While HID fixtures like HPS and metal halide have their place in the growing world, newer LED technology is superior in just about every way. Noble gas is present in this arc tube and often encompasses appropriate metal or metal salts. They produce bigger denser buds, and they offer a rich list of options. Grow lights have evolved from heavy magnetic, in-efficient ballasts and bulky reflectors to ultra-efficient dimmable and spectrum tunable Light Emitting Diodes (LED) and Ceramic Metal Halide (CMH) all-in-one fixtures. The metal halides present inside these bulbs help it produce the white-blue lights that the plants require during the vegetative stage. Finally, everyone’s favorite factor to consider, BUDGET! CBD Root Source All Rights Reserved. Metal Halide is the light of choice for indoor plant gardeners.

In conclusion, each technology, CMH and LED, are viable to successful grows however they speak to different methodologies and business initiatives. It has a high yield per watt of electricity, i.e., the amount of light it produces is worth the amount of power it consumes. LED’s offer the tunability to go from a vegetative blue spectrum to a flowering red spectrum with a turn of a knob. Also known as Light Emitting Ceramic (a trademarked term that only applies to a particular kind of CMH), or ceramic discharge metal halide (CDM), these types of lamps are a type of metal halide (MH) grow light.. No type of grow light is … The additional cost a CMH grower will realize is replacing bulbs.

An LED ran cooler than CMH's by at least 2°F, and overall 10°F lower temperature from a … Metal Halide is one of the most efficient grows lights in the growing industry. HPS lights are about twice as efficient in terms of power use as metal halide lights, so in other words, they run cooler and they cost you much less money to run as well. Studies have shown that the blue wavelength in light increases the overall growth of plants. The lights use ceramic arc tubes very similar to the tubes in HPS grow lights. The HPS spectrum mimics the outside autumn light increasing the plants demand for light. LEDs are the only lighting technology that can be designed to meet specific light spectrums for plants. HID light prices also vary by their wattage – 250watts has a price range of $150-$250, 400watts ranges from $200-$400, 600watts ranges from $300-$500 while 1000watts has a price range of $400-$600.

There are many short term and long term advantages of using LED fixtures to grow cannabis. The modern hobby and commercial cultivator now have the power to dial in spectrums specific to the plant strain they are growing. The quartz tube also contains halide salts, like silver chloride, that are used to fine-tune the color produced by the bulb. When you start a Metal Halide grow light, it will take a few minutes to reach its full potential because heating up the gas takes some time. Grow lights have evolved from heavy magnetic, in-efficient ballasts and bulky reflectors to ultra-efficient dimmable and spectrum tunable Light Emitting Diodes (LED) and Ceramic Metal Halide (CMH) all-in-one fixtures. In the picture to the left a 12 watt LED Grow Light similar to the Natural Daylight LED Aquarium Light showed superior growth to a 175 watt full spectrum Metal Halide. They run at cooler temperatures, get better yields than their counterparts, they are tremendously low on electricity and require little to no setup.
