What Exactly is an HPS Bulb?
An HPS bulb is a type of artificial light that’s commonly used for indoor gardening. The High Pressure Sodium Bulb, or HPS Bulb for short was developed during the 1950s due to the fact that outdoor low pressure sodium lamps didn’t provide enough visibility. Further technological experiments over the years gave us the bulbs that we know and use right now.
The HPS glass bulb contains a long rod called an arc tube and is made of ceramic. Inside this rod is the sodium and mercury that is needed to create the "arc," or light as we know it. And to hold it in place, it’s housed in a metal structure.
In order for these lights to work, a gadget called ballast is needed to power them up. With this contraption, you can do many things with your bulbs like adjust the intensity of the lights, depending on your plants’ needs.
Why Choose an HPS Bulb
They are Efficient
Gardeners still prefer the HPS bulbs as grow lights because they are effective at producing results. These kinds of lights radiate red and yellow light, and they encourage seedlings to grow and bloom flowers. They’re also perfect if you are eager to see your plants bear fruit. I tried them on my tomato plants and I did not have to wait long to see the results!
They are Long-lasting
The HPS light can last for a really long time so you can use it for as many times as you need it on different plant species without compromising efficacy, even at half its shelf life. In fact, some can even last for 24,000 hours!
They are Cost-Effective
Since they have lasting power, you won’t have to replace them for a long while. You can just focus on waiting for your next harvest. Who knows? You might even sell the extra produce and make a bit of money!
Choosing the Right HPS Bulb
Different factors can be considered when buying the right light source for your green project. Below are some of the basic things to remember before you make that purchase:
If you just need to nudge those seeds to full growth, then by all means choose a bulb that gives off blue or violet light. However, if your plants have fully grown and are ready to produce fruit, you can decide on a bulb in the yellow, red or orange range.
Take note that whatever color a bulb emits, it will still provide a general improvement to plant health.
Simply put, this is the brightness given off by a light source. Did you know that for each watt, HPS bulbs emit 60-140 lumens? A general rule of thumb is the higher the value, the better it is at helping plants manufacture food, also known as photosynthesis.
Of course, we need an HPS bulb with wattage that’s high enough to produce the heat our plants need. Among the units available for this kind of lighting, the 600 watt light is the most preferred. But if you just need supplemental heating, you could choose the lowest which is at 150 watts.
Limitations of Using HPS Lights
They Need a Ballast to Work
A ballast is an accessory to the HPS bulb that charges it with the right amount of power to make it work.
A word of advice: do your own research when choosing the right ballast for your bulbs. If you already bought one, make sure you carefully check the information on the package to get a ballast that’s compatible to use. This saves you time and money.
I happened to make the mistake of buying an electric ballast that didn’t work for the bulbs I had and I ended up paying for unnecessary fees. Try browsing online to get the best deals for your buck. Most items carry a warranty and offer replacements for defective units so you need not worry.
They Might Pose a Hazard to Health and the Environment
HPS lights give off harmful vapors if they become damaged. Prolonged exposure to these harmful substances like mercury can make you really sick.
From time to time, take stock of your bulbs. Change them after their expiration date. Get in touch with your local recycling center and learn how to properly dispose of these bulbs. This way, it’s safer for the environment as well as for you.
Our list includes some of the best HPS bulbs that you could buy for your starter garden. However, the true winner is the Ushio HPS light bulb as it is proven to be a technical masterpiece.
With its lightweight design, you can mount and change it easily. You can depend on it to wake those little seeds into sprouts. And if you have fully grown plants, the Ushio light can certainly nudge them into bearing, literally the fruits of your labor.
Gardening is a skill to master, and with the right HPS lighting, you’ll be an expert in no time.
