HPS bulbs are better for flowering than CMH bulbs. They are the perfect full cycle bulbs because of their improved vegging. CMH lamps are more expensive than HPS lamps, but they have double the usable lifespan.

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 is more natural for them.
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 have recently been added to the market. They’re more expensive per watt but they have a better spectrum and are more efficient than HPS.
What’s the difference between HPS and CMH?
A 1000w HPS bulb can give you 130,000lm in a single light. 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 as much heat.
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.
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 time it takes for LEDs to work compared to 20,000 for CMH. 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 past 5 years, CMH’s provide a greater gram per watt because of their higher PPF.
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. It is possible to estimate the distance between plant and light, but you should hang a CMH bulb two feet above the canopy of your plants.
Can you flower under CMH?
There is no more complete PAR spectrum in a single grow light than there is in HPS lamps. CMH and HPS may be combined to give a boost to the red spectrum which benefits flowering crops.
Is CMH or LED better?
HPS’s put off more heat than CMH’s, but they don’t have the same effect. 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 better than HPS?
Ceramic Metal Halide bulbs have recently been added to the market. They’re more expensive per watt but they have a better spectrum and are more efficient than HPS. They can be grown from seed to flower with one bulb.
How long do CMH grow lights Last?
A CMH bulb can be used for up to 24,000 hours. While the lifespan of a grow light depends on the grower’s use, CMH bulbs or lamps are usually known to have long lifespans. You will be able to grow the same bulb for a long time with this.
Are LED grow lights as good as metal halide?
Compared to other technologies, LEDs are more energy efficient and less maintenance intensive. When it comes to cool color temperature outputs, metal halides are one of the most efficient lights because of their long warm up periods and shorter lifespans.
Can I mix LED lights with HPS lights?
The way HPS lighting should be installed is so that the light overlaps so shadows are minimized, and light penetrating in a horizontal direction. An ideal distribution of both diffuse and directional light can be achieved with a mix of both HPS and LEDs.
How far should CMH lights be from plants?
The first thing to do is hang the ceramic discharge lights above the canopy. It’s the standard hanging distance for most of the CMH lights. The 630 watt fixture can be started at the same distance.
How far should a 600 watt HPS light be from plants?
How close can I get to my plants with the HPS system? The ideal position for the HPS system is between 12 and 18 inches away from the plant.
Is grow light bad for eyes?
Plants can be harmed by grow light if it is used wrong. The lights can cause damage to your eyes. With today’s high power LEDs, this is truer than it has been before. Don’t wear sunglasses if you look directly into the LEDs.
Are plant lights safe for humans?
The majority of the wavelength is not harmful. The ultraviolet light from the grow lights can be harmful to your eyes. HPS grow lights and metal halide grow lights are included in this. You have to use the best led grow lights if you want to be safe.
How do you know if your plant is getting too much light?
If your plant isn’t getting enough light, there are a number of signs that it is not. If your plant is getting too much light, it will lose leaves, singed tips, and burn patches.
