One 315W CMH is equivalent to one 1,000W HPS lamp in terms of yield, according to some suppliers. The same yields can be achieved with two 315W CMH lamps.

How much does a 315W CMH cover?
How much heat do CMH lights produce?
Four British Thermal Units are created by a watt from a grow light. One 600w HPS grow light puts off 2,400 BTU’s, whereas one 315 W CMH grow light puts off only 1,260.
Are CMH lights bad for your eyes?
This type of lighting isn’t any better for your eyes. A large amount of UV light is emitted by CMH. The effects of UV exposure on humans include eye diseases, skin cancer, and pterygia.
Is CMH good for flowering?
HPS bulbs are better for flowering than the CMH bulbs. They’re the perfect full cycle bulbs because they’re better at vegging. CMH lamps are more expensive than HPS lamps, but they have double the usable lifespan.
Which is better CMH or LED?
HPS’s put off more heat than CMH’s, but they don’t have as much heat. The savings depends on other factors such as the grow space and how much power is used for cooling. Replacing bulbs is an additional cost that a CMH grower will be aware of.
Is CMH better than HPS?
Plants don’t use a lot of energy producing light at ranges that are not efficient. CMH are a better single light solution because of their PAR efficiency. The color rendering index they have is a more natural one.
What’s better CMH or HPS?
HPS bulbs have around 3% blue in the spectrum, which is less than the other bulbs. Ceramic Metal Halide bulbs are new to the market. They are more expensive per watt, but they have a better spectrum and are more efficient.
What’s the difference between HPS and CMH?
You can get 130,000 lm in a single light with a 1000 watt HPS bulb. The highest amount of lm CMH lights can be found at 72,000 to 75,000. The HPS bulb is three times more powerful than the CMH bulb.
Are CMH hotter than HPS?
The grow room may need to be heated up in the winter due to the lower heat output of the LEDs. HPS’s put off more heat than CMH’s, but they don’t have the same effect.
What lights do professional growers use?
Most growers use HPS lights and T5 lights during at least one growth stage, and more than a quarter use LEDs.
How many amps does a 315W CMH use?
How many amps does a 630W CMH use?
A high output and energy efficient system is what the Hydro Crunch 630 Watt CMH Ceramic Metal Halide System is all about.
What is a CMH grow light?
Can you tell me about the CMH Grow Light? A ceramic metal halide grow light uses a ceramic tube as opposed to a standardMH grow light, which uses a standardQuartz tube. The CMH bulb is able to operate at a higher pressure because of the stronger tube material.
How far should CMH lights be from plants?
Two feet above the canopy is where the ceramic discharge lights will be hung. It is the standard hanging distance for most of the CMH lights. The 630 watt fixture can be started at the same distance.
How many watts per square foot is CMH?
30 to 70 watt per square foot is the ideal amount of light for a cannabis plant.
Is CMH full spectrum?
High quality light is produced by Ceramic Metal Halide grow lights. The light produced by them mimics the quality of sunlight. Some UltraViolet and InfraRed light will be produced by the grow lights.
Is CMH better for veg or flower?
Ceramic Metal Halide bulbs have recently been added to the market. They can be grown from seed to flower with one bulb. You will get more growth during the veg stage because of the higher efficiency and less stretching in the flower stage because of the high percentage of blue in the spectrum.
Why is HPS better than LED?
The heat per watt is more with an HPS fixture than it is with a LED one. This technology produces less heat and has a higher wattage equivalency than HPS, which is why it is more efficient in transferring energy to light.
What does CMH stand for in lighting?
We are often asked what the difference is between the two types of lighting. There are some differences between the two technologies. Both of them can be used for growing plants.
How far away should CMH lights be from plants?
If you want to find out how hot the light is, you should conduct a hand test. You should hang a CMH bulb two feet above the canopy of your plants if you want to estimate the distance between plant and light.
