HPS’s put off more heat than CMH’s, but they don’t have as much heat. The savings depends on other factors in the grow space, such as power usage. Replacing bulbs is an additional cost that a CMH grower will be aware of.

Are CMH lights good for flowering?
HPS bulbs are better for flowering than the CMH bulbs. They are the perfect full cycle bulbs because of their improved vegging. CMH lamps make up for their higher cost with double the usable lifespan.
Is CMH better than HPS?
Plants use a lot of energy producing light at ranges that are not efficient. CMH are a better single light solution due to being more PAR efficient. The color rendering index is more natural for them.
How far should CMH lights be from plants?
The first thing to do is hang the ceramic discharge lights above the canopy. It is the standard hanging distance for most of the CMH lights. The 630 watt fixture can be started at the same distance.
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.
Are CMH lights good veg?
It is not strongly recommended to use three types of lights for a full growing phase. During the vegetative phase, it’s normal to begin with CMH.
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. The high percentage of blue in the spectrum will result in less stretching in the flower stage and more growth in the veg stage.
Is CMH full spectrum?
High quality grow lights are produced by Ceramic Metal Halide. The quality of sunlight is mimicked by the light they produce. Some UltraViolet and InfraRed light will be produced by the grow lights.
Whats better led or CMH?
50,000 hours is the amount of time that led bulbs last. CMH is the best choice if you want the greatest yield return within a period of 1 to 2 years. Even if you keep your grow space for more than 5 years, CMH’s provide a greater gram per watt due to their higher PPF and canopy penetration.
How far away should CMH lights be from plants?
If you want to find out how hot the light is, you should do 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.
Can you flower under CMH?
The only lamps that offer a more complete spectrum in a single grow light are the HPS lamps. CMH and HPS may be combined to give a boost to the red spectrum which benefits flowering crops.
Are CMH lights safe?
It’s always better to be safe than sorry, that’s why it’s important to note that the lamps are safe. If you want to keep up with your competitors, you should consider using ceramic metal halide grow lights. If you do, you’ll be happy when the harvest is over.
Are CMH bulbs dangerous?
Being outside of our range of vision is beneficial for plant growth and development because of the UV radiation provided by the CMH grow lights. UV A, UV B and UV C are harmful to the eyes.
Why do metal halide bulbs explode?
It’s possible that too much current could cause the active component of the MH to become overheated. You have to be aware of that as well. The lamp would be destroyed by the same heat surge as before.
Do high pressure sodium lamps explode?
The lamps are made with a highly volatile substance called sodium. There is a chance that the sodium may explode if it is exposed to air.
What are energy saving bulbs?
Energy saving lamps use advanced technology to reduce the amount of electricity used to generate light compared to traditional light bulbs. A light emitting diodes bulb is an example of an energy saving lamp.
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 1,260.
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 are less hot.
Are CMH lights bad for your eyes?
This type of lighting isn’t any better for your eyes. The UV light emitted by CMH is large. There are a number of effects of UV exposure on humans.
Do CMH lights run hot?
The CMH systems use ceramic, which allows the bulb to get hotter, giving you that perfect spectrum of light. That’s why it works at higher pressure.
Does more light equal more yield?
Light does equal yield, so growers can compare their current light levels to the 1,500PAR target. The yield increase is 33 percent if you move from 1,000 to 1,500 PAR.
