Is HPS or MH better for veg?

MH grow lights (metal halide) are suited best for vegetative growth and HPS grow lights are superior for flowering.

Is metal halide good for growing?

Metal Halide (MH) lamps typically emit a white colored light. Traditionally Metal Halide lamps have been used by indoor growers during the vegetative stage of plant growth. They are ideal for growing plants up to the flowering and fruit production stages because they mimic the spring/early summer seasonal sun.

Can you flower with metal halide?

The lack of red light does not fare well for cannabis plants long term, but does not cause a significant shade avoidance response light metal halide or tungsten lamps do, which emit high amounts of far-red, which causes plants to stretch.

Can you veg under a HPS?

In response to the general question, can you use an HPS bulb for veg, the answer is yes. Basically you can use just about any light out there for any stage of growth, the real question is how well do each bulb work for veg.

How can you tell the difference between MH and HPS?

Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange.

Is HPS good for veg?

What is the difference between HPS and MH lights?

Metal Halide (MH) lamps provide more of the blue spectrum, which is ideal for leafy crops, and/or plants that are in a vegetative stage. High Pressure Sodium (HPS) lamps provide more yellow/red spectrum, which is ideal for most plants that are actively fruiting and flowering.

Is metal halide better than LED?

LEDs tend to last much longer and are a more energy efficient and less maintenance intensive technology. Metal halides have long warm-up periods and a shorter lifespan but produce a very high quality light and are one of the most efficient lights when it comes to very cool color temperature outputs.

Can I veg with HPS?

Why is HPS better than LED?

The heat per watt is far greater with an HPS fixture compared to LED. This technology is far more efficient in transferring energy in to light, as it produces less heat and has a higher wattage equivalency to HPS (600w vs 1000w).

What is the difference between HPS and metal halide grow lights?

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. High pressure sodium grow lights produce up to 40% more lumens per watt than metal halide lights, and this then leads to much higher yields when marijuana is flowering.

Can you use metal halide lights for growing cannabis?

Yes, you can use metal halide lights if you want, but generally speaking, high pressure sodium grow lights are way better for the flowering stage and produce much bigger yields. Moreover, they are also much cheaper to run, and more versatile too. Most would agree that HPS grow lights are better than MH lights in more or less every way imaginable.

What is the difference between HPS and MHMH light bulbs?

MH stands for metal halide and just like HPS, it refers to the gas inside the bulb. Metal halide lamps give off a whiter/bluer light than HPS bulbs. This light looks more natural to our eyes (i.e. it is closer in spectrum to sunlight during the middle of the day).

How many lumens do you need for high quality HPS grow lights?

High quality HPS grow lights are specially engineered to produce a heck of a lot of lumens and a lot of red light, both of which are beneficial for marijuana flowering. On average, a 1,000 watt HPS grow light will put out between 130,000 and 155,000 lumens, which as you can tell, is a lot more than the metal halide counterpart.
