While those of HID grow lights are iPower, Apollo Horticulture, Sun system, Vivosun, Yield Lab, Eye Hortilux, Digilux, Ushio and many more. You need to maximize ROI in within 1-2 years, You need greater canopy penetration for the strains you are growing, Need the beneficial UV spectrum for maximum terpene resin production, Need to maximize your gram per watt and flower quality, Have a long-term plan with current LED technology, Need an exact spectrum wavelength to grow a specific strain, Yield quality and quantity are not paramount. Metal Halide is the light of choice for indoor plant gardeners. 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. Metal Halide (MH) Metal halide is a HID style grow light. These are approximate price averages for LED lights on the market.*. There is a growing (pun intended) number of indoor growers that are choosing ceramic metal halide (CMH) bulbs as their lighting of choice. LED bulbs last 50,000 hours compared to 20,000 for CMH. HID grow lights are significantly cheaper than LED grow lights, however, they may not perform as well. 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. Tried a 315 cmh for a few runs. Check it out on our website here! Like I wrote above, both LEDs and CMH grow lights are effective at growing plants. Increased ceiling height allows for better heat management, better air-flow capability and more even light coverage for fuller and taller flower strains. The initial cost of an LED is 2 to 4 times the cost of a comparable CMH fixture. The light … Similarly, metal halide lights have a far shorter lifespan than LED bulbs. There are many short term and long term advantages of using LED fixtures to grow cannabis. LED grow lights may be the best for growers who are looking to harvest half to one ounce of cannabis a month. HID grow lights fall under two category types: the Metal Halide (MH) and High-Pressure Sodium (HPS). This heat can be utilized to achieve the ideal temperature for your growing methodology, for example, if you are using CO2 injection. It’s an electrical lamp with high-intensity discharge (HID) gas. However, ceramic metal halide bulbs run a lot cooler than MH and HPS bulbs by about 8°F. Let’s talk about the size of your grow. CMH’s closely mimic the sun, provide the highest gram per watt, and even provide the coveted good UV wavelengths that fend off mold and mildew as well stimulate plant vigor and greater resin and terpene production.

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. The modern hobby and commercial cultivator now have the power to dial in spectrums specific to the plant strain they are growing. LED can convert 85 to 95% input energy into visible light, while metal halide lamp can only turn around 35 to 50% energy to lights – majority of energy is wasted as heat loss because of its unique working mechanism. LED halide lamps have a longer lifespan than metal halide lamps.Although the life expectancy ranges depending on various other factors including the size of the lamp and its quality.

A light emitting diode is an electrical light source that possesses the properties of a semiconductor which in turn emits visible light when a certain amount of electric current passes through it. HID and LED grow lights are leading the way in the grow light technology as users watchfully move away from halogen bulbs in the automotive market. So historically, Metal Halide lamps, even the new and highly touted Ceramic Metal Halide lamps have been used primarily for Vegetation phases of growth, where the red spectrum is less important, and possibly for the last 2 weeks of ripening. CMH fixtures put off more heat than LED’s, but less heat than their HPS counterparts. You will be buying replacement CMH bulbs after 12-18 months of use. Required fields are marked *. This could be a good thing if your ceiling height is less than 8ft and really need to factor in heat management. HPS grow lights emits light in orange to red spectrum, which makes them efficient and the best for use during the flowering stage of plants like marijuana, while their lack of emitting light in the blue spectrum makes them the best for the vegetative juncture of indoor plants where a natural source of light is unavailable. LED, HPS, CMH, CFL… all of these letter combos can start to get confusing fast. This means that many growers with HID light setups have separate veg and flowering lights or at least multiple bulbs, which … Therefore, you will incur the cost of more bulbs utilizing CMH technology, but you will optimize your light cycles and extend the timeframe to replace bulbs.
