Factors to When Buying an HPS Grow Lights

When buying an HPS grow light, there are several factors to consider. The best way to know if an HPS grow light will work for you is by reading some reviews from other growers. The following are some general tips that can help you get started:

Size and Weight

The size and weight of your HPS lights will depend on how many watts they are rated for and their height, but generally speaking, 1 watt per square foot will cover a small garden about 2'x4'. Of course, you'll need more watts per square foot if you have a larger space.

For example, if you have 10 square feet of growing space with 2 watts per square foot, you'll need two 1-watt HPS bulbs (40 watts total), which would be fine for most growers since they don't need much light anyways!

Also, if you have limited space and need an efficient light source, it's important to find a light that is small in size and has a large reflector area. The more surface area that the light has, the more photons it can produce and the better chance you have of growing successful plants with it.

Light Spectrum

You want to ensure that your new HPS grow light gives off enough lumens for your specific needs. A higher light output means more intense light and more plant growth potential.

The light spectrum your plants need to grow differs from their food needs. Plants need light in the blue part of the spectrum, which includes red and orange colors. They also need to be exposed to enough red light for them to be able to absorb it and use it for photosynthesis. On the other hand, plants need less blue light than they do green or red.

Color Temperature

The color temperature of an HPS grows light is the color of the light produced by the bulb. It's measured in Kelvin. The higher the number, the warmer and more yellowish the light will be. For example, a blue-light bulb has a color temperature of around 2800K and can be used for plants that prefer warmer temperatures.

When looking at HPS lights, most people are interested in cool white or neutral white bulbs because these produce very little heat and have low blue spectrum UV rays compared to other colors on the spectrum, such as red or infrared (IR), which can cause problems with plant growth like sunburns or sick leaves).


How powerful does your grow light need to be? Is it just enough for one plant, or are you planning on growing more? It's important information because if you have an inadequate amount of power available, then your plants will suffer. It's not worth it when they can grow faster and healthier with a higher-quality light source.

The power rating of your HPS grows lights is how many watts they produce. So, the higher the wattage, the more powerful they are and will produce more light. So, you can grow more plants at once with less energy consumption.


HPS grow lights are more efficient than fluorescent bulbs because they do not require extra ballast or reflector to work properly. They also work better when combined with metal halide lamps because they can increase light output by up to 30%.

The efficiency rating on an HPS light is measured in lumens per watt (lm/w). The light is generally more energy-efficient and uses less electricity overall as the number increases.

Size of Your Garden

The size of your garden determines the type and number of HPS grow lights you need. The size of your garden will also determine how many watts are required for your garden. For instance, if you have a small garden with a small number of plants, you will only need two or three lights per square foot. On the other hand, if you have an extensive garden where you want to grow many different plants in a single space, you will need more than one light per square foot.


The cost of the lighting system will depend on what kind of lights you are looking for. The most expensive ones are metal halide lamps and high-pressure sodium bulbs. The average price of HPS grows around $400-$500, while T5 fluorescents cost under $100.

Generally, the cost of HPS lights varies depending on the size of the light bulb and its power consumption. The more powerful the bulb, the higher the cost of the light. The bigger it is, the more energy it needs to produce light. Also, you have to consider its warranty period and replacement costs.

What’s the Best HPS Grow Bulb?

The best high-pressure sodium lights are the one that works best for you and your setup. You can use a variety of bulbs, but the best HPS grow lights are those with a high PAR (active photosynthetic radiation) rating.

PAR is measured in lumens per square foot and is important because it helps to promote healthy growth by encouraging natural light to reach your plants. The higher the number, the lighter your plants get from each bulb.

If you're growing indoors, an HPS bulb will provide more than enough lighting for most setups. However, if you're outdoors or growing in greenhouses, you'll need to look at your setup's wattage and how much space you have available for it all to work optimally.

What Are the Benefits of Using an HPS Grow Light?

HPS grow lights have many benefits over other types of lighting:

  1. First, they are more efficient than other types of grow lights. They use less electricity so that you can save money on your electricity bill.

  2. They provide higher PAR levels than CFLs or LEDs, which means they will yield better results when growing cannabis.

  3. The more intense light output than CFLs and LEDs

  4. Higher efficiency than T5s

  5. No need for ballasts or dimmer switches

  6. Longer lifespan than CFLs and LEDs

  7. They can be used with any media such as soil, coco coir, hydroton, etc.

How Can You Optimize Your HPS Grow Light for Cannabis Growth?

To optimize your grow light for cannabis growth, you need to know how your lighting system works.

The most basic fact is that you need to match the spectrum of your grow light to that of the plants you're growing. So, for example, if you want to grow plants that are more suited to flowering (and thus produce higher yields), your grow light needs to be red or blue, with a temperature around 700 degrees Kelvin.

If your goal is to produce the most potent buds possible, then you need a red or blue spectrum with a temperature around 800 degrees Kelvin. Do this by using fluorescent lamps and reflectors with an adjustable angle.

These are known as HPS lamps or high-pressure sodium lamps. They work by putting a large amount of energy into the bulb so that it heats up very quickly and can produce intense heat; this results in higher yields and faster flowering times for many strains of cannabis plants.

Make the Right Decision!

The Best HPS Grow Lights are the ones that provide the most lumens per watt (lm/watt). It's important because it means that a grower can use less expensive light bulbs and get comparable results.

The Best HPS Grow Lights also have a long lifespan. Since these lights are designed to last for years, they need to be built to withstand wear and tear.

Finally, the Best HPS Grow Lights should be easy to set up and operate. If you can't compute how to use it on your first try, then maybe you shouldn't be growing indoors!
