers because of the efficiency of the light, which is especially good for crop photosynthesis. CMH grow lights also go by the name Ceramic Discharge Metal Halide (CDM), the lights use ceramic technology and they have the qualities of metal halide and HPS grow lights.
The lights use ceramic arc tubes very similar to the tubes in HPS grow lights. They also operate at much higher pressures than the quartz tubes glass tubes of metal halide grow lights. CMH grow lights, just like all other grow lights, come with their own advantages and disadvantages. Before we review some of the best CMH grow lights in the market and below are detailed buying guidelines for ten of them but before that, below are the reasons why you should switch to chm grow lights.
(Advantages/Pros?) Why should you start using/switch to CMH grow lights?
The grow lights competition is one of the stiffest for indoor weed growers. For you to get the best results out of your crops, you need to keep up with the latest technology and do away with the old. CMH is one of the latest grow light technologies taking the weed growing market by storm.
Before you decide on whether you want to change to this new technology and give your crops better service, it is good to understand what makes hem a popular choice for many growers and what the downsides are.
- Better PAR efficiency
- Wide and finest Spectrum
- Better CRI
- Long- Lasting
- Heat Consumption
- Better Color Stability
- More Efficient
- Provide UV lights
Another good reason for the popularity of the CMH grow lights is their full spectrum coverage, which is the finest in the market. This the light accomplishes due to the highly effective ceramic arc tube. The ceramic arc tube unlike other types of tubes can resist high temperatures. The lights also come with a well-balanced plectrum that spreads evenly across all the crops, touching every one of their spots.
Better PAR Efficiency
One of the reasons many growers are switching to CMH grow lights is due their excellent PAR efficiency, which is much better than that of many other types of grow lights. Other grow light models such as MH and HPS waste too much energy, which does not help with crop growth.
Natural color rendering index
If we compare with other kind of grow lights then the CMH lights can provide us the highest measurement of natural Color Rendering Index (CRI). It shows us, how an object can be seen through human eyes and how well and elusively it can reveal the color shades. The higher number of CRI gives you a realistic view. If we rate sun light 100 CRI then a CHM grow light can produce 80-96 CRI. That’s why; it can show you the real view where the other lights will show you different type of colors like purple, blue or yellow.
Ceramic arc tubes have an advantage over other tubes and bulbs because they are resistant to heat and other problems. This makes the grow lights last longer than others without breaking down. The grow lights run for 24,000 hours, which is equal to running for a period of three years. For 20,000 hours, the grow light keeps a constant lighting and heat strength of 80%.
Despite running at high temperatures, CMH grow lights produce less heat compared to many other grow light models in the market. The bulbs of the grow lights do not burn the leaves of the crops and it is one of the best options to use in a grow room or a GROW TENT for a good yield from efficient growth.
Better Color Stability
CMH grow lights are consistent in their light and color dispensation. They do not lose their effectiveness or quality at any time throughout the growing cycles. Other lights lose their effectiveness after some time.
CMH lights are very efficient and the yield per watt from CMH grown crops is higher than that of many other grow lights. If you follow all the growing guidelines, you can have a yield of 20% more than, if you grew your crops under MH lights
Provides UV light
Besides offering full spectrum light, CMH grow lights also offer more UV lights than many other grow light models. Plants need UV lights for protection and proper growth. The light also helps during the vegetative stage and ensures that the crops grow with strong branches.
Downsides of Ceramic Metal Halide (CMH) grow lights (Cons/Disadvantages)
- Not best choice for flowering
- Provides UV lights
- Little Bit Expensive
- Quite high Heat Output
- It isn’t for all kind of ballast.
HPS grow lights are the best options to use for the flowering stage of your weed crop. This is because they provide more red spectrum than all other grow lights. CMH grow lights have a better-balanced light spectrum but they are not the best options for the flowering stage.
The grow lights provide UV A, UV B and UV C lights. Though the UV brightness of the grow lights provides the crops with enough protection and all they light they need for proper growth, they come with one disadvantage. UV C brightness may cause harm to the human’s naked eyes and it therefore important to wear protective eyeglasses and full-sleeved clothing while handling the lights.
Little Bit Expensive
Another disadvantage of the chm grow lights is that they are more expensive than many HPS grow lights in the market. Their processes are actually double that of HPS grow lights. They however save more energy and are more effective in light coverage. They also last longer, which makes them worth their high costs.
Quite High Heat Output
With over 700 nm lights, a chm is one of the highest heat-emitting bulbs.
Does not support all ballasts
The only ballast you can use with a CMH bulb is the magnetic ballast. You also can not place the bulbs in any other angle besides horizontally or straight up.
Things you should know before and after getting a CMH grow light
However, its much better to purchase a new one because CHM doesn’t work on so many type of electronic ballast for high frequency issue. The CHM bulb only supports on some good quality high end ballast with microprocessor. That’s why if you’re new with CHM technology then you should buy a full kit which is available with a fixture, bulb, reflector and everything in a package. It’s very easy to install and use.
An ideal CHM kit has square-wave technology ballast which will save you from EMI (ELECTROMAGNETIC INTERFERENCE) issues.

Comparison of CMH and Other Grow Lights
CMH vs. MH
Some people assume that ceramic metal halide and metal halide are the same but they are completely different. They however share the same technology but their constructions are different. You cannot use a CMH bulb in MH ballast and vice versa, CMH has a better light spectrum and it runs cooler than a MH light. Lifespans for the MH bulb are also shorter than those of a CMH bulb. MH is also more affordable than CMH.
|Efficient||Cheap in Price|
|Better Spectrum||Not better spectrum than CMH|
|Lifetime of 24,000 hours||Lifetime of 10,000 hours|
CMH vs. HPS
CMH and HPS feature the same bulb technology but with very slight differences. When it comes to effectiveness, HPS are a notch higher than CMH. Most of the PAR light from HPS lights is provided by the red lights whereas CMH lights provide a more balanced PAR for the flowering and vegetative phases of growth.
When it comes to efficiency, CMH are better than HPS lights and they have longer lifespans. Cost wise, HPS lights are more affordable than chm lights and they are better for the flowering phase.
|More efficient||Best for flowering stages |
|Balanced and better spectrum|| Quiet Cheap in price |
|More than 2x lifespan of HPS ||9000 hours of lifespan |
CMH vs. LED
LED lights have more advantages over CMH lights in that they are more energy efficient and they produce very low heat. You can place LED lights near the crops without the fear of them overheating while you have to be more careful about the distance between CMH lights and the crops. LEDs also have longer operating times as compared to CMH lights but they are more expensive.
CMH lights on the other hand are more affordable and have lower usable life times as compared to LED lights. LED lights come in different categories and there are more products in the market with factual descriptions from their manufacturers than there are with CMH lights. LEDs also have a better light coverage and you can use them for all growing phases of the crop.
|Affordable||Very simply target any PAR range|
|Quite low useable lifespan than LED|| Lower heat consumption |
|Longer Running Time|
