One of the biggest disadvantages indoor Cannabis growers experience over outdoor enthusiasts is the absence of natural light from the sun. It’s a great thing that there are different types of grow lights available to fulfill this need. Now, indoor plants even look healthier and yield faster than those grown outdoors. Among these popular lights are LED grow lights, COB, CFL, and HPS. Yet, another type is starting to share the limelight -the CMH or the Ceramic Metal Halide grow light – a cutting edge grow light for better greens.

CMH lights are becoming a popular alternative to many Cannabis growers due to its efficiency, especially during the photosynthesis process.

Here are some of the advantages and disadvantages of CMH Lights:
