What Are CMH Grow Lights?
CMH, or ceramic metal halide technology is relatively new to the horticulture industry, but it’s made a big splash and quickly secured a role as on the must-try grow lighting styles there is. If you’re unfamiliar with these, they are essentially a modified MH (Metal Halide) grow light, but instead uses a ceramic arc tube. This results in a tube bulb that can withstand higher temperatures, and thus, creates the ideal formation of gasses in the arc tube. Because of this, CMH grow light creates a full spectrum of lighting for your plants. This means you can use them from seed to harvest.
Advantages Of CMH Light
- Spectrum
The CMH light spectrum combines the red-heavy HPS spectrum with the blue-heavy MH spectrum in one bulb, making it the perfect light for all stages of growth. With a high CRI, it is extremely close to natural sunlight, which is great for your plants and for your eyes (plants look more natural, making it easier to spot any discolorations or other issues).
- Efficiency
Ceramic metal halide gives you a much higher PAR (the amount of light that is usable by plants) per watt than any other type of lighting, apart from the most expensive LED grow light fixtures.
- UV Light
The CMH light spectrum also contains UV light of all type. Since UV-C light is harmful, the lamps use a glass filter to block that range. This leaves only UV-A and UV-B light, which many feel is beneficial to yield quality. There is no need for supplemental UV lights when using CMH grow lights for indoor growing.
- Lower Heat
CMH grow lights run much cooler than their MH and HPS counterparts. This reduces (or eliminates) the need for additional cooling equipment. They run hotter than light emitting diode lights, though.
- Long Lifespan
CMH bulbs last much longer than other HID or fluorescent lights. The standard rule of thumb for HPS or MH bulbs is to replace them after 10,000 hours of use. Good ceramic MH bulbs last over 20,000 hours. Moreover, they still retain 80% or more of their initial light output after 20,000 hours. HPS and MH lamps deteriorate much more quickly.
Here are three best CMH grow lights.
