Ceramic Metal Halides: Benefits and Utility.
Ceramic discharge metal halides are the latest invention in the grow lights industry. Among the buyers and sellers, it is usually known as Ceramic discharge metal halide (CDM) or ceramic metal halide (CMH). These lights are 20%-30% more effective that usual metal halides. These lights also generate better colour spectrum as compared to other lights. This technology is not only used in indoor cultivation as grow lights, but these lights and technology is also used in television and films production, advanced digital photography, architectural lighting and street lighting. Ceramic metal halides are made of a ceramic arc tube, horticulture experts find this as a major reason for its higher efficiency. The major brand that is commonly known as LEC (light emitting ceramic) is a popular choice among the buyers of ceramic metal halides. The major upgradation that has been done in these lights is, that high intensity discharge lights like metal halide or high-pressure sodium lights emitted only specific spectrum of lights. That was the biggest drawback of these lights. Ceramic metal halides have full spectrum of lights and they emit light and radiations that are quite similar to sun rays.

While using ceramic metal halides, the biggest advantage is that it does not involve a lengthy installation procedure as compared to other high discharge lights. There are various types of lights which needs an external device to ignite the machine which is known as a blaster. The grow lights are started with the help of a blaster and lights take few minutes to ignite and warm up. Any such this thing is not required for ceramic metal halides. It does not require a blaster to ignite, on the contrary it starts with a very easy step of plugging on and plugging off.
Wide spectrum lights:
For cannabis growth or any other plant growth, the most important factor is the supply of lights to the plants. Every plant type has its own light requirement. Majorly plants require blue to violet light spectrum during seedling or vegetative phase. Some plants have other radiation and light requirement. Red to orange spectrum lights are required by many plants during flowering stage, fruiting stage or budding stage. Hence a grow light that is used for indoor cultivation should have full spectrum lights so as to fulfil all plants requirements and help them grow into a healthy stronger plant. Ceramic metal halides have the widest spectrum of lights which makes it the best option for large scale indoor cultivators.
Better development of plants:
Ceramic metal halides are among the latest inventions in indoor grow lights technology. It falls under the High intensity discharge lights. As other HID lights or metal halide or high-pressure sodium lights, these lights do not emit large amount of heat. Hence the problems that were caused by HID lights like burns in leaves, dryness in soil, overheating to the seedlings, are all avoided by ceramic metal halides. Also, the lights emit full spectrum lights, and the arc shapes tubes helps in plants development and plants get their natural green colour. The different spectrums in different stages with proper supply of heat enables higher rate of development in plants as compared to other grow lights.
Low maintenance cost and long lasting:
Although the initial cost of ceramic metal halides is highest and is not suitable for one-time growers or hobbyists. But for large scale indoor cultivators, Ceramic metal halides are the best option as they have low maintenance cost post installation. These lights need less hardware change and lasts longer than any other grow lights. Also, since it requires no external blaster to ignite the machine, the additional expenses of blaster and igniters are omitted. These lights also consume less energy as compared to metal halides and high-pressure sodium lights. Since the market is growing day by day for indoor cultivation and also of CMH, the initial costs have also started to come down.
CMH facilitates the highest CRI:
CRI (colour rendering index) is a calculative tool that measures the colours coming out of a light source as compared to the natural light source. Hence the higher the CRI index is, Better the CRI index, the more efficient the lights would be. Ceramic metal halides have the highest colour rendering index as compared to any other grow lights.
Higher growth rate of yields:
Many cultivators have reported that 1 unit of CMH of 315W is as productive as 1000W HPS light source. This is calculated in terms of yields. CMH has much higher growth rates than other grow lights.
The light source equipment of CMH is much more efficient that any other bulbs. It has longer life that other LEDs or HID lights. It may last for at least three years.
Availability is various sizes and shapes:
Ceramic metal halides are available in various sizes and shapes. Hence, the cultivator may choose the size and shape as per his requirement and grow area.
Generation of critical lights and radiations:
Ceramic metal halides have the widest spectrum of lights which makes it the best option for plants as it is the artificial grow light that has closest light spectrum that matches the spectrum of sun lights. Not only this, these lights provide the highest amount of ultra violet rays that is used by plants during their photosynthesis and also used in different phases of growth.
Generates less heat:
As compared to other high-intensity discharge lights, these lights come up with an updated feature, these lights are very effective when it comes to lights spectrum or generate lights that looks like sun lights, but these lights do not emit large amount of heat. These lights are helpful in keeping the plants and seeds warm, but it does not burn them or let the soil dry up fast. Extreme heat generation was the biggest problem with HID, metal halides or HPS lights. But ceramic metal halides are good for seed germination and flowering and fruiting stages and keeps maintains the temperature of the grow area as required by the plants.
