Which is better HPS or MH

In addition, HPS lights provide higher light intensity (lumens) than MH. This can be around 25-40% more lumens/watt than MH lights of the same wattage, and when it comes to flowering; the more light – the better the results.

Which is better led or HPS?

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).

How can you tell the difference between an HPS and an MH bulb?

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 bad for veg?

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 much area does 600W HPS cover?

600-Watt HPS grow lights are the most efficient HPS grow lamp. 600W HPS grow lights produce more light output per Watt used than other wattages and cover around 36 square feet. 1000-Watt HPS grow lights are the most powerful and cover a wider area of around 49 square feet.

Can I switching from HPS to LED during flowering?

LEDs Provide a Higher Quality Light Spectrum There was a time when switching from MH to HPS bulbs between veg and flower counted as tailoring your light spectrum to your plants’ needs. … When you switch from HPS to LED, your plants receive the blue hues they need for sturdy growth and root development.

What is HPS light?

High pressure sodium vapor (HPS) lights, similar to LPS lights, are a specific type of gas- discharge light (also known as a high intensity discharge, HID or arc light). The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp.

Can I use HPS and LED together?

The way HPS lighting should be installed is so that the light overlaps so shadows are reduced, and light penetrates in a horizontal direction. Having a mix of both HPS and LED lighting provides an ideal distribution of both diffuse and directional light.

What is the advantage of HPS?

Advantages. Most efficient member of the HID light family, 7 times as efficient as incandescent and over 2 times as efficient as mercury vapor. Warm-up period is 3-4 minutes, which is somewhat less than that of a mercury vapor or metal halide lamp. Long lamp life — 24,000 hours.

How many watts veg stage?

Veg Room Set Up A good rule of thumb is that between 10-20% of your total light wattage in the Flower Room will be used in vegetative growth. This means that if there are 50,000 watts in the Flower Room, there should be between 5,000 and 10,000 watts in the Veg Room.

Do HPS lights get hot?

HPS/MH operate at extremely high temperatures – 30000C/54000F. Much of that heat gets turned into infrared radiation. Infrared is a type of radiation that causes molecules to vibrate and heat up when it hits them. This infrared gets directed down on your plants just like the visible light radiation does.

How many T5 lights do I need for veg?

Figuring out the number of T5 grow lights you need for your plants all comes down to the lumens they’ll need. This is pretty easy, especially if you keep in mind that plants need 2,000 to 5,000 lumens per square foot. Smaller veggies, clones, and seedlings need around 2,000 lumens/sqft.

What is MH and HPS?

MH, or Metal Halide, and HPS, or High Pressure Sodium, are two types of High Intensity Discharge lights that give a brighter effect, and also help to save energy. Both the MH and the HPS are widely used for outdoor lighting. Well, both these lights have specific characteristics that differentiate one from the other.

Can I use a MH bulb in a HPS ballast?

Yes, you’re allowed to change your mind—at least when it comes to MH and HPS lighting. Although the two fixtures use what are normally incompatible ballasts, conversion bulbs will let you switch lighting types. Some conversion bulbs allow MH light to work with HPS ballasts, and others let HPS work with MH ballasts.

Can you flower under 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.

How high should my 600W light be?

The optimum hanging height for a 600W HPS system is only 40cm or 16″. Even at this low height a lot of light will shine on the side walls and have to be reflected down onto the grow. The reflective materials will not reflect all of the light and there will be some light lost (heating the walls).

What wattage HPS for a 4x4 tent?

600w HPS Grow Lights — Great for 4×4 Areas 600w grow lights are the perfect option for 4x4ft grow tents and grow rooms.

What is HPS quality?

Lighting quality of high pressure sodium (HPS) and light emitting diode (LED) luminaires are compared, based on roadway with a traffic island. Results indicate that the HPS luminaire can provide better average illuminance and average luminance values than the LED luminaire, resulting in positive visual performance.

Are HPS lights safe?

High-pressure sodium lights often are used for street and highway lighting. When these lights are turned on, they can produce potentially harmful levels of ultraviolet radiation. … However, cracked bulbs or covers can expose workers to harmful UV radiation, often without an individual even being aware.

Is HPS light bad for your eyes?

Are HPS Lights Bad For our Eyes? High pressure sodium lights contain a lot of red light, a small amount of blue light and very little UV light. For that reason, they are safer for our eyes. HPS bulbs are very powerful and can cause damage merely through their intensity.

When should I turn on my grow lights?

To play it safe, you could turn on the light a few days after you plant seeds, even if they haven’t popped up yet. Once sprouted, most vegetable seedlings and other garden plants require at least 12 hours of good light per day, along with 8 hours of darkness.

When did LED grow lights come out?

The first patent for the next evolution of grow lights would be for the Metal Halide bulb, patented all the way back in 1912! But it wouldn’t be until the 1960s that this invention saw more practical, widespread use for cultivation. At this same time in 1962, LED lights would be invented.

Why do HPS lights need a ballast?

HPS lamps require ballasts to regulate the arc current flow and deliver the proper voltage to the arc. HPS lamps do not contain starting electrodes. Instead, an electronic starting circuit within the ballast generates a high-voltage pulse to the operating electrodes.

What is the average life of sodium Vapour lamp?

The efficiency of a sodium vapour lamp under practical conditions is about 40-50 lumens/watt. Such lamps are manufactured in 45, 60, 85 and 140 W ratings. The average life is about 3000 hours and is not affected by voltage variations.

Are all HPS bulbs the same?

HPS bulbs also come in many different sizes, making them a flexible pick for your indoor garden. … As a general rule, 400w HPS bulbs are the most common, 600w HPS bulbs are the most efficient, and 1000w HPS bulbs are the most powerful (but also the hottest).

Why is HPS better for flowering?

The higher lumen or light intensity is also gotten from high-pressure sodium lights. The intensity is usually 25 to 40 percent greater than metal halide bulbs or even the same wattage. This is why HPS is better for flowering because the more light the better for the flowering plant results.

How do you space a grow light?

When it comes to HID grow lights, it’s best to keep them at least 12″ (30cm) away from your plants at all times. The stronger the light, the further you’ll need to hang it, so if you have a 1000w you may want to hang it at least 15″ (38cm) away.
