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 good for veg?
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 better than HPS?
Plants 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 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.
Can you veg under HPS?
The answer is yes, if you want to use an HPS bulb for vegetables. You can use any light you want for any stage of growth, but the real question is how well each bulb works for veg.
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.
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.
Is CMH or LED better?
The HPS’s put off more heat than the CMH’s do. The savings depends on other factors such as the grow space and the amount of power used. Replacing bulbs is an additional cost that a CMH grower will be aware of.
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. There are a number of effects of UV exposure on humans.
What does CMH stand for in lighting?
We often get asked what the differences are between metal halide and ceramic metal halide. There are some fundamental differences between the two technologies. High intensity discharge lamps can be used to grow plants.
How do I know if my CMH bulb is bad?
The lamp may be a different color, or it may be pink, if the Metal Halide light bulb needs to be replaced.
Whats better led or CMH?
50,000 hours is the time it takes for a light bulb to 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 past 5 years, CMH’s provide a greater gram per watt because of their higher PPF.
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.
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 good veg?
It is not strongly recommended to use three types of lights for a full growing phase. During the vegetative phase, it is normal to begin with CMH.
Do professional growers use LED lights?
Growers can use just one grow light system at every stage of growth because of the minimal maintenance requirements. This is due to the fact that most LEDs have spectrums that are designed for the whole growth cycle.
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. 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.
How far should CMH light be from plants?
Two feet above the canopy is where the ceramic discharge lights will be hung. That is the standard hanging distance for most of the CMH light models. 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 my HPS system? The ideal location for your HPS system is between 12 and 18 inches away from your plant.
How high should lights be above seedlings?
If you want to keep the lights above the plants, you should move the lamp upward.
How do you know if your plant is getting too much light?
The most common sign of a plant not getting enough light is a dull green color, as well as the dropping of leaves. If your plant gets too much light, it will lose leaves, singed tips, and burn patches.
