Basic Things you should know about High Pressure Sodium Grow Lights

What is a HPS grow lights?

Before we look at some of the best HPS grow lights in the market, it is good to understand what they are first. HPS stands for high-pressure sodium. HPS light comes in the form of a narrow arc tube held by a wire frame. HPS light contains xenon gas, high-pressure solid sodium and mercury.

How HPS light works

HPS light works by using ballast, which creates a pulse that stirs the gas in the bulbs or lamps. The ballast first ignites the xenon gas, which in turn generates a flow of electrons. The electrons heat up the arc producing a pale blue light. After this, the arc vapors mercury into gas generating a deeper blue color. Finally, the sodium gas vapors turn the arc into a yellow color spectrum.

These are all the colours that provide lighting effects that influence the growth of the crops. All the colours have different wavelengths depending on the gases inside them. Majority of the HPS bulbs are ideal for the FLOWERING phases of the crops because of their orange and red lights.

Though you can use the lights for other stages, it is better to supplement HPS grow lights with other lights during the other growing stages for even better yields. Before we look at the advantages and disadvantages of HPS grow light, we did a roundup of the best HPS grow lights in the market and came up with the following six products that you cannot afford not to try if you want the best out of your cannabis.

Less cost per wattage

Compared to LED lights, HPS bulbs have less cost per output wattage, which makes them very cost effective.

Cons

No blue colour spectrum

HPS lamps do not have the blue colour spectrum, which is crucial during the vegetative stages of growth.

Too much heat

Some of the HPS lamps produce too much heat, which may be damaging to the crops. To avoid this, you should always make sure there is a safe distance between the grow lights and the crops.

Mercury

Mercury is a dangerous chemical and you should therefore be very careful when disposing the bulbs. You should avoid throwing the in the trash as the substance could harm both animals and humans especially if there are pets and kids around the trash area.

Things you should know after deciding to get one HPS grow light

Before you go to the market to buy HPS grow lights, you should know about some things. The following guideline will help you in choosing the right lights for your crops.

Ballast

In the above products, you may have seen ballasts being mentioned severally. A HPS grow light is powered by ballast for it to work. The most common ballast is the digital because it is compatible with majority of the HPS bulbs.

It is also cooler and uses very little electricity to produce high light intensity. Digital ballast comes with dimming abilities, radio frequency shielding and bulb protection. It is also flexible which allows you to run varying wattages.

Reflector

Another common thing that HPS lights have is reflectors. Reflectors help to improve the light focus, which saves the life of the bulbs. The reflectors either come as open or air-cooled reflectors. Open reflectors ensure that your cannabis plants get as much light as they require. They also come with features that allow you to adjust the light.

This way you can place either place your crops nearer or further away from the light depending on the feature you choose. Air-cooled reflectors on the other hand captures the hot air in the grow tent and keeps it away from your crops. You can also connect the air-cooled reflectors to an air duct exhaust for better flow of air.

Coverage

HPS lights come in different sizes and wattages. Before you choose the size you want, you should first be sure of the size of your grow room. The most notable wattages of HPS bulbs are 150W, 250W, 400W, 600W and 1000W. The lower the wattage, the less distance the plants should be from the lamps. This is because the more wattage the lamps have the greater the heat and this could burn the crops.

Wattage	Plant’s distance from canopy/roof	Recommended Area
150W	6’’ or 15cm	1.5’ x 1.5’
250W	10’’ or 24cm	2.5’ x 2.5’
4000W	14’’ or 30cm	3.5’ x 3.5’
600W	18’’ or 45cm	4.5’ x 4.5’
1000W	24’’ or 60cm	6’ x 6’

Single End HPS Grow light

HPS grow lights come as either single ended bulbs or double-ended bulbs. Single ended bulbs look like the ordinary incandescent bulbs. The difference between them and the usual incandescent bulbs is that they use larger sockets known as mogul base.

They use an arc tube whose work is to manufacture light. The tube gets its energy from the bottom of the bulb, which is connected by a frame wire at the base.

DE HPS Grow Light

Double-ended HPS bulbs are some of the best in the market. They look just like the ordinary fluorescent tubes and they are easy to fix. They come with two wires at each end that you fix to a socket. Double-ended bulbs are popular with both professional, hobbyists weed growers, and there are several reasons why they prefer them to single ended HPS bulbs. Some of the reasons are;

Compared to single ended bulbs, they are much thinner, they have a more even light emission, they do not have a vacuum but instead have nitrogen gas, which helps the bulbs to generate more light, they are more durable and their degradation is much slower. The only reason why they do not go in larger quantities than the single ended HPS bulbs is that they are more expensive.

Cost

Price is another important factor to consider when buying your HPS grow lights. The good thing is that the light comes with different affordable prices, which gives you a wide choice to consider. The only other important thing to take into account is that you should always buy your grow lights from reputable vendors to avoid buying fake bulbs and lamps.

Conclusion

The grow light sector is one of the most competitive especially for indoor growers. The confusion comes in when selecting the best lighting systems for your crops during their growing phases. You can trust the above HPS grow lights to provide excellent results especially during the flowering phase of your cannabis.

They also give you superior and larger amounts of yields, which is what you are aiming for. To compare HPS grow lights with LED grow lights, you can read our earlier articles on the latter.
